Mixed-state fidelity and quantum criticality at finite temperature
Paolo Zanardi, H. T. Quan, Xiaoguang Wang +1
We extend to finite temperature the fidelity approach to quantum phase transitions (QPTs). This is done by resorting to the notion of mixed-state fidelity that allows one to compar…
Novel quantum phases of dipolar Bose gases in optical lattices
S. Yi, T. Li, C. P. Sun
We investigate the quantum phases of polarized dipolar Bosons loaded into a two-dimensional square and three-dimensional cubic optical lattices. We show that the long-range and ani…
Quantum Thermodynamic Cycles and quantum heat engines
H. T. Quan, Yu-xi Liu, C. P. Sun +1
In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum vers…
Controllable Coupling between Flux Qubit and Nanomechanical Resonator by Magnetic Field
Fei Xue, Y. D Wang, C. P. Sun +3
We propose an active mechanism for coupling the quantized mode of a nanomechanical resonator to the persistent current in the loop of a superconducting Josephson junction (or phase…
Peierls distorted chain as a quantum data bus for quantum state transfer
M. X. Huo, Ying Li, Z. Song +1
We systematically study the transfer of quantum state of electron spin as the flying qubit along a half-filled Peierls distorted tight-binding chain described by the Su-Schrieffer-…
Universal role of correlation entropy in critical phenomena
Shi-Jian Gu, Chang-Pu Sun, Hai-Qing Lin
In statistical physics, if we successively divide an equilibrium system into two parts, we will face a situation that, within a certain length , the physics of a subsystem is no…
