F2 region maximum electron density height predictions for South American latitudes
(American Geophysical Union, 2003-12)
Values of the F2 region maximum electron density height (hmF2) calculated using ground ionosonde data at South American latitudes are used to check the validity of the International Reference Ionosphere (IRI) to predict ...
Real-time quantum dynamics of long-range electronic excitation transfer in plasmonic nanoantennas
(American Chemical Society, 2017-08-05)
Using large-scale, real-time, quantum dynamics calculations, we present a detailed analysis of electronic excitation transfer (EET) mechanisms in a multiparticle plasmonic nanoantenna system. Specifically, we utilize ...
Insights from the zero-angular-momentum wave in single and double ionization of He by fast electrons
(American Physical Society, 2014-01)
In a recent contribution our group proposed a perturbative approach to deal with the open problem of double ionization of helium by electron impact. The goal of this work is to delve into the physics of the scattering ...
Nonadiabatic features of electron pumping through a quantum dot in the Kondo regime
(American Physical Society, 2008-12)
We investigate the behavior of the dc electronic current Jdc in an interacting quantum dot driven by two ac local potentials oscillating with a frequency Ω0 and a phase lag φ. We provide analytical functions to describe ...
Electronic coherences and vibrational wave-packets in single molecules studied with femtosecond phase-controlled spectroscopy
(Royal Society of Chemistry, 2011-01)
Employing femtosecond pulse-shaping techniques we investigate ultrafast, coherent and incoherent dynamics in single molecules at room temperature. In first experiments single molecules are excited into their purely electronic ...
High magnetic field detunes vibronic resonances in photosynthetic light harvesting
(American Chemical Society, 2018-09)
The origin and role of oscillatory features detected in recent femtosecond spectroscopy experiments of photosynthetic complexes remain elusive. A key hypothesis underneath of these observations relies on electronic-vibrational ...
Artes electrónicas argentinas en el zaguán de la escena internacional: Idearios de modernización y devenires institucionales oscilantesArgentinean electronic arts in the hallway of the international scene: Modernisation imaginaries and oscillating institutional developments
(Universitat Oberta de Catalunya, 2017-06)
Los cruces entre el arte, la ciencia y la tecnología se extienden en una escena vasta y relativamente indefinida, modulada por una serie de cualidades inherentes a sus prácticas en permanente tensión: a las revisitadas ...
Motion-induced radiation due to an atom in the presence of a graphene plane
(MDPI AG, 2021-05)
We study the motion-induced radiation due to the non-relativistic motion of an atom, coupled to the vacuum electromagnetic field by an electric dipole term, in the presence of a static graphene plate. After computing the ...
An: Ab initio multiple cloning approach for the simulation of photoinduced dynamics in conjugated molecules
(Royal Society of Chemistry, 2018-05)
We present a new implementation of the Ab Initio Multiple Cloning (AIMC) method, which is applied for non-adiabatic excited-state molecular dynamics simulations of photoinduced processes in conjugated molecules. Within our ...
Non-adiabatic excited state molecular dynamics of phenylene ethynylene dendrimer using a multiconfigurational Ehrenfest approach
(Royal Society of Chemistry, 2016-04)
Photoinduced dynamics of electronic and vibrational unidirectional energy transfer between meta-linked building blocks in a phenylene ethynylene dendrimer is simulated using a multiconfigurational Ehrenfest in time-dependent ...
