Study of the transition from conduction to injection in an electrohydrodynamic flow in blade-plane geometry
(Elsevier, 2017)
A dielectric fluid can be set into motion with the help of electric forces, mainly Coulomb force. This phenomenon, called electroconvection, can be induced by electrohydrodynamic conduction, injection, and induction. ...

Decoherence and quantum quench: Their relationship with excited state quantum phase transitions
(American Institute of Physics, 2012)
We study the similarities and differences between the phenomena of Quantum Decoherence and Quantum Quench in presence of an Excited State Quantum Phase Transition (ESQPT). We analyze, on one hand, the decoherence induced ...

I+D para detectar isótopos de difícil medida
(Empresa Nacional de Residuos Radioactivos, ENRESA, 2012)
Desde que el Centro Nacional de Aceleradores (CNA) abriera sus puertas en 1997, los investigadores españoles cuentan con un laboratorio de referencia para estudiar la caracterización y modificación de materiales. Uno de los ...

Charge injection enhanced natural convection heat transfer in horizontal concentric annuli filled with a dielectric liquid
(Elsevier, 2016)
The natural convection heat transfer in a highly insulating liquid contained between two horizontal concentric cylinders is shown by two-dimensional numerical simulations to be noticeably enhanced by imposing a direct ...

On two-dimensional finite amplitude electro-convection in a dielectric liquid induced by a strong unipolar injection
(Elsevier, 2015)
The hydrodynamic stability of a dielectric liquid subjected to strong unipolar injection is numerically investigated. We determined the linear criterion Tc (T being the electric Rayleigh number) and finite amplitude one ...

Quantitative study of coherent pairing modes with two-neutron transfer: Sn isotopes
(American Physical Society, 2013)
Pairing rotations and pairing vibrations are collective modes associated with a field, the pair field, which changes the number of particles by two. Consequently, they can be studied at profit with the help of two-particle ...

Phase diagram of the two-fluid Lipkin model: A "butterfly" catastrophe
(American Physical Society, 2016-03-31)
Background: In the past few decades quantum phase transitions have been of great interest in nuclear physics. In this context, two-fluid algebraic models are ideal systems to study how the concept of quantum phase transition ...

Understanding Einstein’s Viewpoint on Quantum Mechanics
(ABHPS, 2015)
The controversy between Einstein and Bohr about quantum mechanics is a classic. On the one hand, Einstein rejected it because of its unpredictable essence, while Bohr had no trouble accepting the limits imposed by Nature ...

Imaging biomarkers for steatohepatitis and fibrosis detection in non-alcoholic fatty liver disease
(Nature Publishing Group, 2016-08)
There is a need, in NAFLD management, to develop non-invasive methods to detect steatohepatitis (NASH) and to predict advanced fibrosis stages. We evaluated a tool based on optical analysis of liver magnetic resonance ...

The breakup length of harmonically stimulated capillary jets
(American Institute of Physics, 2014)
A simple transfer function that can predict the breakup length of a pressure-modulated capillary jet is rigorously deduced from first principles. In this paper, the initial velocity modulation of a stimulated jet is given ...
