Entanglement asymmetry in gauge theories: chiral anomaly in the finite temperature massless Schwinger model
Adrien Florio, Sara Murciano
The entanglement asymmetry has emerged in recent years as a practical quantity to study phases of matter. We present the first study of entanglement asymmetry in gauge theories by…
Entanglement asymmetry and symmetry defects in boundary conformal field theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
A state in a quantum system with a given global symmetry, , can be sensitive to the presence of boundaries, which may either preserve or break this symmetry. In this work, we in…
Symmetry resolution of the computable cross-norm negativity of two disjoint intervals in the massless Dirac field theory
Andrea Bruno, Filiberto Ares, Sara Murciano +1
We investigate how entanglement in the mixed state of a quantum field theory can be described using the cross-computable norm or realignment (CCNR) criterion, employing a recently…
An entanglement asymmetry study of black hole radiation
Filiberto Ares, Sara Murciano, Lorenzo Piroli +1
Hawking's discovery that black holes can evaporate through radiation emission has posed a number of questions that with time became fundamental hallmarks for a quantum theory of gr…
Symmetry-resolved Entanglement Entropy, Spectra & Boundary Conformal Field Theory
Yuya Kusuki, Sara Murciano, Hirosi Ooguri +1
We perform a comprehensive analysis of the symmetry-resolved (SR) entanglement entropy (EE) for one single interval in the ground state of a D conformal field theory (CFT), th…
Finite temperature negativity Hamiltonians of the massless Dirac fermion
Federico Rottoli, Sara Murciano, Pasquale Calabrese
The negativity Hamiltonian, defined as the logarithm of a partially transposed density matrix, provides an operatorial characterisation of mixed-state entanglement. However, so far…
Full counting statistics and symmetry resolved entanglement for free conformal theories with interface defects
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We consider the ground state of two species of one-dimensional critical free theories coupled together via a conformal interface. They have an internal global symmetry and w…
Entanglement resolution of free Dirac fermions on a torus
Alessandro Foligno, Sara Murciano, Pasquale Calabrese
Whenever a system possesses a conserved charge, the density matrix splits into eigenspaces associated to the each symmetry sector and we can access the entanglement entropy in a gi…
Rényi entropy and negativity for massless complex boson at conformal interfaces and junctions
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We consider the ground state of a theory composed by species of massless complex bosons in one dimension coupled together via a conformal interface. We compute both the Rényi e…
Symmetry-resolved Page curves
Sara Murciano, Pasquale Calabrese, Lorenzo Piroli
Given a statistical ensemble of quantum states, the corresponding Page curve quantifies the average entanglement entropy associated with each possible spatial bipartition of the sy…
Multi-charged moments of two intervals in conformal field theory
Filiberto Ares, Pasquale Calabrese, Giuseppe Di Giulio +1
We study the multi-charged moments for two disjoint intervals in the ground state of two dimensional CFTs with central charge and global symmetry: the massless D…
Rényi entropy and negativity for massless Dirac fermions at conformal interfaces and junctions
Luca Capizzi, Sara Murciano, Pasquale Calabrese
We investigate the ground state of a (1+1)-dimensional conformal field theory built with species of massless free Dirac fermions coupled at one boundary point via a conformal j…
Generalized entanglement entropies in two-dimensional conformal field theory
Sara Murciano, Pasquale Calabrese, Robert M. Konik
We introduce and study generalized Rényi entropies defined through the traces of products of where are eigenstates of a two-dim…
Symmetry-resolved entanglement entropy in Wess-Zumino-Witten models

We consider the problem of the decomposition of the Rényi entanglement entropies in theories with a non-abelian symmetry by doing a thorough analysis of Wess-Zumino-Witten (WZW) mo…

We present a thorough analysis of the entanglement entropies related to different symmetry sectors of free quantum field theories (QFT) with an internal U(1) symmetry. We provide e…
