Disorder-driven exceptional lines and Fermi ribbons in tilted nodal-line semimetals
Kristof Moors, Alexander A. Zyuzin, Alexander Yu. Zyuzin +2
We consider the impact of disorder on the spectrum of three-dimensional nodal-line semimetals. We show that the combination of disorder and a tilted spectrum naturally leads to a n…
Spin transport in a graphene normal-superconductor junction in the quantum Hall regime
Tibor Sekera, Christoph Bruder, Rakesh P. Tiwari
The quantum Hall regime of graphene has many unusual properties. In particular, the presence of a Zeeman field opens up a region of energy within the zeroth Landau level, where the…
Missing Shapiro steps and the -periodic Josephson effect in interacting helical electron systems
Christopher J. Pedder, Tobias Meng, Rakesh Tiwari +1
Two-particle backscattering in time-reversal invariant interacting helical electron systems can lead to the formation of quasiparticles with charge . We propose a way to detec…
Quantum Synchronization Blockade: Energy Quantization hinders Synchronization of Identical Oscillators
Niels Lörch, Simon E. Nigg, Andreas Nunnenkamp +2
Classically, the tendency towards spontaneous synchronization is strongest if the natural frequencies of the self-oscillators are as close as possible. We show that this wisdom fai…
Switchable valley filter based on a graphene - junction in a magnetic field
T. Sekera, C. Bruder, E. J. Mele +1
Low-energy excitations in graphene exhibit relativistic properties due to the linear dispersion relation close to the Dirac points in the first Brillouin zone. Two of the Dirac poi…
Robust quantum optimizer with full connectivity
Simon E. Nigg, Niels Loerch, Rakesh P. Tiwari
Quantum phenomena have the potential to speed up the solution of hard optimization problems. For example quantum annealing, based on the quantum tunneling effect, has recently been…
