Dynamical mean field theory with the density matrix renormalization group
(American Physical Society, 2004-12)
A new algorithm to solve the dynamical mean field theory (DMFT) equations of strongly correlated models exploiting the DMRG methodology was presented. The methods uses the density matrix renormalization group technique to ...
Vacuum effects on the properties of nuclear matter under an external magnetic field
(American Physical Society, 2019-12-09)
The effects of the Dirac sea of nucleons are investigated within a covariant model of the hadronic interaction. I extend the usual mean field approximation and present a procedure to deal with divergences which are ...
Algebraic Structures, Physics and Geometry from a Unified Field Theoretical Framework
(Springer, 2015-10)
Starting from a Unified Field Theory (UFT) proposed previously by the author, the possible fermionic representations arising from the same spacetime are considered from the algebraic and geometrical viewpoint. We specifically ...
Raman investigation of electric field induced molecular modifications in organic field effect transistors
(Politécnico Grancolombiano, 2013)
Determination of the Local Electric Field at Au/SAM Interfaces Using the Vibrational Stark Effect
(American Chemical Society, 2017-10)
A comprehensive understanding of physical and chemical processes at biological membranes requires the knowledge of the interfacial electric field which is a key parameter for controlling molecular structures and reaction ...
Equivalence principle in chameleon models
(American Physical Society, 2018-05)
Most theories that predict time and/or space variation of fundamental constants also predict violations of the weak equivalence principle (WEP). In 2004 Khoury and Weltman [1] proposed the so called chameleon field arguing ...
An architectural analysis of the elongation of field-grown sunflower root systems. Elements for modelling the effects of temperature and intercepted radiation
(Society for Experimental Biology, 1996-03)
The effects of photosynthetic photon flux density (PPFD) and soil temperature on root system elongation rate have been analysed by using an architectural framework. Root elongation rate was analysed by considering three ...
Subsurface architecture of Las Bombas volcano circular structure (Southern Mendoza, Argentina) from geophysical studies
(Pergamon-Elsevier Science Ltd, 2017-08)
The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large ...
Approximate average head models for EEG source imaging
(Elsevier Science, 2009-12-15)
We examine the performance of approximate models (AM) of the head in solving the EEG inverse problem. The AM are needed when the individual’s MRI is not available. We simulate the electric potential distribution generated ...
Fréedericksz transition on a phenomenological model for a nematic inhomogeneous superfluid in presence of an electric field
(Elsevier Science, 2020-12)
In this article we derive a Ginzburg–Landau energy functional for a nematic inhomogeneous superfluid in presence of an electric field. The molecules occupy an infinite cylinder Ω with cross section D. We suppose vacuum in ...
