Probing temperature dependent non-radiative decay channels in CrSBr with nonlinear optics
Minjiang Dan, Till Weickhardt, Paul Herrmann +9
Among the recently discovered layered magnetic materials, the antiferromagnet CrSBr has attracted considerable interest thanks to its stability, quasi-one-dimensional crystal struc…
Nonlinear Circular Dichroism Reveals the Local Berry Curvature
Nele Tornow, Paul Herrmann, Clemens Schneider +3
Light-matter interactions are governed by conservation laws of energy and momentum. For harmonic generation in crystalline solids, energy conservation imposes that incoming pho…
Roadmap for Photonics with 2D Materials
F. Javier García de Abajo, D. N. Basov, Frank H. L. Koppens +145
Triggered by the development of exfoliation and the identification of a wide range of extraordinary physical properties in self-standing films consisting of one or few atomic layer…
Direct measurement of broken time-reversal symmetry in centrosymmetric and non-centrosymmetric atomically thin crystals with nonlinear Kerr rotation
Florentine Friedrich, Paul Herrmann, Shridhar Sanjay Shanbhag +3
Time-reversal symmetry, together with space-inversion symmetry, is one of the defining properties of crystals, underlying phenomena such as magnetism, topology and non-trivial spin…
Valley Polarization-Electric Dipole Interference and Nonlinear Chiral Selection Rules in Monolayer WSe
Paul Herrmann, Sebastian Klimmer, Till Weickhardt +6
In monolayer transition metal dichalcogenides time-reversal symmetry, combined with space-inversion symmetry, defines the spin-valley degree of freedom. As such, engineering and co…
