Topological Josephson junction in transverse magnetic field
Stefan Backens, Alexander Shnirman, Yuriy Makhlin
We consider Majorana zero modes in a Josephson junction on top of a topological insulator in transverse magnetic field. Majorana zero modes reside at periodically located nodes of…
Current--phase relation in a topological Josephson junction: Andreev bands vs. scattering states
Stefan Backens, Alexander Shnirman
We consider a long topological Josephson junction formed on a conducting 2D surface of a 3D topological insulator (TI). The superconducting correlations are proximity-induced by s-…
Excess equilibrium noise in topological SNS junction between chiral Majorana liquids
Dmitriy S. Shapiro, Alexander D. Mirlin, Alexander Shnirman
We consider a Josephson contact mediated by 1D chiral modes on a surface of a 3D topological insulator with superimposed superconducting and magnetic layers. The system represents…
Insulating Josephson-junction chains as pinned Luttinger liquids
Karin Cedergren, Roger Ackroyd, Sergey Kafanov +3
Quantum physics in one spatial dimension is remarkably rich, yet even with strong interactions and disorder, surprisingly tractable. This is due to the fact that the low-energy phy…
Decoherence spectroscopy with individual two-level tunneling defects
Jürgen Lisenfeld, Alexander Bilmes, Shlomi Matityahu +7
Recent progress with microfabricated quantum devices has revealed that an ubiquitous source of noise originates in tunneling material defects that give rise to a sparse bath of par…
Current-phase relation and -periodic critical current of a chiral Josephson contact between 1D Majorana modes
Dmitriy S. Shapiro, Alexander Shnirman, Alexander D. Mirlin
We explore a long Josephson contact transporting Cooper pairs between 1D charge-neutral chiral Majorana modes in the leads via charged Dirac chiral modes in the normal region. We i…
