Integrable spin-1/2 Richardson-Gaudin XYZ models in an arbitrary magnetic field
Pieter W. Claeys, Claude Dimo, Stijn De Baerdemacker +1
We establish the most general class of spin-1/2 integrable Richardson-Gaudin models including an arbitrary magnetic field, returning a fully anisotropic (XYZ) model. The restrictio…
Richardson-Gaudin models and broken integrability
Pieter W. Claeys
This thesis presents an introduction to the class of Richardson-Gaudin integrable models, with special focus on the Bethe ansatz wave function, and investigates ways of applying th…
Something interacting and solvable in 1d
Eyzo Stouten, Pieter W. Claeys, Mikhail Zvonarev +2
We present a two-parameter family of exactly solvable quantum many-body systems in one spatial dimension containing the Lieb-Liniger model of interacting bosons as a particular cas…
Out-of-equilibrium phase transitions induced by Floquet resonances in a periodically quench-driven XY spin chain
Sergio Enrique Tapias Arze, Pieter W. Claeys, Isaac Pérez Castillo +1
We consider the dynamics of an XY spin chain subjected to an external transverse field which is periodically quenched between two values. By deriving an exact expression of the Flo…
Integrability and duality in spin chains
Eyzo Stouten, Pieter W. Claeys, Jean-Sébastien Caux +1
We construct a new, two-parametric family of integrable models and reveal their underlying duality symmetry. A modular subgroup of this duality is shown to connect non-interacting…
