Distribution of absorbed photons in the tunneling ionization process

open access: yesScientific Reports, 2021
We describe a procedure that allows us to solve the three-dimensional time-dependent Schrödinger equation for an atom interacting with a quantized one-mode electromagnetic field. Atom-field interaction is treated in an ab initio way prescribed by quantum

A New Class of Retrocausal Models

open access: yesEntropy, 2018
Globally-constrained classical fields provide a unexplored framework for modeling quantum phenomena, including apparent particle-like behavior. By allowing controllable constraints on unknown past fields, these models are retrocausal but not retro ...

Quantum framework for describing retarded and nonretarded molecular interactions in external electric fields

open access: yesPhysical Review Research, 2022
We employ various quantum-mechanical approaches for studying the impact of electric fields on both nonretarded and retarded noncovalent interactions between atoms or molecules.

A posteriori error estimation for stochastic static problems [PDF]

open access: yes, 2014
To solve stochastic static field problems, a discretization by the Finite Element Method can be used. A system of equations is obtained with the unknowns (scalar potential at nodes for example) being random variables. To solve this stochastic system, the

Macroscopic test of quantum mechanics versus stochastic electrodynamics [PDF]

open access: yes, 1997
We identify a test of quantum mechanics versus macroscopic local realism in the form of stochastic electrodynamics.

Assessment of weak-coupling approximations on a driven two-level system under dissipation

open access: yesNew Journal of Physics, 2021
The standard weak-coupling approximations associated to open quantum systems have been extensively used in the description of a two-level quantum system, qubit, subjected to relatively weak dissipation compared with the qubit frequency.

Research-based course materials and assessments for upper-division electrodynamics (E&M II) [PDF]

open access: yes, 2013
Favorable outcomes from ongoing research at the University of Colorado Boulder on student learning in junior-level electrostatics (E&M I) have led us to extend this work to upper-division electrodynamics (E&M II).

Optomechanical sideband asymmetry explained by stochastic electrodynamics

open access: yes, 2022
Within the framework of stochastic electrodynamics we derive the noise spectrum of a laser beam reflected from a suspended mirror. The electromagnetic field follows Maxwell's equations and is described by a deterministic part that accounts for the laser ...

Effects of energetic electrons on the electrodynamics in the ionosphere [PDF]

open access: yes, 2004
International audienceFrom the observations by the PIXIE and UVI cameras on board the Polar satellite, we derive global maps of the precipitating electron energy spectra from less than 1keV to 100keV.
