A duality of the classical action yields a reflection symmetry of the quantum energy spectrum
Michael Kreshchuk, Tobias Gulden
The concept of duality reflects a link between two seemingly different physical objects. An example in quantum mechanics is a situation where the spectra (or their parts) of two Ha…

Instanton calculus without equations of motion: semiclassics from monodromies of a Riemann surface
Tobias Gulden, Michael Janas, Alex Kamenev
Instanton calculations in semiclassical quantum mechanics rely on integration along trajectories which solve classical equations of motion. However in systems with higher dimension…
