Attosecond time-resolved imaging of molecular structure by photoelectron holography.
Xue-Bin Bian,André D. Bandrauk +1 more
TL;DR: It is shown that both short and long rescattered electron trajectories can be imaged from the momentum distribution, suggesting an attosecond time-resolved way of imaging molecular structure obtained from laser induced rescattering of ionized electrons.

Heide Ibrahim,Benji Wales,Samuel Beaulieu,Bruno E. Schmidt,Nicolas Thiré,Emmanuel Penka Fowe,Éric Bisson,Christoph T. Hebeisen,Vincent Wanie,Mathieu Giguère,Jean-Claude Kieffer,Michael Spanner,André D. Bandrauk,Joseph Sanderson,Michael S. Schuurman,François Légaré +15 more
TL;DR: Two basic chemical reactions simultaneously are investigated simultaneously: proton migration and C=C bond breaking, triggered by multiphoton ionization, in excellent agreement with the timescales and relaxation pathways predicted by new and quantitative ab initio trajectory simulations.
Numerical Solution of the Time-Dependent Dirac Equation in Coordinate Space without Fermion-Doubling
François Fillion-Gourdeau,François Fillion-Gourdeau,François Fillion-Gourdeau,Emmanuel Lorin,Emmanuel Lorin,André D. Bandrauk,André D. Bandrauk +6 more
TL;DR: It is shown that this numerical method for the solution of the time-dependent Dirac equation is free from spurious solutions related to the fermion-doubling problem and that it can be parallelized very efficiently.

Photon Momentum Sharing between an Electron and an Ion in Photoionization: From One-Photon (Photoelectric Effect) to Multiphoton Absorption
TL;DR: There is very different partitioning of the photon momentum in one-photon ionization (the photoelectric effect) as compared to multiphoton processes, suggesting that there is a rich, unexplored physics to be studied between these two limits which can be generated with current ultrafast laser technology.

Laser Coulomb-explosion imaging of small molecules
François Légaré,François Légaré,Kevin F. Lee,Kevin F. Lee,Igor Litvinyuk,P. W. Dooley,P. W. Dooley,S. S. Wesolowski,Philip R. Bunker,Péter Dombi,Ferenc Krausz,André D. Bandrauk,David M. Villeneuve,Paul B. Corkum +13 more
TL;DR: In this paper, Coulomb's law or ab initio potentials were used to reconstruct the molecular structure of a few-cycle laser pulses to ionize molecules to the point of Coulomb explosion.
