In this review we describe our current understanding of the properties of open string
tachyons on an unstable D-brane or brane–antibrane system in string theory. The various …

A review of Boundary and defect conformal field theory: open problems and applications,
following a workshop held at Chicheley Hall, Buckinghamshire, UK, 7–8 Sept. 2017. We …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …

Solitons emerge in various non-linear systems as stable localized configurations, behaving
in many ways like particles, from non-linear optics and condensed matter to nuclear physics …

This paper is a direct continuation of 1 where we began the study of the integrable structures
in Conformal Field Theory. We show here how to construct the operators \bfQ_±(λ) which act …

We describe the nature of charge transport at nonzero temperatures (T) above the two-
dimensional (d) superfluid-insulator quantum-critical point. We argue that the transport is …

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

The conductance for tunneling through an impurity in a Luttinger liquid is described by a
universal scaling function. We compute this scaling function exactly, by using the …

We have recently calculated exact nonequilibrium quantum transport properties through a
point contact in a Luttinger liquid. Using a particular quasiparticle basis of the Hilbert space …

A classical particle moving in a periodic potential can localize inside a single potential
minimum, but a quantum particle forms extended states by tunnelling to neighbouring …
