Bohr--Sommerfeld rules for systems
Simon Becker, Setsuro Fujiié, Jens Wittsten
We present a complete, self-contained formulation of the Bohr--Sommerfeld quantization rule for a semiclassical self-adjoint system on the real line, arising from a si…

Discrete vs. continuous in the semiclassical limit
Simon Becker, Jens Wittsten, Maciej Zworski
We compare the bottom of the spectrum of discrete and continuous Schrödinger operators with periodic potentials with barriers at the boundaries of their fundamental domains. Our re…
