Nonreciprocal and Geometric Frustration in Dissipative Quantum Spins
Guitao Lyu, Myung-Joong Hwang
Nonreciprocal interactions often create conflicting dynamical objectives that cannot be simultaneously satisfied, leading to nonreciprocal frustration. On the other hand, geometric…

Floquet eigenspectra of a nonlinear two-mode system under periodic driving: the emergence of "ring" structures
Guitao Lyu, Lih-King Lim, Gentaro Watanabe
We study Floquet eigenspectra of a nonlinear two-mode system under a periodic driving of the off-diagonal coupling. By solving the Gross-Pitaevskii equation numerically, we obtain…
