This review focuses on the field of quantum entanglement applied to condensed matter
physics systems with strong correlations, a domain which has rapidly grown over the last …

A bstract We consider the form factor bootstrap approach of integrable field theories to
derive matrix elements of composite branch-point twist fields associated with symmetry …

We study the symmetry resolved entanglement entropies in gapped integrable lattice
models. We use the corner transfer matrix to investigate two prototypical gapped systems …

A bstract We generalise the form factor bootstrap approach to integrable field theories with U
(1) symmetry to derive matrix elements of composite branch-point twist fields associated with …

In this paper we continue the programme initiated in Part I, that is the study of entanglement
measures in the sine-Gordon model. In both parts, we have focussed on one specific …

A bstract In this paper, we apply the form factor bootstrap approach to branch point twist
fields in the q-state Potts model for q≤ 3. For q= 3 this is an integrable interacting quantum …

We present a detailed study of the fidelity, the entanglement entropy and the entanglement
spectrum, for a dimerized chain of spinless fermions—a simplified Su–Schrieffer–Heeger …

A bstract We study the Rényi entanglement entropies along the massless renormalisation
group flow that connects the tricritical and critical Ising field theories. Similarly to the massive …

We investigate the von Neumann entanglement entropy and Schmidt gap in the vortex-free
ground state of the Kitaev model on the honeycomb lattice for square/rectangular and …

We compute change in entanglement entropy for a single interval in the 1+ 1-dimensional
sine-Gordon model perturbatively in the coupling. The sine-Gordon perturbation can be …
