Voltage staircase in a current-biased quantum-dot Josephson junction
D. O. Oriekhov, Y. Cheipesh, C. W. J. Beenakker
We calculate the current-voltage (I-V) characteristic of a Josephson junction containing a resonant level in the weakly coupled regime (resonance width small compared to the superc…
Gap generation and flat band catalysis in dice model with local interaction
E. V. Gorbar, V. P. Gusynin, D. O. Oriekhov
The gap generation in the dice model with local four-fermion interaction is studied. Due to the presence of two valleys with degenerate electron states, there are two main types of…
Half-integer charge injection by a Josephson junction without excess noise
F. Hassler, A. Grabsch, M. J. Pacholski +4
A Josephson junction in a topological superconductor can inject a charge e/2 into a normal-metal contact, carried by chiral Majorana edge modes. Here we address the question whethe…
RKKY interaction in a doped pseudospin-1 fermion system at finite temperature
D. O. Oriekhov, V. P. Gusynin
We study the RKKY interaction of magnetic impurities in the model which hosts pseudospin-1 fermions with two dispersive and one flat bands. By using the effective…
Plasmon Resonances and Tachyon Ghost Modes in Highly Conducting Sheets
D. O. Oriekhov, L. S. Levitov
Plasmon-polariton modes in two-dimensional electron gases have a dual field-matter nature that endows them with unusual properties when electrical conductivity exceeds a certain th…
Electron states for gapped pseudospin-1 fermions in the field of charged impurity
E. V. Gorbar, V. P. Gusynin, D. O. Oriekhov
The electron states of gapped pseudospin-1 fermions of the lattice in the Coulomb field of a charged impurity are studied. The free model has three di…
