Kick-induced rectified current in symmetric nano-electromechanical shuttle
Pinquan Qin, Hee Chul Park
We have studied the rectified current in a geometrically symmetric nano-electromechanical shuttle with periodic kicks and sinusoidal ac bias voltages. The rectified current is exac…
Anderson localization in generalized discrete time quantum walks
I. Vakulchyk, M. V. Fistul, P. Qin +1
We study Anderson localization in a generalized discrete time quantum walk - a unitary map related to a Floquet driven quantum lattice. It is controlled by a quantum coin matrix wh…
Interacting ultracold atomic kicked rotors: dynamical localization ?
Pinquan Qin, Alexei Andreanov, Hee Chul Park +1
We study the fate of dynamical localization of two quantum kicked rotors with contact interaction. This interaction mimics experimental realizations with ultracold atomic gases. Dy…
Dynamical Anderson transition in one-dimensional periodically kicked incommensurate lattices
Pinquan Qin, Chuanhao Yin, Shu Chen
We study the dynamical localization transition in a one-dimensional periodically kicked incommensurate lattice, which is created by perturbing a primary optical lattice periodicall…
Complexity and instability of quantum motion near a quantum phase transition
Pinquan Qin, Wen-ge Wang, Giuliano Benenti +1
We show that the number of harmonics of the Wigner function, recently proposed as a measure of quantum complexity, can be also used to characterize quantum phase transitions. The n…
Semiclassical approach to the quantum Loschmidt echo in deep quantum regions: from validity to breakdown
Pinquan Qin, Qian Wang, Wen-ge Wang
Semiclassical results are usually expected to be valid in the semiclassical regime. An interesting question is, in models in which appropriate effective Planck constants can be int…
Scaling behavior for a class of quantum phase transitions
Wen-ge Wang, Pinquan Qin, Qian Wang +2
We show that for quantum phase transitions with a single bosonic zero mode at the critical point, like the Dicke model and the Lipkin-Meshkov-Glick model, metric quantities such as…
Semiclassical Approach to Survival Probability at Quantum Phase Transitions
Wen-ge Wang, Pinquan Qin, Lewei He +1
We study the decay of survival probability at quantum phase transitions (QPT). The semiclassical theory is found applicable in the vicinities of critical points with infinite degen…
