Measurement induced scrambling and emergent symmetries in random circuits
Haifeng Tang, Hong-Yi Wang, Zhong Wang +1
Quantum entanglement is affected by unitary evolution, which spreads the entanglement through the whole system, and also by measurements, which usually tends to disentangle subsyst…

Fragile non-Bloch spectrum and unconventional Green's function
Fei Song, Hong-Yi Wang, Zhong Wang
In non-Hermitian systems, it is a counterintuitive feature of the non-Hermitian skin effect (NHSE) that the energy spectrum and eigenstates can be totally different under open or p…

Non-Bloch PT symmetry breaking: Universal threshold and dimensional surprise
Fei Song, Hong-Yi Wang, Zhong Wang
In the presence of non-Hermitian skin effect, non-Hermitian lattices generally have complex-valued eigenenergies under periodic boundary condition, but they can have non-Bloch PT s…
