We theoretically predict proximity-induced odd-frequency (odd-ω) pairing on the surface of a Weyl nodal loop semimetal, characterized by a nodal loop Fermi surface and drumheadlike …

Abstract In recent times, Bogoliubov Fermi surfaces (BFSs) in superconductors (SCs) have drawn significant attention due to a substantial population of Bogoliubov quasiparticles …
We theoretically investigate the subgapped transport phenomena through a normal- superconductor-normal (NSN) junction made up of ultrathin topological insulator with …

We study the anomalous proximity effect in diffusive normal metal (DN)/unconventional superconductor junctions, where the local density of states (LDOS) in the DN has a zero …
We investigate the nonlocal transport properties in normal/superconducting/normal (NSN) junctions based on time-reversal symmetric type-I and type-II Weyl semimetals (WSMs). In …

We explore the phase-dependent charge and heat current in short Josephson junctions (JJs) with two normal metal regions attached at opposite ends, formed at helical edge states …

The existence of positive cross-correlated shot noise in superconducting nanowires indicates that a considerable fraction of electrons, in the electron current, violate Bell's …
LE Reichl - Physica B: Condensed Matter, 2020 - Elsevier
The shot noise associated with currents in NSN nanowires contains information about dynamical processes in the nanowire. Shot noise in photon currents is always positive due …

We theoretically investigate the transport properties of a quasi-one-dimensional ferromagnet- superconductor junction where the superconductor consists of mixed singlet and triplet …
