Multi-Band Petahertz Currents Resolved via High Harmonic Generation Spectroscopy
Ayelet Julie Uzan, Gal Orenstein, Álvaro Jiménez-Galán +13
Strong field driven electric currents in condensed matter systems open new frontiers in petahertz electronics. In this regime new challenges arise as the role of the band structure…
Amplification of intense light fields by nearly free electrons
Mary Matthews, Felipe Morales, Alexander Patas +10
Light can be used to modify and control properties of media, as in the case of electromagnetically induced transparency or, more recently, for the generation of slow light or brigh…
Locally and globally chiral fields for ultimate control of chiral light matter interaction
David Ayuso, Ofer Neufeld, Andres F. Ordonez +5
Light is one of the most powerful and precise tools allowing us to control, shape and create new phases of matter. In this task, the magnetic component of a light wave has so far p…
Topological strong field physics on sub-laser cycle time scale
R. E. F. Silva, Á. Jiménez-Galán, B. Amorim +2
Sub-laser cycle time scale of electronic response to strong laser fields enables attosecond dynamical imaging in atoms, molecules and solids. Optical tunneling and high harmonic ge…
Control of attosecond light polarization in two-color bi-circular fields
Álvaro Jiménez-Galán, Nick Zhavoronkov, David Ayuso +6
We develop theoretically and confirm both numerically and experimentally a comprehensive analytical model which describes the propensity rules in the emission of circularly polariz…
Strong-field control and enhancement of chiral response in bi-elliptical high-order harmonic generation: an analytical model
David Ayuso, Piero Decleva, Serguei Patchkovskii +1
The generation of high-order harmonics in a medium of chiral molecules driven by intense bi-elliptical laser fields can lead to strong chiroptical response in a broad range of harm…
Electron correlations and pre-collision in the re-collision picture of high harmonic generation
Zdeněk Mašín, Alex G. Harvey, Michael Spanner +3
We discuss the seminal three-step model and the recollision picture in the context of high harmonic generation in molecules. In particular, we stress the importance of multi-electr…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
