Band edge limit of the scattering matrix for quasi-one-dimensional discrete Schrödinger operators
Miguel Ballesteros, Gerardo Franco Córdova, Guillermo Garro +1
This paper is about the scattering theory for one-dimensional matrix Schrödinger operators with a matrix potential having a finite first moment. The transmission coefficients are a…

The appearance of particle tracks in detectors
Miguel Ballesteros, Tristan Benoist, Martin Fraas +1
The phenomenon that a quantum particle propagating in a detector, such as a Wilson cloud chamber, leaves a track close to a classical trajectory is analyzed. We introduce an ideali…
