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…
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…
Invariant measure for stochastic Schrödinger equations
Tristan Benoist, Martin Fraas, Yan Pautrat +1
Quantum trajectories are Markov processes that describe the time-evolution of a quantum system undergoing continuous indirect measurement. Mathematically, they are defined as solut…
Note on linear response for interacting Hall insulators
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We relate explicitly the adiabatic curvature -- in flux space -- of an interacting Hall insulator with nondegenerate ground state to various linear response coefficients, in partic…
A many-body index for quantum charge transport
Sven Bachmann, Alex Bols, Wojciech De Roeck +1
We propose an index for pairs of a unitary map and a clustering state on many-body quantum systems. We require the map to conserve an integer-valued charge and to leave the state,…
