    We theoretically explained the experimentally observed stochastic switching (“p-bit” characteristics) of the Ising pseudo-spin of parametrically excited spin waves formed at room temperature. We explained it based on an instability of the uniform magnetization precession in the nonlinear regime which was published as Phys. Rev. B 105, 054403 (2022). We also predicted a dynamical phase of the parametrically excited magnons, which at lower temperatures is quantum correlated with significant distillible magnon entanglement useful for quantum information [arXiv:2111.00365]. These results on the nonlinear parametrically excited magnons can lead to unconventional computing schemes that may supersede conventional computing paradigms. <BR> I have also formed several experimental collaborations on nonlinearity of magnons and have developed theory for several recent experimental observations [e.g. arXiv:2201.10889]. For example, I have explained a reduction in dissipation of the uniform spin wave mode as a result of its three-magnon instability to a pair of magnons with low dissipation rates, which has been observed by Prof. Eiji Saitoh group (Univ. of Tokyo) [manuscript in preparation].

    The nonlinearity of spin waves in the context of microwave cavity magnonic was finalized and the findings were presented to the community at SPICE workshop in Mainz (2018) and Max-Planck Light in Erlangen (2018). The corresponding manuscript is in its final iterations between the authors M. Elyasi, Ya. M. Blanter and G. E. W. Bauer, and is soon to be submitted to a high impact factor journal. The results map out the steady states features, such as entanglement and nonclassicality, in the nonlinear phase space of the strongly driven cavity photon-magnon polaritons, using classical (from solution of stochastic equations of motion) and quantum mechanical (from solution of master equations) analysis and computation. The findings pave the way for implementing spin waves in quantum information. The other parallel direction considering nonlinearities in a topologically nontrivial spin lattice equivalent of Haldane model for magnons, led to a complete classification of self-localized spin wave modes, i.e. solitons, in static and dynamic configurations of the lattice. A unique observed feature was a nonlinearity induced topological phase change from nontrivial to trivial by increasing the power of soliton. The reason for this phase change was investigated and formed an important part of the study, which was published as Phys. Rev. B 99, 134402 (2019).
