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…

The von Neumann algebraic quantum group and the DSSYK model
Koen Schouten, Mikhail Isachenkov
The double-scaling limit of the SYK (DSSYK) model is known to possess an underlying quantum group symmetry. In this paper, we provide, for the f…
