Bias in Local Spin Measurements from Deformed Symmetries
Michele Arzano, Goffredo Chirco, Jerzy Kowalski-Glikman
We study local spin measurements on bipartite singlet states when rotational symmetry is described by a quantum group rather than an ordinary Lie group. Although the fundamental sp…

Quantum Evolution of Hopf Algebra Hamiltonians
Michele Arzano, Antonio Del Prete, Domenico Frattulillo
In recent years, growing attention has been devoted to the possibility that theories with deformed symmetries, associated with certain models of non-commutative spacetime, may enco…

Operator Entanglement from Non-Commutative Symmetries
Michele Arzano, Goffredo Chirco
We argue that Hopf-algebra deformations of symmetries -- as encountered in non-commutative models of quantum spacetime -- carry an intrinsic content of th…
