Integrable auxiliary field deformations of coset models
Mattia Cesàro, Axel Kleinschmidt, David Osten
We prove the existence of a family of integrable deformations of -coset models in two dimensions. Our approach uses and generalises the method of auxiliary fields tha…

Non-Lorentzian expansions of the Lorentz force and kinematical algebras
José Luis V. Cerdeira, Joaquim Gomis, Axel Kleinschmidt
We consider non-Lorentzian expansions, Galilean and Carrollian, of the Lorentz force equation in which both the particle position and the electro-magnetic field are expanded. There…
