Inducing critical phenomena in spin chains through sparse alternating fields
(American Physical Society, 2019-01-09)
We analyze the phase diagram of the exact ground state (GS) of spin-s chains with ferromagnetic XXZ couplings under n-alternating field configurations, i.e., sparse alternating fields having nodes at n − 1 contiguous sites. ...
Fluxo de coerência quântica para um qubit evoluindo sobre a ação de canais quânticos
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2016-08-23)
Quantum Coherence (QC) has a fundamental role in Quantum Mechanics (QM). It has
been studied since the emergence of QM. However, this quantum feature is easily destroyed
when a physical system interacts with the environment. ...
Controlled high-fidelity navigation in the charge stability diagram of a double quantum dot
(Iop Publishing, 2015-03)
We propose an efficient control protocol for charge transfer in a double quantum dot. We consider numerically a two-dimensional model system, where the quantum dots are subjected to time-dependent electric fields ...
Correlações quânticas e transição quântico-clássica em cavidades ópticas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2014-02-27)
This thesis consists of three studies in the context of cavity quantum electrodynam- ics. Firstly, we investigate the quantum-to-classical transition of a dissipative cavity .eld by measuring the correlations between two ...
Dynamical memory effects in correlated quantum channels
(Amer Physical Soc, 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 ...

Dynamical dimerization phase in Jaynes-Cummings lattices
(IOP Publishing, 2020)
We report on an emergent dynamical phase of a strongly-correlated light-matter system, which is governed by dimerization processes due to short-range and long-range two-body interactions. The dynamical phase is characterized ...
Quantum mutual information, fragile systems and emergence
(MDPI, 2022-11)
In this paper, we present an analytical description of emergence from the density matrix framework as a state of knowledge of the system, and its generalized probability formulation. This description is based on the idea ...
Correction to: Quantum Systems Simulatability Through Classical Networks (International Journal of Theoretical Physics, (2022), 61, 2, (30), 10.1007/s10773-022-05045-6)
