Accelerating Relaxation Dynamics in Open Quantum System with Liouvillian Skin Effect
Zeqing Wang, Yao Lu, Yi Peng +3
We investigate a non-Hermitian model featuring non-reciprocal gradient hoppings. Through an in-depth analysis of the Liouvillian spectrum and dynamics, we confirm the emergence of…
Absence of Correlations in Dissipative Interacting Qubits: a No-Go Theorem
Zeqing Wang, Ran Qi, Yao Lu +2
Exact solutions of model problems are elusive but potent tools for understanding many body interacting systems. We study a system of dissipative qubits with the Heisenberg interact…
Solutions of the Schrödinger equation for anisotropic dipole-dipole interaction plus isotropic van der Waals interaction
Ruijie Du, Ran Qi, Peng Zhang
By generalizing Bo Gao's approach [Phys. Rev. A 58, 1728 (1998)] for solving the Schrödinger equation for an isotropic van der Waals (vdW) potential to the systems with a multi-sca…
Exact Solutions and Quantum Defect Theory for van der Waals Potentials in Ultracold Molecular Systems
Jianwen Jie, Shi Chen, Yue Chen +1
In this paper, we have provided exact two-body solutions to the 2D and 3D Schrödinger equations with isotropic van der Waals potentials of the form \(\pm 1/r^6\). Based on these so…
Maximum Energy Growth Rate in Dilute Quantum Gases
Ran Qi, Zhe-yu Shi, Hui Zhai
In this letter we study how fast the energy density of a quantum gas can increase in time, when the inter-atomic interaction characterized by the -wave scattering length $a_\tex…
Interacting Bose gas across a narrow Feshbach resonance
Fan Yang, Ran Qi
We use a two-channel model to investigate an interacting Bose gas across a narrow Feshbach resonance within a field path integral approach. The ground state properties show strong…
