We construct Brownian Sachdev-Ye-Kitaev (SYK) chains subjected to continuous monitoring
and explore possible entanglement phase transitions therein. We analytically derive the …

Entanglement is one of the most important concepts in quantum physics. We review recent
progress in understanding the quantum entanglement in many-body systems using large-N …

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 …

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 …

A bstract In this work, we study the information scrambling and the entanglement dynamics
in the complex Brownian Sachdev-Ye-Kitaev (cBSYK) models, focusing on their …

Non-unitary evolution can give rise to novel steady states classified by their entanglement
properties. In this work, we aim to understand the effect of long-range hopping that decays …

Capacity of entanglement (CoE), an information-theoretic measure of entanglement, defined
as the variance of modular Hamiltonian, is known to capture the deviation from the maximal …

A bstract Thanks to their prominent collective character, long-range interactions promote
information spreading and generate forms of entanglement scaling, which cannot be …

This book presents the essential ideas of coherent states and provides researchers and
graduate students with the necessary tools for various applications of generalized coherent …

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 …
