Dynamically contracted algebra of observables for dissipative quantum systems
Sahar Alipour, Dariusz Chruściński, Paolo Facchi +3
A method is discussed to analyze the dynamics of a dissipative quantum system. The method hinges upon the definition of an alternative (time-dependent) product among the observable…
Tricriticalities and Quantum Phases in Spin-Orbit-Coupled Spin- Bose Gases
Giovanni I. Martone, Francesco V. Pepe, Paolo Facchi +2
We study the zero-temperature phase diagram of a spin-orbit-coupled Bose-Einstein condensate of spin , with equally weighted Rashba and Dresselhaus couplings. Depending on the a…
A shortcut through the Coulomb gas method for spectral linear statistics on random matrices
Fabio Deelan Cunden, Paolo Facchi, Pierpaolo Vivo
In the last decade, spectral linear statistics on large dimensional random matrices have attracted significant attention. Within the physics community, a privileged role has been p…
Moving Walls and Geometric Phases
Paolo Facchi, Giancarlo Garnero, Giuseppe Marmo +1
We unveil the existence of a non-trivial Berry phase associated to the dynamics of a quantum particle in a one dimensional box with moving walls. It is shown that a suitable choice…
A large-N approximated field theory for multipartite entanglement
P. Facchi, G. Florio, G. Parisi +2
We study the characterization of multipartite entanglement for the random states of an -qbit system. Unable to solve the problem exactly we generalize it, changing complex numbe…
Two-Mode Bosonic Quantum Metrology with Number Fluctuations
Antonella De Pasquale, Paolo Facchi, Giuseppe Florio +3
We search for the optimal quantum pure states of identical bosonic particles for applications in quantum metrology, in particular in the estimation of a single parameter for the ge…
