Distance to integrability and complexity
Sean Casey, Marius de Leeuw, Tristan McLoughlin +1
We consider nearest-neighbour interactions on spin-1/2 chains. We find the full set of integrable models of this form and apply a numerical algorithm to determine the "closest" int…
Constrained integrability and anyonic chains
Matthew Blakeney, Luke Corcoran, Marius de Leeuw
We review the notion of Yang-Baxter integrability for spin chains that have Hilbert spaces with constraints, such as a Rydberg blockade. We focus on anyonic chains, whose constrain…
The quantum group structure of long-range integrable deformations
Koen Schouten, Marius de Leeuw
Quantum integrable spin chains are known to possess a large family of long-range deformations generated by the local, boost and bilocal operators. Although these deformations are w…
On deforming and breaking integrability
Ysla F. Adans, Marius de Leeuw, Tristan McLoughlin
In this paper we study nearest-neighbour deformations of integrable models. After expanding in the deformation parameter, we identify four possible types of deformations. First the…
