Quantum criticality in the nonunitary dynamics of -dimensional free fermions
Qicheng Tang, Xiao Chen, W. Zhu
We explore the nonunitary dynamics of -dimensional free fermions and show that the obtained steady state is critical regardless the strength of the nonunitary evolution. Num…
Critical Scaling Behaviors of Entanglement Spectra
Qicheng Tang, W. Zhu
We investigate the evolution of entanglement spectra under a global quantum quench from a short-range correlated state to the quantum critical point. Motivated by the conformal map…
Measurement-induced phase transition: A case study in the non-integrable model by density-matrix renormalization group calculations
Qicheng Tang, W. Zhu
We study the effect of local projective measurements on the quantum quench dynamics. As a concrete example, a one-dimensional Bose-Hubbard model is simulated by the matrix product…
Out-of-time-order correlators and quantum phase transitions in the Rabi and Dicke model
Zheng-Hang Sun, Jia-Qi Cai, Qi-Cheng Tang +2
The out-of-time-order correlators (OTOCs) is used to study the quantum phase transitions (QPTs) between the normal phase and the superradiant phase in the Rabi and few-body Dicke m…
Influence of hydrogen on electron-phonon coupling and intrinsic electrical resistivity in zirconium: a first-principles study
Qicheng Tang, L. A. Svyatkin, I. P. Chernov
The paper presents the first-principle calculation of the electron-phonon coupling and the temperature dependence of the intrinsic electrical resistivity of the zirconium-hydrogen…
