Quantum batteries at the verge of a phase transition
(IOP, 2022)
Starting from the observation that the reduced state of a system strongly coupled to a bath is, in general, an athermal state, we introduce and study a cyclic battery-charger quantum device that is in thermal equilibrium, ...
Efficiency fluctuations in a quantum battery charged by a repeated interaction process
(MDPI, 2022)
A repeated interaction process assisted by auxiliary thermal systems charges a quantum battery. The charging energy is supplied by switching on and off the interaction between the battery and the thermal systems. The charged ...
Optimization and application of the quantum adiabatic theorem, and the quantum origin of classical interference
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-03-29)
In this master’s thesis, we developed three different topics. In the first topic, we studied the quantum adiabatic brachistochrone method (QAB) for optimizing adiabatic dynamics. In the first part of this study, we reported ...
New quantum technologies: batteries with qubits and electromagnetic resonators
(Universidad de Chile, 2021)
In this thesis, an emerging quantum technology is studied as an open quantum system: the
quantum battery (QB). This new technology has recently emerged as a promising tool for
the thermodynamic control at the quantum ...
Dissipative charging of a quantum battery
(2019)
We show that a cyclic unitary process can extract work from the thermodynamic equilibrium state of an engineered quantum dissipative process. Systems in the equilibrium states of these processes serve as batteries, storing ...
Dissipative Charging of a Quantum Battery
(American Physical Society, 2019)
© 2019 American Physical Society.We show that a cyclic unitary process can extract work from the thermodynamic equilibrium state of an engineered quantum dissipative process. Systems in the equilibrium states of these ...
Charging assisted by thermalization
(American Physical Society, 2020)
A system in thermal equilibrium with a bath will generally be in an athermal state, if the system-bath coupling
is strong. In some cases, it will be possible to extract work from that athermal state, after disconnecting ...
Nanoscale origins of super-capacitance phenomena
(2019-02-28)
We review the origins of capacitive phenomena at the nanoscale to demonstrate that electrochemistry cannot be understood without a critical re-reading of nanoscale electronics, and vice-versa. The fundamentals are stated ...
O efeito Zeno no controle da evolução adiabática de um sistema quântico a partir de medidas não-seletivas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2022-07-26)
The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting ...
