Observation of topological phases without crystalline counterparts
Mou Yan, Yu-Liang Tao, Yichong Hu +4
Topological phases have been extensively studied primarily in crystalline systems with translational symmetry. Recent theoretical studies, however, have demonstrated the existence…

Quantized Thouless Pumping of Dark Solitons
Yu-Liang Tao, Huaxin He, Hao Lyu +2
Nonlinearity enables the emergence of localized waves such as solitons that maintain their shapes during propagation. Solitons are broadly classified into bright and dark solitons.…

Exact Model Reduction for Continuous-Time Open Quantum Dynamics
Tommaso Grigoletto, Yukuan Tao, Francesco Ticozzi +1
We consider finite-dimensional many-body quantum systems described by time-independent Hamiltonians and Markovian master equations, and present a systematic method for constructing…
