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…
Multicritical dissipative phase transitions in the anisotropic open quantum Rabi model
Guitao Lyu, Korbinian Kottmann, Martin B. Plenio +1
We investigate the nonequilibrium steady state of the anisotropic open quantum Rabi model, which exhibits first-order and second-order dissipative phase transitions upon varying th…
Topological Unwinding in an Exciton-Polariton Condensate Array
Guitao Lyu, Yuki Minami, Na Young Kim +2
The phase distribution in a Bose-Einstein condensate can realize various topological states classified by distinct winding numbers. While states with different winding numbers are…
Exciting the long-lived Higgs mode in superfluid Fermi gases with particle removal
Guitao Lyu, Kui-Tian Xi, Sukjin Yoon +2
Experimental evidence of the Higgs mode in strongly interacting superfluid Fermi gases had not been observed until recently [Behrle et al., Nat. Phys. 14, 781 (2018)]. Due to the c…
Persistent current by a static non-Hermitian ratchet
Guitao Lyu, Gentaro Watanabe
We propose a scheme to generate a persistent current in driven-dissipative systems which can be described by the generalized Gross-Pitaevskii (GP) equation. Our proposal consists o…
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…
