    Abstract We studied nonsparsely diluted mean-field models that differ from sparsely diluted mean-field models, such as the Viana–Bray model. When the existence probability of each edge follows a Bernoulli distribution, we rigorously prove that the free energy of nonsparsely diluted mean-field models with appropriate parameterization coincides exactly with that of the corresponding mean-field models in ferromagnetic and spin-glass models composed of any discrete spin S in the thermodynamic limit. Our results is a broad generalization of the result of a previous study (Bovier and Gayrard 1993 J. Stat. Phys. 72 643), where the densely diluted mean-field ferromagnetic Ising model (diluted Curie–Weiss model) with appropriate parameterization was analyzed rigorously, and it was proven that its free energy was exactly equivalent to that of the corresponding mean-field model (Curie–Weiss model).

    Abstract We study the random-field Ising model on a Dyson hierarchical lattice, where the interactions decay in a power-law-like form, $$J(r)\sim r^{-\alpha }$$ , with respect to the distance. Without a random field, the Ising model on the Dyson hierarchical lattice has a long-range order at finite low temperatures when $$1<\alpha <2$$ . In this study, for $$1<\alpha <3/2$$ , we rigorously prove that there is a long-range order in the random-field Ising model on the Dyson hierarchical lattice at finite low temperatures, including zero temperature, when the strength of the random field is sufficiently small but nonzero. Our proof is based on Dyson’s method for the case without a random field, and the concentration inequalities in probability theory enable us to evaluate the effect of a random field.

    Abstract The interpolation method is a powerful tool for rigorous analysis of mean-field spin glass models, both with and without dilution. In this study, we show that the interpolation method can be applied to Ising spin glass models in one dimension, such as a one-dimensional chain and a two-leg ladder. In one dimension, the replica symmetric (RS) cavity method is naturally expected to be rigorous for Ising spin glass models. Using the interpolation method, we rigorously prove that the RS cavity method provides lower bounds on the quenched free energies of Ising spin glass models in one dimension at any finite temperature in the thermodynamic limit.

    Abstract Recently, Mori (2011 Phys. Rev. E 84 031128) has conjectured that the free energy of Ising spin glass models with the Kac potential in the non-additive limit, such as the power-law potential in the non-additive regime, is exactly equal to that of the Sherrington–Kirkpatrick model in the thermodynamic limit. In this study, we prove that his conjecture is true on the Nishimori line at any temperature in any dimension. One of the key ingredients of the proof is the use of the Gibbs–Bogoliubov inequality on the Nishimori line. We also consider the case in which the probability distribution of the interaction is symmetric, where his conjecture is true at any temperature in one dimension but is an open problem in the low-temperature regime in two or more dimensions.

    Recently, several powerful machines dedicated to solving combinatorial optimization problems through the Ising-model formulation have appeared. The trigger for the paradigm shift to a specialized machine for solving optimization problems was the D-Wave machine, which implements quantum annealing. Quantum annealing employs quantum fluctuations to find an optimal solution to an optimization problem with discrete variables. In particular, we input the optimization problem in the form of the Ising Hamiltonian, which is a specialized form of the quadratic unconstrained binary optimization problem. However, when we employ quantum annealing for a practical optimization problem, there are several issues. One typical issue is absence of the detailed form of the cost function, which characterizes the optimization problem. To input problems into specialized machines for solving an optimization problem, it is necessary to determine the unknown parameters within the Ising model. We propose a method to estimate the unknown parameters in the Ising Hamiltonian using compressed sensing. Furthermore, we analyze the theoretical limitations of our proposed method by employing the replica method, which is a sophisticated tool in statistical mechanics.

    We generalize a mathematical model in the item response theory into that in the Boltzmann machine learning to detect "cheating students". The cheating students are hopefully expected to be rare under normal condition holding tests. (We strongly hope!) In other words, the cheating students are expected to be sparse. In the present study, we employ a greedy algorithm, the decimation algorithm, which is free from the arbitrary coefficient. We confirmed that, when the sparseness is strong, the decimation algorithm outperforms the L1 regularization and establish a basic technique to detect the cheating students.

    More details Close

    We study synchronous phenomena of a coarse-grained power grid model, the<br /> swing equation, on small-world networks. We show that its steady state, which<br /> stands for the normal operation of the power systems, can be realized even if<br /> the phases are disordered. In addition, we prove the linear stability of steady<br /> state with small-different phases between the adjacent oscillators. On the<br /> other hand, a trigger of instantaneous power failure, which is described by the<br /> hysteretic transition, might disappear on an appropriate small-world network.<br /> This result suggests that the small-world connection would potentially prevent<br /> the massive blackouts.

    The recent work, Nemoto and Sasa [Phys. Rev. E, 83: 030105(R) (2011)], has<br /> shown that large deviations of the current characterizing a nonequilibrium<br /> system are obtained by observing the typical current for a modified system<br /> specified by a variational principle. In the present study, we will give a<br /> generalized version of the Nemoto-Sasa study by extracting a hidden<br /> mathematical structure from the fluctuation-response relation which is<br /> well-known in statistical mechanics. Here, the minimization of the<br /> Kullback-Leibler divergence plays an essential role.

    We show several calculations to identify the critical point in the ground<br /> state in random spin systems including spin glasses on the basis of the duality<br /> analysis. The duality analysis is a profound method to obtain the precise<br /> location of the critical point in finite temperature even for spin glasses. We<br /> propose a single equality for identifying the critical point in the ground<br /> state from several speculations. The equality can indeed give the exact<br /> location of the critical points for the bond-dilution Ising model on several<br /> lattices and provides insight on further analysis on the ground state in spin<br /> glasses.

    We show two fascinating topics lying between quantum information processing<br /> and statistical mechanics. First, we introduce an elaborated technique, the<br /> surface code, to prepare the particular quantum state with robustness against<br /> decoherence. Second, we show another interesting technique to employ quantum<br /> nature, quantum annealing. Through both of the topics, we would shed light on<br /> the birth of the interdisciplinary field between quantum mechanics and<br /> statistical mechanics.

    Quantum annealing is a generic algorithm intended for solving optimization problems by using quantum fluctuations. This algorithm can be regarded as a generic technique in quantum computation. Quantum annealing is very simple and yet applicable in principle to any optimization problems. It is also closely related to quantum adiabatic algorithm. In this article, we elucidate the current status and present a future outlook for quantum annealing.

    In this research, we aim to advance quantum error correction, which is a key technology for realizing quantum computers. We focus on the error correction process, which consists of “error detection” (observation of quantum state) and “error correction” (manipulation to quantum state) based on the detected signal, and obtain various results on the estimation of quantum state and design and generation methods of quantum error correction codes. Specifically, we have the following results; 1. physically realistic quantum coding and decoding methods and their robustness against thermal noise, 2. quantum adaptive control, 3. analysis of reasonable quantum information for quantum estimation, 4. quantum state smoothing, 5. quantum annealer performance analysis, 6. noise-driven quantum annealing, 7. analysis of quantum Ising model, and 8. estimation of quantum Ising model.

Furthermore, by utilizing this computational infrastructure, we realized a high-performance polymer material design and development platform by integrating computational science and data science. This high-performance polymer material design platform has made it possible to clarify the physical properties of polymer materials on a scale and with a precision that cannot be achieved with conventional computational techniques. Furthermore, the establishment of a high-performance, high-quality clustering technique using quantum annealing technology has demonstrated the possibility of developing new material candidates that cannot be found by conventional methods.

    The use of machine learning for the development of highly functional materials is the main focus of materials informatics. However, for the safety of the materials development, it is necessary to explain the predicted functions of materials in terms of what humans can understand. In this study, we have investigated the relationship between the structure and function of a material, which are two essential elements of human understanding in materials science, and have shown that the three-dimensional structure of a material and the structure of a material suggested by its molecular formula can indeed be used to predict the physical properties that the material will exhibit. We also clarified the trade-off relation between computation time and computation accuracy for a solver of an optimization problem, which typically appears in the learning phase of machine learning. This is expected to lead to the construction of more efficient machine learning algorithms.

    Some formulations of supervised learning of probabilistic graphical models by conventional belief propagation methods have extended to supervised learning by means of density matrices from the standpoint of quantum mechanical version of cluster variational method. The formulations for quantum statistical supervised learning was released as the book chapter of English book (https://doi.org/10.1007/978-981-16-4095-7_10). Furthermore, we have shown that good performance can be expected in the quantum statistical machine learning systems with low-dimensional state vectors for some application examples such as image generation.

    Strongly correlated electron compounds offers various practically useful functionalities such as magnetism and superconductivity. The susceptibility represents the response to an external field, and plays an important role in understanding their physical properties. However, calculations of the susceptibility for realistic strongly correlated compounds have not been realized due to the difficulty in numerical calculations. Applying data science approaches, this project has achieved important progress toward the realization of susceptibility calculations for strongly correlated compounds.

    In collaboration with the Medical Science team, Planetary Science team and others, we have developed image reconstruction methods from fewer numbers of measurement data in magnetic resonance imaging (MRI) and very long baseline interferometry (VLBI), in which compressed sensing has been utilized. As an example, using one of the proposed methods, we visualized spatio-temporal dynamics of metabolism of glucose injected into a tumor-bearing mouse in vivo via magnetic resonance spectroscopic imaging (MRSI), where one can observe spreading of the injected glucose over the whole body and conversion into lactate within the tumor tissue (the Warburg effect). Without compressed sensing, it takes several hours to acquire data even for a single frame, making measurement of spatio-temporal dynamics impossible. We have thus proved feasibility of the concept that with compressed sensing one can visualize spatio-temporal dynamics of biochemical processes in body non-invasively.

    Two achievements have been attained with regard to "the relationship between prime factorization and computational complexity" and "the use of non-trivial quantum fluctuation of quantum annealing" mentioned in the subjects of basic research B. For the former, the free energy shape is clarified by analyzing the structure of energy and entropy for prime number decomposition. The latter half of the result is a large progress that is never predicted, and even for non stoquastic systems that can not be simulated by the quantum Monte Carlo method in a straightforward way, the quantum Monte Carlo method can be implemented using an adaptive transverse magnetic field.

    We have studied the statistical-mechanics model of the prime factorization problem via a formulation of the ground-state searching problem. By the analysis of the density of states of two macroscopic quantities, i.e., the energy and the Hamming distance from the correct solutions, leads to two features that are each related to two marked changes in the energy region sampled via Monte Carlo simulation or simulated annealing. One is the peculiar first order phase transition that has the intermediate property between the conventional first-order transition and the second-order one and the other is the convex kink in the density of states.
