A Stochastic Origin of Spacetime Non-Commutativity
Michele Arzano, Folkert Kuipers
We propose a stochastic interpretation of spacetime non-commutativity starting from the path integral formulation of quantum mechanical commutation relations. We discuss how the (n…
Infrared gravity and a celestial obstruction to monogamy constraints
Francesco Alessio, Michele Arzano
We argue that gravitational interactions between particles require a departure from the conventional picture of the quantum state of a multiparticle system in terms of tensor produ…
Entanglement entropy and horizon temperature in conformal quantum mechanics
Michele Arzano, Alessandra D'Alise, Domenico Frattulillo
The generators of radial conformal symmetries in Minkowski space-time can be put in correspondence with generators of time evolution in conformal quantum mechanics. Within this cor…
A new pairwise boost quantum number from celestial states
Francesco Alessio, Michele Arzano
Infrared effects in the scattering of particles in gravity and electrodynamics entail an exchange of relativistic angular momentum between pairs of particles and the gauge field. D…
Entanglement entropy in conformal quantum mechanics
Michele Arzano, Alessandra D'Alise, Domenico Frattulillo
We consider sets of states in conformal quantum mechanics associated to generators of time evolution whose orbits cover different regions of the time domain. States labelled by a c…
Quantum particles in non-commutative space-time: an identity crisis
Michele Arzano, Jerzy Kowalski-Glikman
We argue that the notion of identical particles is no longer well defined in quantum systems governed by non-commutative deformations of space-time symmetries. Such models are char…
