Probing topological Floquet states in WSe2 using circular dichroism in time- and angle-resolved photoemission spectroscopy
Observing signatures of light-induced topological Floquet states in materials has been
shown to be very challenging. Angle-resolved photoemission spectroscopy (ARPES) is well …

Band nonlinearity-enabled manipulation of Dirac nodes, Weyl cones, and valleytronics with intense linearly polarized light
We study low-frequency linearly polarized laser-dressing in materials with valley (graphene
and hexagonal-Boron-Nitride) and topological (Dirac-and Weyl-semimetals) properties. In …
