Band nonlinearity-enabled manipulation of Dirac nodes, Weyl cones, and valleytronics with intense linearly polarized light
Ofer Neufeld, Hannes Hübener, Gregor Jotzu +2
We study low-frequency linearly-polarized laser-dressing in materials with valley (graphene and hexagonal-Boron-Nitride), and topological (Dirac- and Weyl-semimetals), properties.…
Are there universal signatures of topological phases in high harmonic generation? Probably not
Ofer Neufeld, Nicolas Tancogne-Dejean, Hannes Hübener +2
High harmonic generation (HHG) has developed in recent years as a promising tool for ultrafast materials spectroscopy. At the forefront of these advancements, several works propose…
Mapping light-dressed Floquet bands by highly nonlinear optical excitations and valley polarization
Anna Galler, Angel Rubio, Ofer Neufeld
Ultrafast nonlinear optical phenomena in solids have been attracting major interest as novel methodologies for femtosecond spectroscopy of electron dynamics and control of material…
