Induced current in quantum and classical ratchets
(World Scientific, 2010-02)
In a previous work, we described transport in a classical, externally driven, overdamped ratchet. A transport current arises under two possible conditions: either by increasing the external driving or by adding an optimal ...
Active colloidal chains with cilia- and flagella-like motion
(IOP Publishing Ltd, 2018-05-04)
It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of ...
Effects of Inertia on the Steady-Shear Rheology of Disordered Solids
(American Physical Society, 2016-02)
We study the finite-shear-rate rheology of disordered solids by means of molecular dynamics simulations in two dimensions. By systematically varying the damping strength ζ in the low-temperature limit, we identify two ...
Transport in a chain of asymmetric cavities: Effects of the concentration with hard-core interaction
(American Physical Society, 2013-11)
We studied the transport process of overdamped Brownian particles, in a chain of asymmetric cavities, interacting through a hard-core potential. When a force is applied in opposite directions a difference in the drift ...
Anomalous Slowdown of Polymer Detachment Dynamics on Carbon Nanotubes
(American Physical Society, 2019-05)
The "wrapping" of polymer chains on the surface of carbon nanotubes allows one to obtain multifunctional hybrid materials with unique properties for a wide range of applications in biomedicine, electronics, nanocomposites, ...
Inertia and universality of avalanche statistics: The case of slowly deformed amorphous solids
(American Physical Society, 2017-01-12)
By means of a finite elements technique we solve numerically the dynamics of an amorphous solid under deformation in the quasistatic driving limit. We study the noise statistics of the stress-strain signal in the steady-state ...
Curl forces and the nonlinear Fokker-Planck equation
(American Physical Society, 2016-12)
Nonlinear Fokker-Planck equations endowed with curl drift forces are investigated. The conditions under which these evolution equations admit stationary solutions, which are q exponentials of an appropriate potential ...
Population inversion and dynamical phase transitions in a driven superconductor
(American Physical Society, 2018-12)
We consider a superconductor in which the density of states at the Fermi level or the pairing interaction is driven periodically with a frequency larger than the superconducting gap in the collisionless regime. We show by ...
Understanding the Lévy Ratchets in Terms of Lévy Jumps
(Iop Publishing, 2013-02)
We investigate the overdamped dynamics of a particle in a spatially periodic potential with broken reflection symmetry and subject to the action of a symmetric white Lévy noise. The system (referred to as the Lévy ratchet) ...
Modeling upper eyelid kinematics during spontaneous and reflex blinks
(Elsevier B.V., 2010-08-15)
To test a mathematical model for measuring blinking kinematics.Spontaneous and reflex blinks of 23 healthy subjects were recorded with two different temporal resolutions. A magnetic search coil was used to record 77 blinks ...
