Decoherence and discrete symmetries in deformed relativistic kinematics

Decoherence and discrete symmetries in deformed relativistic kinematics

Models of deformed Poincaré symmetries based on group valued momenta have long been studied as effective modifications of relativistic kinematics possibly capturing quantum gravity effects. In this contribution we show how they naturally lead to a generalized quantum time evolution of the type propo...
