Symmetry Resolved Entanglement Entropy in a Non-Abelian Fractional Quantum Hall State
Mark J. Arildsen, Valentin Crépel, Nicolas Regnault +1
Symmetry-resolved entanglement entropy provides a powerful framework for probing the internal structure of quantum many-body states by decomposing entanglement into contributions f…

Rényi entropies for one-dimensional quantum systems with mixed boundary conditions
Benoit Estienne, Yacine Ikhlef, Andrei Rotaru
We present a general method for calculating Rényi entropies in the ground state of a one-dimensional critical system with mixed open boundaries, for an interval starting at one of…

Entanglement Entropy and Cauchy-Hadamard Renormalization
Benoit Estienne, Jiasheng Lin
This note presents a purely geometric construction of the so-called twist-field correlation functions in Conformal Field Theory (CFT), derived from conical singularities. This appr…
