Deconfined quantum critical point in a dissipative spin-1/2 chain
Longye Lu, Shifeng Cui, Wenan Guo
Open quantum spin systems offer a previously unexplored route to realizing deconfined quantum criticality. We consider a spin-1/2 - chain, consisting of an antiferromagneti…

Detecting underlying symmetry-protected topological phases via strange correlators and edge engineering
Zhe Wang, Longye Lu, Shang-Qiang Ning +4
The vast majority of symmetry-protected topological (SPT) states are difficult to detect, which often leads to their misidentification as ordinary or topologically trivial phases.…

Tuning Topological States by Dissipation
Xue-Ping Ren, Yue Hu, Long-Ye Lu +4
The bulk-boundary correspondence plays a crucial role in topological quantum systems, however,this principle is broken in non-Hermitian systems. The breakdown of the bulk-boundary…
