Geometric phase in dissipative quantum batteries
Camila Cristiano, Ludmila Viotti, Paula I. Villar
We study the geometric phase accumulated during non-adiabatic charging of different driven open quantum systems serving as quantum battery models. We provide a full numerical analy…
Geometric Phase of a Transmon in a Dissipative Quantum Circuit
Ludmila Viotti, Fernando C. Lombardo, Paula I. Villar
Superconducting circuits reveal themselves as promising physical devices with multiple uses. Within those uses, the fundamental concept of the geometric phase accumulated by the st…
Geometric Phases in Open Quantum Systems: Analysis and Applications
Ludmila Viotti
This thesis consists of several studies performed over different few-dof quantum systems exposed to the effect of an uncontrolled environment. The primary focus of the work is to e…
Geometric phases along quantum trajectories
Ludmila Viotti, Ana Laura Gramajo, Paula I. Villar +2
A monitored quantum system undergoing a cyclic evolution of the parameters governing its Hamiltonian accumulates a geometric phase that depends on the quantum trajectory followed b…
Geometric phase in a dissipative Jaynes-Cummings model: theoretical explanation for resonance robustness
Ludmila Viotti, Fernando C. Lombardo, Paula I. Villar
We follow a generalized kinematic approach to compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models, which provide a fully quantum descriptio…
Detectable Signature of Quantum Friction on a Sliding Particle in Vacuum
Fernando C. Lombardo, Ricardo S. Decca, Ludmila Viotti +1
Spatially separated bodies in relative motion through vacuum experience a tiny friction force known as quantum friction. This force has so far eluded experimental detection due to…
Enhanced decoherence for a neutral particle sliding on a metallic surface in vacuum
Ludmila Viotti, Fernando C. Lombardo, Paula I. Villar
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…
Boundary-induced effect encoded in the corrections to the geometric phase acquired by a bipartite two-level system
Ludmila Viotti, Fernando C. Lombardo, Paula I. Villar
We present a bipartite two-level system coupled to electromagnetic quantum vacuum fluctuations through a general dipolar coupling. We derive the master equation in the framework of…
Thermal corrections to quantum friction and decoherence: a Closed-Time-Path approach to atom-surface interaction
Ludmila Viotti, M. Belén Farías, Paula I. Villar +1
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-…
