Quantum-group-invariant models: Bethe ansatz and finite-size spectrum
Holger Frahm, Sascha Gehrmann, Rafael I. Nepomechie +1
We consider the quantum integrable spin chain models associated with the Jimbo R-matrix based on the quantum affine algebra , subject to quantum-group-invariant boun…
Preface to Fields, Gravity, Strings and Beyond: In Memory of Stanley Deser
Marc Henneaux, Rafael I. Nepomechie, Domenico Seminara
This is a preface to Fields, Gravity, Strings and Beyond, a special issue collection of articles published in J. Phys. A in memory of Stanley Deser.
Boundary reflection matrices of massive -perturbed unitary minimal models
Zoltan Bajnok, Rafael I. Nepomechie, Paul A. Pearce
We propose explicit expressions for the boundary reflection matrices of the series of massive scattering theories, obtained by perturbing the unitar…
symmetry of XX spin chains
Nicolas Crampé, Rafael I. Nepomechie, Luc Vinet +1
We show that, after suitably adjusting a uniform transverse magnetic field, the generic inhomogeneous open XX spin chain has a two-fold degeneracy, and an exact symmetry wh…
Simple ways of preparing qudit Dicke states
Noah B. Kerzner, Federico Galeazzi, Rafael I. Nepomechie
Dicke states are permutation-invariant superpositions of qubit computational basis states, which play a prominent role in quantum information science. We consider here two higher-d…
Entanglement of Inhomogeneous Free Bosons and Orthogonal Polynomials
Pierre-Antoine Bernard, Rafael I. Nepomechie, Gilles Parez +3
In this paper, we investigate the ground-state entanglement entropy in inhomogeneous free-boson models in one spatial dimension. We develop a powerful method to extract the leading…
