Oscillating bound states in waveguide-QED system with two giant atoms
F. J. Lü, W. Z. Jia
We study the bound states in the continuum (BIC) in a system of two identical two-level giant atoms coupled to a one-dimensional waveguide. By deriving general dark-state condition…

Simulating and probing many-body quantum states in waveguide-QED systems with giant atoms
C. L. Yang, W. Z. Jia
Waveguide quantum electrodynamics (wQED) with giant atoms provides a distinctive opportunity to study one-dimensional (1D) coupled spin systems through its unique decoherence-free…

Engineering photonic band gaps with a waveguide-QED structure containing an atom-polymer array
M. S. Wang, W. Z. Jia
We investigate the generation and engineering of photonic band gaps in waveguide quantum electrodynamics systems containing periodically arranged atom-polymers. We first consider t…
