Charge response of the Majorana toric code
Ananda Roy, Fabian Hassler
At zero temperature, a two dimensional lattice of Majorana zero modes on mesoscopic superconducting islands has a topologically ordered toric code phase. Recently, a Landau field t…
Aharonov-Bohm oscillations and magnetic focusing in ballistic graphene rings
Jan Dauber, Martin Oellers, Florian Venn +5
We present low-temperature magnetotransport measurements on graphene rings encapsulated in hexagonal boron nitride. We investigate phase-coherent transport and show Aharonov-Bohm (…
Quantum phase transitions of the Majorana toric code in the presence of finite Cooper-pair tunneling
Ananda Roy, Barbara M. Terhal, Fabian Hassler
The toric code based on Majorana fermions on mesoscopic superconducting islands is a promising candidate for quantum information processing. In the limit of vanishing Cooper-pair t…
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…
