Proposal for an optical laser producing light at half the Josephson frequency
Frans Godschalk, Fabian Hassler, Yuli V. Nazarov
We describe a superconducting device capable of producing laser light in the visible range at half of the Josephson generation frequency with the optical phase of the light locked…
Quantized conductance at the Majorana phase transition in a disordered superconducting wire
A. R. Akhmerov, J. P. Dahlhaus, F. Hassler +2
Superconducting wires without time-reversal and spin-rotation symmetries can be driven into a topological phase that supports Majorana bound states. Direct detection of these zero-…
Flat-lens focusing of electrons on the surface of a topological insulator
F. Hassler, A. R. Akhmerov, C. W. J. Beenakker
We propose the implementation of an electronic Veselago lens on the conducting surface of a three-dimensional topological insulator (such as Bi2Te3). The negative refraction needed…
Anyonic interferometry without anyons: How a flux qubit can read out a topological qubit
F. Hassler, A. R. Akhmerov, C. -Y. Hou +1
Proposals to measure non-Abelian anyons in a superconductor by quantum interference of vortices suffer from the predominantly classical dynamics of the normal core of an Abrikosov…
Dynamical Unbinding Transition in a Periodically Driven Mott Insulator
Fabian Hassler, Andreas Rüegg, Manfred Sigrist +1
We study the double occupancy in a fermionic Mott insulator at half-filling generated via a dynamical periodic modulation of the hopping amplitude. Tuning the modulation amplitude,…
Influence of a Random Telegraph Process on the Transport through a Point Contact
Fabian Hassler, Gordey B. Lesovik, Gianni Blatter
We describe the transport properties of a point contact under the influence of a classical two-level fluctuator. We employ a transfer matrix formalism allowing us to calculate arbi…
