High temperature far-infrared dynamics of orthorhombic NdMnO3: emissivity and reflectivity
(IOP Publishing, 2013-05-16)
We report on near normal far- and mid-infrared emission and reflectivity of NdMnO3 perovskite from room temperature to sample decomposition above 1800 K. At 300 K the number of infrared active phonons is in close agreement ...
Spatio-temporal correlations in models of collective motion ruled by different dynamical laws
(IOP Publishing, 2016-11)
Information transfer is an essential factor in determining the robustness of biological systems with distributed control. The most direct way to study the mechanisms ruling information transfer is to experimentally observe ...
Two-Dimensional Non-Fermi-Liquid Metals: A Solvable Large-N Limit
(American Physical Society, 2019-08-29)
Significant effort has been devoted to the study of “non-Fermi-liquid” (NFL) metals: gapless conducting systems that lack a quasiparticle description. One class of NFL metals involves a finite density of fermions interacting ...
Environmentally induced quantum dynamical phase transition in the spin swapping operation
(American Institute of Physics, 2006-12)
Quantum information processing relies on coherent quantum dynamics for a precise control of its basic operations. A swapping gate in a two-spin system exchanges the degenerate states ∫↑, ↓〉 and ∫↓, ↑〉. In NMR, this is ...
Nonlinear fokker-planck equation approach to systems of interacting particles: Thermostatistical features related to the range of the interactions
(Multidisciplinary Digital Publishing Institute, 2020-02)
Nonlinear Fokker-Planck equations (NLFPEs) constitute useful effective descriptions of some interacting many-body systems. Important instances of these nonlinear evolution equations are closely related to the thermostatistics ...
From the nonlinear Fokker-Planck equation to the Vlasov description and back: Confined interacting particles with drag
(American Physical Society, 2018-02)
Nonlinear Fokker-Planck equations endowed with power-law diffusion terms have proven to be valuable tools for the study of diverse complex systems in physics, biology, and other fields. The nonlinearity appearing in these ...
Charged Brownian particles: Kramers and Smoluchowski equations and the hydrothermodynamical picture
(2011-05-01)
We consider a charged Brownian gas under the influence of external and non-uniform electric, magnetic and mechanical fields, immersed in a non-uniform bath temperature. With the collision time as an expansion parameter, ...
Dynamic analysis and control PID path of a model type gantry crane
(2017-06-13)
This paper presents an alternate form for the dynamic modelling of a mechanical
system that simulates in real life a gantry crane type, using Euler’s classical mechanics and
Lagrange formalism, which allows find the ...
Modeling upper eyelid kinematics during spontaneous and reflex blinks
(2010)
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 us d to record 77 blinks ...
Evaluación sísmica de casas de mampostería de tierra vulnerables a modos de falla fuera del plano
(2017)
A common premise of the buildings seismic assessment is the occurrence of a global failure mode governed by in-plane failure mechanisms of walls. In the case of the traditional unconfined buildings of adobe or brick, this ...
