Large barrier behaviour of the rate constant from the diffusion equation
Pierpaolo Pravatto, Barbara Fresch, Giorgio J. Moro
Many processes in chemistry, physics, and biology depend on thermally activated events in which the system changes its state by surmounting an activation barrier. Examples range fr…
The tunneling splitting and the Kramers theory of activated processes
Pierpaolo Pravatto, Barbara Fresch, Giorgio J. Moro
The study of tunneling splitting is fundamental to get insight into the dynamics of a multitude of molecular systems. In this paper, a novel approach to the analysis of the ground-…
Quantum computing for classical problems: Variational Quantum Eigensolver for activated processes
Pierpaolo Pravatto, Davide Castaldo, Federico Gallina +3
The theory of stochastic processes impacts both physical and social sciences. At the molecular scale, stochastic dynamics is ubiquitous because of thermal fluctuations. The Fokker-…
Signatures of Anderson localization and delocalized random quantum states
Giorgio J. Moro, Giulia DalľOsto, Barbara Fresch
We consider the notion of equilibration for an isolated quantum system exhibiting Anderson localization. The system is assumed to be in a pure state, i.e., described by a wave-func…
Pilot-wave quantum theory with a single Bohm's trajectory
Francesco Avanzini, Barbara Fresch, Giorgio J. Moro
The representation of a quantum system as the spatial configuration of its constituents evolving in time as a trajectory under the action of the wave-function, is the main objectiv…
Response of quantum pure states
Barbara Fresch, Giorgio J. Moro
The response of a quantum system in a pure state to an external force is investigated by reconsidering the standard statistical approach to quantum dynamics on the light of the sta…
