In-plane optically tunable magnetic states in 2D materials via tailored femtosecond laser driving
Shuang Liu, Oren Cohen, Peng Chen +1
It is well established that light can control magnetism in matter, e.g. via the inverse Faraday effect or ultrafast demagnetization. However, such control is typically limited to m…
Photoelectron chiral dichroism induced by lasers without helicity via chiral hole wave-packets
Gal Bouskila, Avner Fleischer, Ofer Neufeld
Photoelectron circular dichroism (PECD) is a method where randomly oriented chiral molecules are photoionized due to irradiation by circularly-polarized lasers, yielding large chir…
Second-quantized numerical simulations of tunable entanglement in quantum high harmonic generation
Sebastián de-la-Peña, Heiko Appel, Angel Rubio +1
Quantum high-harmonic generation (HHG) is a prominent and growing field of research with potential capabilities of providing high photon-number entangled states of light. However,…
Attosecond-resolved probing of recolliding electron wave packets in liquids and aqueous solutions
Angana Mondal, Nicolas Tancogne-Dejean, George Trenins +8
High-harmonic spectroscopy (HHS) in liquids promises real-time access to ultrafast electronic dynamics in the native environment of chemical and biological processes. While electro…
Laser Driven Bulk-to-Layered Phase Transition
Shuang Liu, Oren Cohen, Ofer Neufeld +1
Laser-induced phase transitions offer pathways of phase transitions that are inaccessible by conventional stimuli. In this study, we conduct ab initio simulations to numerically de…
Probing broken time-reversal symmetry with tailored-light photocurrents
Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4
Light-field-driven photocurrents represent a powerful tool for generating photocurrents without external bias in light-matter systems that lack inversion symmetry. While these phot…
Linearly-polarized few-cycle pulses drive carrier envelope phase-sensitive coherent magnetization injection
Ofer Neufeld
Circularly-polarized light is well-known to induce, or flip the direction of, magnetization in solids. At its heart, this arises from time-reversal symmetry breaking by the vector…
Correlation-induced phase shifts and time delays in resonance enhanced high harmonic generation from Cr+
Yoad Aharon, Adi Pick, Amir Hen +2
We investigate resonance-enhanced high harmonic generation (rHHG) in Cr+ by comparing a 1D shape-resonant model, time-dependent density functional theory (TDDFT), and independent p…
Multi-plateau high-harmonic generation in liquids driven by off-site recombination
Angana Mondal, Ofer Neufeld, Tadas Balciunas +7
Non-perturbative high-harmonic generation (HHG) has recently been observed in the liquid phase, where it was demonstrated to have a different physical mechanism compared to gas and…
Symmetries and selection rules in photoelectron chiral dichroism from tailored light
Ofer Neufeld
Photoelectron circular dichroism (PECD) is a method whereby randomly oriented chiral molecules are irradiated by circularly-polarized light, photoionizing electrons, which are meas…
Two-color harmonic spectroscopy of ultrafast Dirac electron dynamics
Zhaopin Chen, Camilo Granados, Eyal Uzner +5
High-harmonic generation (HHG), the hallmark effect of attosecond science, is a nonperturbative nonlinear process leading to the emission of high-harmonic light from gases and soli…
