Adiabatic quantum games and phase-transition-like behavior between optimal strategies
(2018-06-01)
In this paper we propose a game of a single qubit whose strategies can be implemented adiabatically. In addition, we show how to implement the strategies of a quantum game through controlled adiabatic evolutions, where we ...
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 ...
Analysis of Entropy trajectories in very Heavy Fermions for Adiabatic Demagnetization Refrigeration at the T<1K range
(Elsevier, 2019)
With the aim to improve classical paramagnetic salts performances for adiabatic magnetization refrigeration processes, relevant thermodynamic parameters of recently discovered very heavy fermion Yb-based intermetallic ...
Decoherence in current induced forces: Application to adiabatic quantum motors
(American Physical Society, 2015-08)
Current induced forces are not only related with the discrete nature of electrons but also with its quantum character. It is natural then to wonder about the effect of decoherence. Here, we develop the theory of current ...
Adiabatic deprotonation as an important competing pathway to ESIPT in photoacidic 2-phenylphenols
(Royal Society of Chemistry, 2019-05)
ESIPT (Excited State Intramolecular Proton Transfer) to C atom in 2-phenylphenol is known to be an intrinsically inefficient process. However, to the best of our knowledge, a structure-ESIPT efficiency relationship has not ...
Securing coherence rephasing with a pair of adiabatic rapid passages
(IOP Publishing, 2013-05)
Coherence rephasing is an essential step in quantum storage protocols that use echo-based strategies. We present a thorough analysis on how two adiabatic rapid passages (ARPs) are able to rephase atomic coherences in an ...
Work done on a single-particle gas during an adiabatic compression and expansion process
We compute the average work done by an external agent, driving a piston at constant speed, over a single-particle gas going through an adiabatic compression and expansion process. To do so, we get the analytical expression ...
