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…
Exactness of linear response in the quantum Hall effect
Sven Bachmann, Wojciech De Roeck, Martin Fraas +1
In general, linear response theory expresses the relation between a driving and a physical system's response only to first order in perturbation theory. In the context of charge tr…
Rational indices for quantum ground state sectors
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We consider charge transport for interacting many-body systems with a gapped ground state subspace which is finitely degenerate and topologically ordered. To any locality-preservin…
On the absence of stationary currents
Sven Bachmann, Martin Fraas
We review proofs of a theorem of Bloch on the absence of macroscopic stationary currents in quantum systems. The standard proof shows that the current in 1D vanishes in the large v…
