All 4 x 4 solutions of the quantum Yang-Baxter equation
Marius de Leeuw, Vera Posch
In this paper, we complete the classification of 4 x 4 solutions of the Yang-Baxter equation. Regular solutions were recently classified and in this paper we find the remaining non…
Integrable Conformal Defects in N=4 SYM
Marius de Leeuw, Adolfo Holguin
In this paper we classify integrable conformal defects in N=4 SYM theory for which the scalar fields pick up a non-trivial vacuum expectation value. Defects of this form correspond…
Integrable models on Rydberg atom chains
Luke Corcoran, Marius de Leeuw, Balázs Pozsgay
We initiate a systematic study of integrable models for spin chains with constrained Hilbert spaces; we focus on spin-1/2 chains with the Rydberg constraint. We extend earlier resu…
A perturbative approach to the non-relativistic string spectrum
Marius de Leeuw, Andrea Fontanella, Juan Miguel Nieto García
In this letter we use a perturbative approach to find the spectrum of non-relativistic strings in the String Newton-Cartan (SNC) AdSS spacetime. We perturb the bosoni…
