MB Farías, FC Lombardo, A Soba, PI Villar… - npj Quantum …, 2020 - nature.com
The geometric phase can be used as a fruitful venue of investigation to infer features of the
quantum systems. Its application can reach new theoretical frontiers and imply innovative …

Microscopic dynamical Casimir effect

RM Souza, F Impens, PAM Neto - Physical Review A, 2018 - APS
We consider an atom in its ground state undergoing a nonrelativistic oscillation in free
space. The interaction with the electromagnetic quantum vacuum leads to two effects to …

Quantum friction between graphene sheets

MB Farias, CD Fosco, FC Lombardo, FD Mazzitelli - Physical Review D, 2017 - APS
We study the Casimir friction phenomenon in a system consisting of two flat, infinite, and
parallel graphene sheets, which are coupled to the vacuum electromagnetic (EM) field …

Quantum friction in arbitrarily directed motion

J Klatt, MB Farías, DAR Dalvit, SY Buhmann - Physical Review A, 2017 - APS
Quantum friction, the electromagnetic fluctuation-induced frictional force decelerating an
atom which moves past a macroscopic dielectric body, has so far eluded experimental …

Thermal corrections to quantum friction and decoherence: A closed-time-path approach to atom-surface interaction

L Viotti, M Belén Farías, PI Villar, FC Lombardo - Physical Review D, 2019 - APS
In this paper we study the dissipative effects and decoherence induced on a particle moving
at constant speed in front of a dielectric plate in quantum vacuum, developing a closed-time …

Instantaneous and dynamical decoherence

J Polonyi - Journal of Physics A: Mathematical and Theoretical, 2018 - iopscience.iop.org
Two manifestations of decoherence, called instantaneous and dynamical, are investigated.
The former reflects the suppression of the interference between the components of the …

Open quantum systems' decay across time

J Klatt, CM Kropf, SY Buhmann - Physical Review Letters, 2021 - APS
The description of an open quantum system's decay almost always requires several
approximations so as to remain tractable. In this Letter, we first revisit the meaning, domain …

Motion-driven quantum dissipation in an open electronic system with nonlocal interaction

Y Wang, R Zhang, F Liu - arXiv preprint arXiv:2408.13163, 2024 - arxiv.org
In this paper, we study excitations and dissipation in two infinite parallel metallic plates with
relative motion. We model the degrees of freedom of the electrons in both plates using the …

Enhanced decoherence for a neutral particle sliding on a metallic surface in vacuum

L Viotti, FC Lombardo, PI Villar - Physical Review A, 2021 - APS
Bodies in relative motion, spatially separated in vacuum, experience a tiny friction force
known as quantum friction. This force has eluded experimental detection so far due to its …

Geometric phase corrections on a moving particle in front of a dielectric mirror

FC Lombardo, PI Villar - Europhysics Letters, 2017 - iopscience.iop.org
We consider an atom (represented by a two-level system) moving in front of a dielectric
plate, and study how traces of dissipation and decoherence (both effects induced by vacuum …
