Rényi entropies and negative central charges in non-Hermitian quantum systems
Yi-Ting Tu, Yu-Chin Tzeng, Po-Yao Chang
Quantum entanglement is one essential element to characterize many-body quantum systems. However, the entanglement measures are mostly discussed in Hermitian systems. Here, we prop…

Non-Abelian fracton order from gauging a mixture of subsystem and global symmetries
Yi-Ting Tu, Po-Yao Chang
We demonstrate a general gauging procedure of a pure matter theory on a lattice with a mixture of subsystem and global symmetries. This mixed symmetry can be either a semidirect pr…
