Laser-dressed states on Riemannian manifolds: A generalization of the Kramers-Henneberger transformation

open access: yesPhysical Review Research
Quantum particles under geometric constraints are sensitive to the geometry and topology of the underlying space. We analytically study the laser-driven nonlinear dynamics of a quantum particle whose motion is constrained to a two-dimensional Riemannian ...

Excitonic topology and quantum geometry in organic semiconductors

open access: yesNature Communications
Excitons drive the optoelectronic properties of organic semiconductors which underpin devices including solar cells and light-emitting diodes. Here we show that excitons can exhibit topologically non-trivial states protected by inversion symmetry and ...
