Dynamical structure factor in the non-Abelian phase of the Kitaev honeycomb model in the presence of quenched disorder
Daniel Otten, Ananda Roy, Fabian Hassler
Kitaev's model of spins interacting on a honeycomb lattice describes a quantum spin-liquid, where an emergent static gauge field is coupled to Majorana fermions. In…
Korshunov instantons in a superconductor at elevated bias current
Daniel Otten, Fabian Hassler
Dissipation even at zero temperature reduces quantum fluctuations and tends to localize particles. A notable exception is the nonlinear dissipation due to quasiparticle tunneling i…
Universal power-law decay of electron-electron interactions due to nonlinear screening in a Josephson junction array
Daniel Otten, Sebastian Rubbert, Jascha Ulrich +1
Josephson junctions are the most prominent nondissipative and at the same time nonlinear elements in superconducting circuits allowing Cooper pairs to tunnel coherently between two…
Second-order coherence of microwave photons emitted by a quantum point contact
Fabian Hassler, Daniel Otten
Shot-noise of electrons that are transmitted with probability through a quantum point contact (biased at a voltage ) leads to a fluctuating current that in turn emits radi…
Simulation of supersymmetric quantum mechanics in a Cooper-pair box shunted by a Josephson rhombus
Jascha Ulrich, Daniel Otten, Fabian Hassler
Supersymmetries in quantum mechanics offer a way to obtain degeneracies in the excitation spectrum which do not originate from selection rules. The mechanism behind the degeneracie…
