Diagnosing Quantum Phases Using Long-Range Two-Site Quantum Resource Behaviors
Lin-Lin Su, Jun Ren, Wen-Long Ma +2
We propose and demonstrate that the behaviors of long-range, two-site quantum resources can effectively diagnose quantum phases. In an XX spin chain with symmetry-breaking quantum…

Attaining near-ideal Dicke superradiance in expanded spatial domains
Jun Ren, Shicheng Zhu, Z. D. Wang
Dicke superradiance is essentially a case of correlated dissipation leading to the macroscopic quantum coherence. Superradiance for arrays of inverted emitters in free space requir…
