Dynamical characterization of topological phases beyond the minimal models
Xi Wu, Panpan Fang, Fuxiang Li
Dynamical characterization of topological phases under quantum quench dynamics has been demonstrated as a powerful and efficient tool. Previous studies have been focused on systems…
Full investigation of nonadiabatic dynamical characterization in arbitrary quenching process
Panpan Fang, Xinwei Shi, Yi-Xiang Wang +1
Recently, dynamical characterization of bulk topology has been experimentally realized under nonadiabatic sudden quench dynamics. However, it has been shown that only the topology…
Generic theory of characterizing topological phases under quantum slow dynamics
Panpan Fang, Yi-Xiang Wang, Fuxiang Li
Dynamical characterization of equilibrium topological phases has attracted considerable attention in recent years. In this paper, we make a thorough exploration of the non-adiabati…
Emergent topology under slow non-adiabatic quantum dynamics
Junchen Ye, Fuxiang Li
Characterization of equilibrium topological quantum phases by non-equilibrium quench dynamics provides a novel and efficient scheme in detecting topological invariants defined in e…
Phase Diagram of the Dynamics of a Precessing Qubit under Quantum Measurement
Xinru Tang, Fuxiang Li
We study the phase transitions induced by sequentially measuring a single qubit precessing under an external transverse magnetic field. Under projective quantum measurement, the pr…
Quantum annealing and thermalization: insights from integrability
Fuxiang Li, V. Y. Chernyak, N. A. Sinitsyn
We solve a model that has basic features that are desired for quantum annealing computations: entanglement in the ground state, controllable annealing speed, ground state energy se…
Dynamic Symmetries and Quantum Nonadiabatic Transitions
Fixiang Li, Nikolai A. Sinitsyn
Kramers degeneracy theorem is one of the basic results in quantum mechanics. According to it, the time-reversal symmetry makes each energy level of a half-integer spin system at le…
