Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
Comparison of wave-mixing processes in rarefied gas and QED vacuum using numerical simulations
Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +3
We study the conditions required to distinguish laser-induced nonlinear quantum electrodynamics (QED) effects in vacuum from competing signals due to interactions of laser pulses w…
Generation of directed electron beams by tight focusing of an ultrashort IR laser in a near-critical plasma
Marianna Lytova, François Fillion-Gourdeau, Simon Vallières +4
Recent studies have demonstrated the possibility of accelerating electrons to MeV energies in ambient air using tightly focused laser configurations. In this article, we explore po…
Efficient ion re-acceleration in laboratory-produced interpenetrating collisionless shocks
W. Yao, I. Cohen, P. Suarez Gerona +20
Although the origin of cosmic rays (CRs) remains an open question, collisionless magnetized shock waves are widely regarded as key sites for particle acceleration. Recent theories…
Electron-phonon-dominated charge-density-wave fluctuations in TiSe accessed by ultrafast nonequilibrium dynamics
Sotirios Fragkos, Hibiki Orio, Nina Girotto Erhardt +17
The complex phase diagram of 1T-TiSe2 consists of a charge density wave (CDW) below 200 K, and CDW fluctuations of still unknown origin at higher temperatures. Here, we use time-re…
Time- and Polarization-Resolved Extreme Ultraviolet Momentum Microscopy
Sotirios Fragkos, Quentin Courtade, Olena Tkach +7
We report the development of an instrument combining an ultrafast, high-repetition-rate, polarization-tunable monochromatic extreme ultraviolet (XUV, 21.6 eV) beamline and a next-g…
