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…

One-directional quantum mechanical dynamics and an application to decision making

Fabio Bagarello

In recent works we have used quantum tools in the analysis of the time evolution of several macroscopic systems. The main ingredient in our approach is the self-adjoint Hamiltonian…

Probing the non-Planckian spectrum of thermal radiation in a micron-sized cavity with a spin-polarized atomic beam

Giuseppe Bimonte

It is commonly thought that thermal photons with transverse electric polarization cannot exist in a planar metallic cavity whose size is smaller than the thermal wavelength $λ_…

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…

On the notion of composite system

Florio M. Ciaglia, Alberto Ibort, Giuseppe Marmo

The notion of composite system made up of distinguishable parties is investigated in the context of arbitrary convex spaces.

Groupoids and Coherent states

Fabio Di Cosmo, Alberto Ibort, Giuseppe Marmo

Schwinger's algebra of selective measurements has a natural interpretation in terms of groupoids. This approach is pushed forward in this paper to show that the theory of coherent…

A no-go result for the quantum damped harmonic oscillator

Fabio Bagarello, Francesco Gargano, Federico Roccati

In this letter we show that it is not possible to set up a canonical quantization for the damped harmonic oscillator using the Bateman lagrangian. In particular, we prove that no s…

On the Casimir effect between superconductors

Giuseppe Bimonte

A recent experiment [R. A. Norte et al. Phys. Rev. Lett. {\bf 121}, 030405 (2018)] probed the variation of the Casimir force between two closely spaced thin Al films, as they trans…

Improving quantum annealing of the ferromagnetic -spin model through pausing

G. Passarelli, V. Cataudella, P. Lucignano

The probability of success of quantum annealing can be improved significantly by pausing the annealer during its dynamics, exploiting thermal relaxation in a controlled fashion. In…
