Quantum geometric tensor away from Equilibrium
Davide Rattacaso, Alioscia Hamma, Patrizia Vitale
The manifold of ground states of a family of quantum Hamiltonians can be endowed with a quantum geometric tensor whose singularities signal quantum phase transitions and give a gen…
Nonlinear Dynamics from Linear Quantum Evolutions
Florio M. Ciaglia, Fabio Di Cosmo, Armando Figueroa +5
Linear dynamics restricted to invariant submanifolds generally gives rise to nonlinear dynamics. Submanifolds in the quantum framework may emerge for several reasons: one could be…
Lagrangian formulation for electric charge in a magnetic monopole distribution
G. Marmo, Emanuela Scardapane, A. Stern +2
We give a Lagrangian description of an electric charge in a field sourced by a continuous magnetic monopole distribution. The description is made possible thanks to a doubling of t…
Dichotomic probability representation of quantum states
Margarita A. Man'ko, Vladimir I. Man'ko, Giuseppe Marmo +2
We present systematic proofs of statements about probability representations of qudit density states in terms of standard probability distributions of dichotomic random variables.…
T-Duality and Doubling of the Isotropic Rigid Rotator
Francesco Bascone, Vincenzo Emilio Marotta, Franco Pezzella +1
After reviewing some of the fundamental aspects of Drinfel'd doubles and Poisson-Lie T-duality, we describe the three-dimensional isotropic rigid rotator on star…
T-Dualities and Doubled Geometry of the Principal Chiral Model
Vincenzo E. Marotta, Franco Pezzella, Patrizia Vitale
The Principal Chiral Model (PCM) defined on the group manifold of SU(2) is here investigated with the aim of getting a further deepening of its relation with Generalized and Double…
