Work exchange, geometric magnetization, and fluctuation-dissipation relations in a quantum dot under adiabatic magnetoelectric driving
(American Physical Society, 2019-03)
We study the adiabatic dynamics of the charge, spin, and energy of a quantum dot with a Coulomb interaction under two-parameter driving, associated to time-dependent gate voltage and magnetic field. The quantum dot is ...
Dissociação de partículas num potencial rugoso sob a ação de perturbação dependente do tempo
(Universidade Estadual Paulista (Unesp), 2017-07-18)
O objetivo deste trabalho é estudar a dinâmica e o controle da fotodissociação de uma molécula diatômica submetida a um potencial rugoso, o qual é aplicado em diversas áreas da ciência para modelar processos naturais, ...
Equation of Motion Governing the Dynamics of Vertically Collapsing Buildings
(ASCE-AMER SOC CIVIL ENGINEERSRESTON, 2012-12)
The present paper aims at contributing to a discussion, opened by several authors, on the proper equation of motion that governs the vertical collapse of buildings. The most striking and tragic example is that of the World ...
Non-uniform drag force on the Fermi accelerator model

Flaming 2 Pi Kinks In Parametrically Driven Systems
(2016)
Macroscopic extended systems with dissipation and injection of energy can exhibit particlelike solutions. Dissipative kinks with an oscillatory cloak and a family of localized states that connect uniform symmetric states ...
Quantum vacuum fluctuations in presence of dissipative bodies: Dynamical approach for nonequilibrium and squeezed states
(American Physical Society, 2017-01)
The present work contributes to the study of nonequilibrium aspects of the Casimir forces with the introduction of squeezed states in the calculations. Throughout this article two main results can be found, being both ...
Multiphysics behavior of a magneto-rheological damper and experimental validation
(2014)
This investigation deals with the design, manufacturing, and testing of a large-capacity MR damper prototype. The MR damper uses external coils that magnetize the MR-fluid as it moves out of the main cylinder through an ...
A simplified Fermi Accelerator Model under quadratic frictional force
(Sociedade Brasileira de Física, 2013)
Ambiguities on the hamiltonian formulation of the free falling particle with quadratic dissipation
(2011)
For a free falling particle moving in a media which has quadratic velocity force effect on the particle, two equivalent constants of motion, with units of energy, two Lagrangians, and two Hamiltonians are deduced. These ...
