Curvature-induced bound states in quantum wires
Tim Bergmann, Benjamin Schwager, Jamal Berakdar
A classical particle under spatial constraints is strictly confined to live on a specific space manifold or path, but this assumption is incompatible with the zero-point fluctuatio…

Laser-Dressed States on Riemannian Manifolds: A Generalization of the Kramers-Henneberger Transformation
Hannah Bendin, Benjamin Schwager, Jamal Berakdar
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 qua…

Wigner time delay and Hartman effect in quantum motion along deformed Riemannian manifolds
Benjamin Schwager, Lars Meschede, Jamal Berakdar
Elastic scattering of a wave can be quantified by a shift in the phase with respect to the incoming wave phase. A qualitative measure of the time during which the effect occurs is…
