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…

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…
