Liouvillian gap closing--bound states in the continuum connection and diverse dynamics in a giant-atom waveguide QED setup
Hongwei Yu, Mingzhu Weng, Zhihai Wang +1
In open quantum systems, reduced dynamics is commonly described by a master equation, whose Liouvillian gap closing (LGC) typically signals the emergence of decoherence-free subspa…
Quantum Teleportation in Non-equilibrium Environments and Fixed-point Fidelity
Xiaokun Yan, Zhihai Wang, Kun Zhang +1
Quantum teleportation, a fundamental protocol in quantum information science, enables the transfer of quantum states through entangled particle pairs and classical communication ch…
Rabi oscillation and fractional population via the bound states in the continuum in a giant atom waveguide QED setup
Hongwei Yu, Xiaojun Zhang, Zhihai Wang +1
We study the dynamics of two giant atoms interacting with a coupled resonator waveguide (CRW) beyond the Markovian approximation. The distinct atomic configurations determine the n…
Driven-dissipative quantum battery with nonequilibrium reservoirs
Zhihai Wang, Hongwei Yu, Jin Wang
We investigate a quantum battery system under both external driving and dissipation. The system consists of a coupled two-level charger and battery immersed in nonequilibrium fermi…
