Particle Number Fluctuations, Rényi and Symmetry-resolved Entanglement Entropy in Two-dimensional Fermi Gas from Multi-dimensional Bosonization
Mao Tian Tan, Shinsei Ryu
In this paper, we revisit the computation of particle number fluctuations and the Rényi entanglement entropy of a two-dimensional Fermi gas using multi-dimensional bosonization. In…

Quantum vs. classical information: operator negativity as a probe of scrambling
Jonah Kudler-Flam, Masahiro Nozaki, Shinsei Ryu +1
We consider the logarithmic negativity and related quantities of time evolution operators. We study free fermion, compact boson, and holographic conformal field theories (CFTs) as…

Signature of quantum chaos in operator entanglement in 2d CFTs
Laimei Nie, Masahiro Nozaki, Shinsei Ryu +1
We study operator entanglement measures of the unitary evolution operators of (1+1)-dimensional conformal field theories (CFTs), aiming to uncover their scrambling and chaotic beha…
