Extracting the anyonic exchange phase from co-tunneling through an open quantum dot
Felix Puster, Matthias Thamm, Bernd Rosenow
The elementary excitations of fractional quantum Hall states obey anyonic statistics, described by an exchange phase intermediate between the bosonic and fermionic values. We s…
Schrödinger's real-valued equation revisited
Oliver Passon, Bernd Rosenow
The Schrödinger equation can be rewritten as a second-order equation for a single real-valued scalar field. Taken at face value, however, this one-field reduction obscures several…
Anyon Exchange Phase from Antidot Interferometry
Matthias Thamm, Felix Puster, Bernd Rosenow
Quasiparticles in fractional quantum Hall systems are anyons, carrying a fraction of the electron charge. Exchanging two of them gives rise to a fractional exchange phase. While th…
Learning Dynamics of Chain-of-Thought State Tracking in a Solvable Transformer Model
Niklas Forner, Marcel Kühn, Matthias Thamm +1
Chain-of-thought generation can turn a multi-step computation into a sequence of locally checkable state updates, but the training dynamics by which transformers acquire such updat…
Extracting the Anyonic Exchange Phase from Hanbury Brown-Twiss Correlations
Felix Puster, Matthias Thamm, Bernd Rosenow
In recent years, interferometry experiments in fractional quantum Hall devices have reported signatures of a fractional braiding phase for quasiparticles. It was noted, however, th…
Braids and Beams: Exploring Fractional Statistics with Mesoscopic Anyon Colliders
Bernd Rosenow, Bertrand I. Halperin
Anyon colliders -- quantum Hall devices where dilute quasiparticle beams collide at a quantum point contact -- provide an interferometer-free probe of anyonic exchange phases throu…
