Forward and hybrid path-integral methods in photoelectron holography: sub-barrier corrections, initial sampling and momentum mapping
L. Cruz Rodriguez, T. Rook, B. B. Augstein +2
We construct two strong-field path integral methods with full Coulomb distortion, in which the quantum pathways are mimicked by interfering electron orbits: the rate-based CQSFA (R…
Experimental observation of effective gravity and two times physics in ferrofluid-based hyperbolic metamaterials
V. N. Smolyaninova, J. Cartelli, B. Augstein +3
Recently it was proposed that extraordinary light waves in hyperbolic metamaterials exhibit two times physics behavior (Phys. Rev. Lett. 105, 067402, 2010). We report experimental…
Extracting an electron's angle of return from shifted interference patterns in macroscopic high-harmonic spectra of diatomic molecules
T. Das, B. B. Augstein, C. Figueira de Morisson Faria +3
We investigate high-order harmonic spectra from aligned diatomic molecules in intense driving fields whose components have orthogonal polarizations. We focus on how the driving-fie…
High-order harmonic generation from diatomic molecules in elliptically polarized driving fields: a generalized interference condition
T. Das, B. B. Augstein, C. Figueira de Morisson Faria
We investigate the influence of intense, elliptically polarized driving fields on high-order harmonic spectra from aligned diatomic molecules. We derive a generalized two-center in…
Bohmian trajectory analysis of high-order harmonic generation: ensemble averages, non-locality and quantitative aspects
J. Wu, B. B. Augstein, C. Figueira de Morisson Faria
We perform a Bohmian-trajectory analysis of high-order harmonic generation (HHG), focusing on the fact that typical HHG spectra are best reproduced by the Bohmian trajectory starti…
Local dynamics in high-order harmonic generation using Bohmian trajectories
J. Wu, B. B. Augstein, C. Figueira de Morisson Faria
We investigate high-order harmonic generation from a Bohmian-mechanical perspective, and find that the innermost part of the core, represented by a single Bohmian trajectory, leads…
Excitation, two-center interference and the orbital geometry in laser-induced nonsequential double ionization of diatomic molecules
T. Shaaran, B. B. Augstein, C. Figueira de Morisson Faria
We address the influence of the molecular orbital geometry and of the molecular alignment with respect to the laser-field polarization on laser-induced nonsequential double ionizat…
Influence of asymmetry and nodal planes on high-harmonic generation in heteronuclear molecules
B. B. Augstein, C. Figueira de Morisson Faria
The relation between high-harmonic spectra and the geometry of the molecular orbitals in position and momentum space is investigated. In particular we choose two isoelectronic pair…
Influence of energetically close orbitals on molecular high-order harmonic generation
C. Figueira de Morisson Faria, B. B. Augstein
We investigate the contributions from the and and molecular orbitals in high-order harmonic generation in , with particular emphasis on quantum-interferenc…
