Universal suppression of superfluid weight by disorder independent of quantum geometry and band dispersion
Alexander Lau, Sebastiano Peotta, Dmitry I. Pikulin +2
Motivated by the experimental progress in controlling the properties of the energy bands in superconductors, significant theoretical efforts have been devoted to study the effect o…
Geometric and conventional contribution to superfluid weight in twisted bilayer graphene
Xiang Hu, Timo Hyart, Dmitry I. Pikulin +1
By tuning the angle between graphene layers to specific "magic angles" the lowest energy bands of twisted bilayer graphene (TBLG) can be made flat. The flat nature of the bands fav…
Josephson current signatures of the Majorana flat bands on the surface of time-reversal-invariant Weyl and Dirac semimetals
Anffany Chen, D. I. Pikulin, M. Franz
A linear Josephson junction mediated by the surface states of a time-reversal-invariant Weyl or Dirac semimetal localizes Majorana flat bands protected by the time-reversal symmetr…
X-shaped and Y-shaped Andreev resonance profiles in a superconducting quantum dot
Shuo Mi, D. I. Pikulin, M. Marciani +1
The quasi-bound states of a superconducting quantum dot that is weakly coupled to a normal metal appear as resonances in the Andreev reflection probability, measured via the differ…
Fermion-parity anomaly of the critical supercurrent in the quantum spin-Hall effect
C. W. J. Beenakker, D. I. Pikulin, T. Hyart +2
The helical edge state of a quantum spin-Hall insulator can carry a supercurrent in equilibrium between two superconducting electrodes (separation L, coherence length xi). We calcu…
Phenomenology and Dynamics of Majorana Josephson Junction
D. I. Pikulin, Yuli V. Nazarov
We derive a generic phenomenological model of a Majorana Josephson junction that accounts for avoided crossing of Andreev states, and investigate its dynamics at constant bias volt…
