Polarization-Shaped Strong Field Control over Valley Polarization with Mid-IR Light
Igor Tyulnev, Julita Poborska, Álvaro Jiménez-Galán +4
We induce control over valley polarization with a polarization-shaped mid-infrared light field. The polarization state of the trefoil-shaped pump fields is measured by high harmoni…
Sub-cycle valleytronics: control of valley polarization using few-cycle linearly polarized pulses
Álvaro Jiménez-Galán, Rui Silva, Olga Smirnova +1
So far, selective excitation of a desired valley in the Brillouin zone of a hexagonal two-dimensional material has relied on using circularly polarized fields. We theoretically dem…
Lightwave topology for strong-field valleytronics
Á. Jiménez-Galán, R. E. F. Silva, O. Smirnova +1
Modern light generation technology offers extraordinary capabilities for sculpting light pulses, with full control over individual electric field oscillations within each laser cyc…
Origin of strong-field induced low-order harmonic generation in amorphous solids
P. Jürgens, B. Liewehr, B. Kruse +8
Kerr-type nonlinearities form the basis for our physical understanding of nonlinear optical phenomena in condensed matter, such as self-focusing, solitary waves, and wave mixing. I…
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…
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…
