Bias in Local Spin Measurements from Deformed Symmetries
Michele Arzano, Goffredo Chirco, Jerzy Kowalski-Glikman
The paper investigates how local spin measurements on entangled singlet states are affected when rotational symmetry is modeled by a quantum group, showing that conventional and br…

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…
