Quantum error as an emergent magnetic field
Shao-Kai Jian, Chunxiao Liu, Xiao Chen +2
We investigate the effect of quantum errors on a monitored Brownian Sachdev-Ye-Kitaev (SYK) model featuring a measurement-induced phase transition that can be understood as a symme…
Universal Entanglement Transitions of Free Fermions with Long-range Non-unitary Dynamics
Pengfei Zhang, Chunxiao Liu, Shao-Kai Jian +1
Non-unitary evolution can give rise to novel steady states classified by their entanglement properties. In this work, we aim to understand its interplay with long-range hopping tha…
Emergent Replica Conformal Symmetry in Non-Hermitian SYK Chains
Pengfei Zhang, Shao-Kai Jian, Chunxiao Liu +1
Recently, the steady states of non-unitary free fermion dynamics are found to exhibit novel critical phases with power-law squared correlations and a logarithmic subsystem entangle…
