Dynamical memory effects in correlated quantum channels
(2016-09-23)
Memory effects play a fundamental role in the study of the dynamics of open quantum systems. There exist two conceptually distinct notions of memory discussed for quantum channels in the literature. In quantum information ...
Experimentally accessible measure to quantify the non-Markovian character of the dynamics of open quantum systems
(Grupo de Física Teórica y Matemática AplicadaMedellín, Colombia, 2022)
Teoria de controle ótimo em sistemas abertos
(Universidade Estadual Paulista (Unesp), 2018-01-29)
A teoria de informação e computação quântica é uma área de pesquisa que vem crescendo de maneira acentuada nos últimos anos devido aos inúmeros avanços tecnológicos que a acompanham. Neste mestrado começamos nossos estudos ...
Efficient finite-time measurements under thermal regimes
(SpringerHeidelberg, 2014-10)
Contrary to conventional quantum mechanics, which treats measurement as instantaneous, here we explore a model for finite-time measurement. The main two-level system interacts with the measurement apparatus in a Markovian ...
Dinâmica dissipativa em sistemas quânticos fortemente interagentes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-12-06)
In this thesis we investigate the dissipative dynamics in strongly interacting quantum
systems. The dissipative dynamics that we investigate has relevance in the generation
of non-classic states of light, such as the ...
Non-local effects at the onset of the chiral transition
(Sociedade Brasileira de Física, 2007-07-01)
Inspired by analytic results obtained for a systematic expansion of the memory kernel in dissipative quantum mechanics, we propose a phenomenological procedure to incorporate non-markovian corrections to the Langevin ...

Non-markovianity Through Accessible Information
(American Physical Society, 2014)
Influence of nonmagnetic impurity scattering on spin dynamics in diluted magnetic semiconductors
(American Physical Society, 2017-01)
The doping of semiconductors with magnetic impurities gives rise not only to a spin-spin interaction between quasifree carriers and magnetic impurities but also to a local spin-independent disorder potential for the carriers. ...
Quantum Trajectories in non-Markovian system via the reaction coordinate mapping
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-07-21)
Dynamics of systems coupled to an environment are usually hard to obtain; their solutions
rely on approximation, which may not be reliable in many cases. Here we use the Reaction
coordinate mapping and the Quantum ...
