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…
