Multifractality in non-unitary random dynamics
Jason Iaconis, Xiao Chen
We explore the multifractality of the steady state wave function in non-unitary random quantum dynamics in one dimension. We focus on two classes of random systems: the hybrid Clif…
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…
Yang-Lee edge singularity triggered entanglement transition
Shao-Kai Jian, Zhi-Cheng Yang, Zhen Bi +1
We show that a class of symmetric non-Hermitian Hamiltonians realizing the Yang-Lee edge singularity exhibits an entanglement transition in the long-time steady stat…
Non-unitary dynamics of Sachdev-Ye-Kitaev chain
Chunxiao Liu, Pengfei Zhang, Xiao Chen
We construct a series of one-dimensional non-unitary dynamics consisting of both unitary and imaginary evolutions based on the Sachdev-Ye-Kitaev model. Starting from a short-range…
Subsystem Rényi Entropy of Thermal Ensembles for SYK-like models
Pengfei Zhang, Chunxiao Liu, Xiao Chen
The Sachdev-Ye-Kitaev model is an -modes fermionic model with infinite range random interactions. In this work, we study the thermal Rényi entropy for a subsystem of the SYK mod…
