We consider the symmetry resolved Rényi entropies in the one dimensional tight binding
model, equivalent to the spin-1/2 XX chain in a magnetic field. We exploit the generalised …

We study the symmetry resolved entanglement entropies in one-dimensional systems with
boundaries. We provide some general results for conformal invariant theories and then …

We investigate the symmetry resolution of entanglement in the presence of long-range
couplings. To this end, we study the symmetry-resolved entanglement entropy in the ground …

A bstract 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 …

We reconsider the computation of the entanglement entropy of two disjoint intervals in a (1+
1) dimensional conformal field theory by conformal block expansion of the 4-point …

We obtain a formula for the determinant of a block Toeplitz matrix associated with a
quadratic fermionic chain with complex coupling. Such couplings break reflection symmetry …

We study entanglement properties in a nonequilibrium steady state of a free-fermion chain,
that emerges after connecting two half-chains prepared at different temperatures. The …

A bstract We investigate the Rényi entanglement entropies for the one-dimensional
massless free boson compactified on a circle, which describes the low energy sector of …

The analysis of the entanglement entropy of a subsystem of a one-dimensional quantum
system is a powerful tool for unravelling its critical nature. For instance, the scaling …

We study the ground state entanglement entropy of the quantum Dyson hierarchical spin
chain in which the interaction decays algebraically with the distance as. We exploit the real …
