Dynamical scaling laws in the quantum -state clock chain
Jia-Chen Tang, Wen-Long You, Myung-Joong Hwang +1
We show that phase transitions in the quantum -state clock model for can be characterized by an enhanced decay behavior of the Loschmidt echo via a small quench. The…
Spin Josephson effects of spin-orbit-coupled Bose-Einstein condensates in a non-Hermitian double well
Jia Tang, Zhou Hu, Zhao-Yun Zeng +5
In this paper, we investigate the spin and tunneling dynamics of a spin-orbit-coupled noninteracting Bose-Einstein condensate in a periodically driven non-Hermitian double-well pot…
Dynamical scaling of Loschmidt echo in non-Hermitian systems
Jia-Chen Tang, Su-Peng Kou, Gaoyong Sun
We show that non-Hermitian biorthogonal many-body phase transitions can be characterized by the enhanced decay of Loschmidt echo. The quantum criticality is numerically investigate…
Biorthogonal quantum criticality in non-Hermitian many-body systems
Gaoyong Sun, Jia-Chen Tang, Su-Peng Kou
We develop the perturbation theory of the fidelity susceptibility in biorthogonal bases for arbitrary interacting non-Hermitian many-body systems with real eigenvalues. The quantum…
Determining the twist in an optical fiber
Rakesh, Jiahua Tang, Andrew A Lacey
We determine the twist in a birefringent optical fiber from measurements, at one end of the fiber, of the fiber response to an impulsive source at the same end. This is the inverse…
