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…
Attosecond physics in optical near fields
Jonas Heimerl, Stefan Meier, Anne Herzig +8
Attosecond science, the electron control by the field of ultrashort laser pulses, is maturing into lightfield-driven electronics, called petahertz electronics. Based on optical fie…
Soft X-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 m ultrafast laser
Drew Morrill, Will Hettel, Daniel Carlson +15
High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft X-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumpe…
Optical control of electrons in a Floquet topological insulator
Daniel M. B. Lesko, Tobias Weitz, Simon Wittigschlager +4
Light-dressed materials hold enormous potential for generating new electronic properties. The band structure resulting from light-dressing can exhibit starkly different quantum and…
