Anatomy of Non-Hermitian Dynamical Quantum Phase Transitions
Yongxu Fu, Gao Xianlong
We establish a unified framework for dynamical quantum phase transitions (DQPTs) in non-Hermitian systems that encompasses both biorthogonal and self-norm non-biorthogonal formulat…
Effects of reservoir squeezing on the amplification of quantum correlation
Zhaorui Peng, Lucas C. Céleri, Abdul Basit +1
The dynamics of quantum discord is studied in a system of two identical noninteracting qubits coupled to a common squeezed vacuum bath through non-demolition interactions. We conce…
Persisting quantum effects in the anisotropic Rabi model at thermal equilibrium
He-Guang Xu, V. Montenegro, Gao Xianlong +2
Quantum correlations and nonclassical states are at the heart of emerging quantum technologies. Efforts to produce long-lived states of such quantum resources are a subject of tire…
Adiabatic-impulse approximation in non-Hermitian Landau-Zener Model
Xianqi Tong, Gao Xianlong, Su-peng Kou
We investigate the transition from PT-symmetry to PT-symmetry breaking and vice versa in the non-Hermitian Landau-Zener (LZ) models. The energy is generally complex, so the relaxat…
