Heat production and energy balance in nanoscale engines driven by time-dependent fields
(American Physical Society, 2007-12)
We present a formalism to study the heat transport and the power developed by the local driving fields on a quantum system coupled to macroscopic reservoirs. We show that, quite generally, two important mechanisms can take ...
Towards detecting traces of non-contact quantum friction in the corrections of the accumulated geometric phase
(Nature, 2020-02)
The geometric phase can be used as a fruitful venue of investigation to infer features of the quantum systems. Its application can reach new theoretical frontiers and imply innovative and challenging experimental proposals. ...
Nonlinear fluctuations in relativistic causal fluids
(Springer, 2020-07)
In the Second Order Theories (SOT) of real relativistic fluids, the non-ideal properties of the flows are described by a new set of dynamical tensor variables. In this work we explore the non-linear dynamics of those ...
Effect of lateral confinement on the apparent mass of granular dampers
(Springer, 2021-04)
We study, via discrete element method simulations, the apparent mass (m, the ratio of a driving force to a resulting acceleration) and loss factor (η, the ratio of dissipated to stored energy) of granular dampers attached ...
Atmospheric forcing as a source for ocean variability at the Brazil-Malvinas confluence zone
(Asociación Argentina de Geofísicos y Geodestas, 2001)
The goal of this study is to evaluate the impact of the atmospheric forcing of the scale of the storms on the oceanic circulation and temperature at the Brazil-Malvinas Confluence Zone. SST data and numerical simulations ...
Decrease of streamwise mean velocity of single spheres due to presence of a sparse network of immobile bed-mounted particles
(American Society of Civil Engineers, 2020)
The transport of spheres as a bed-load through a sparse network of immobile, bed-mounted submerged cylinders was experimentally studied to quantify how the mean velocity of the spheres in the streamwise direction is altered, ...
Dual constant-flux energy cascades to both large scales and small scales
(American Institute of Physics, 2017-11)
In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional fluids and wave turbulence ...
Gramicidin ion channels in a lipid bilayer supported on polyelectrolyte multilayer films: An electrochemical impedance study
(Royal Society of Chemistry, 2017-11)
Supported membranes on polymer cushions are of fundamental interest as models for cell membranes. The use of polyelectrolyte multilayers (PEMs) assembled by the layer by layer (LbL) technique as supports for a bilayer ...
Magnetization dynamics: path-integral formalism for the stochastic Landau–Lifshitz–Gilbert equation
(Iop Publishing, 2014-09)
We construct a path-integral representation of the generating functional for the dissipative dynamics of a classical magnetic moment as described by the stochastic generalization of the Landau–Lifshitz–Gilbert equation ...
Dust trapping around Lagrangian points in protoplanetary disks
(EDP Sciences, 2020-10)
Trojans are defined as objects that share the orbit of a planet at the stable Lagrangian points L4 and L5. In the Solar System, these bodies show a broad size distribution ranging from micrometer (μm) to centimeter (cm) ...
