Integrable models based on non-semi-simple groups and plane wave target spacetimes
Konstantinos Sfetsos, Konstantinos Siampos
We initiate the construction of integrable -deformed WZW models based on non-semisimple groups. We focus on the four-dimensional case whose underlying symmetries are based on th…
Dynamically restoring conformal invariance in (integrable) -models
Rigers Aliaj, Konstantinos Sfetsos, Konstantinos Siampos
Integrable -deformed -models are characterized by an underlying current algebra/coset model CFT deformed, at the infinitesimal level, by current/parafermion bilinears. We pro…
Relativistic Fluids, Hydrodynamic Frames and their Galilean versus Carrollian Avatars
Anastasios C. Petkou, P. Marios Petropoulos, David Rivera Betancour +1
We comprehensively study Galilean and Carrollian hydrodynamics on arbitrary backgrounds, in the presence of a matter/charge conserved current. For this purpose, we follow two disti…
