Surface Excitations, Energy Loss, and Decoherence in Electron Interferometry
David Kordahl
A recent pedagogical paper by Strauch concretely demonstrated how interaction-mediated entanglement can suppress fringe visibility in a one-dimensional model of the electron double…

Exploring Fourier methods with beer bottles
David Kordahl, Emma Foster
As anyone who has blown across the mouth of a beer bottle knows, beer bottles have a well-defined fundamental frequency. This paper shows how a beer bottle's acoustical resonance c…

Complementarity and entanglement in a simple model of inelastic scattering
David Kordahl
A simple model coupling a one-dimensional beam particle to a one-dimensional harmonic oscillator is used to explore complementarity and entanglement. This model, well-known in the…
