Genuine quantum correlations in quantum many-body systems: a review of recent progress
Gabriele De Chiara, Anna Sanpera
Quantum information theory has considerably helped in the understanding of quantum many-body systems. The role of quantum correlations and in particular, bipartite entanglement, ha…
Entanglement scaling at first order phase transitions
A. Yuste, C. Cartwright, G. De Chiara +1
First order quantum phase transitions (1QPTs) are signaled, in the thermodynamic limit, by discontinuous changes in the ground state properties. These discontinuities affect expect…
A self-contained quantum harmonic engine
Brendan Reid, Simon Pigeon, Mauro Antezza +1
We propose a system made of three quantum harmonic oscillators as a compact quantum engine for producing mechanical work. The three oscillators play respectively the role of the ho…
Global and local thermometry schemes in coupled quantum systems
Steve Campbell, Mohammad Mehboudi, Gabriele De Chiara +1
We study the ultimate bounds on the estimation of temperature for an interacting quantum system. We consider two coupled bosonic modes that are assumed to be thermal and using quan…
Non-equilibrium quantum thermodynamics in Coulomb crystals
F. Cosco, M. Borrelli, P. Silvi +2
We present an in-depth study of the non-equilibrium statistics of the irreversible work produced during sudden quenches in proximity to the structural linear-zigzag transition of i…
Cavity assisted measurements of heat and work in optical lattices
Louis Villa, Gabriele De Chiara
We propose a method to experimentally measure the internal energy of a system of ultracold atoms trapped in optical lattices by coupling them to the fields of two optical cavities.…
Magnetic phases of spin-1 lattice gases with random interactions
Kenneth D. McAlpine, Simone Paganelli, Sergio Ciuchi +2
A spin-1 atomic gas in an optical lattice, in the unit-filling Mott Insulator (MI) phase and in the presence of disordered spin-dependent interaction, is considered. In this regime…
