Anomalous supercurrents in the presence of particle losses

Risa Ogino, Shun Uchino

We show that supercurrent properties in a superfluid or superconducting junction are significantly modified by single-particle losses in a conduction channel. In the presence of a…

Thermomagnetic anomalies in quantum magnon transport caused by tunable junction geometries in cold atomic systems

Yuta Sekino, Yuya Ominato, Hiroyuki Tajima +2

We study magnon-driven spin and heat transport in a magnetic linear junction (MLJ) formed by two ferromagnets in optical lattices linked via linearly aligned bonds. Using the Schwi…

Non-equilibrium dynamics of long-range interacting Fermions

Timo Zwettler, Giulia del Pace, Filip Marijanovic +12

A fundamental problem of out-of-equilibrium physics is the speed at which the order parameter grows upon crossing a phase transition. Here, we investigate the dynamics of ordering…

Thermomagnetic Anomalies by Magnonic Criticality in Ultracold Atomic Transport

Yuta Sekino, Yuya Ominato, Hiroyuki Tajima +2

We investigate thermomagnetic transport in an ultracold atomic system with two ferromagnets linked via a magnetic quantum point contact. Using nonequilibrium Green's function appro…

Particle current, noise, and counting statistics of quantum transport in the presence of a single-particle loss

Shun Uchino

How dissipation affects transport is an important theme in quantum science. Here we theoretically investigate an impact of a single-particle loss in mesoscopic transport, which has…

DC transport in a dissipative superconducting quantum point contact

Anne-Maria Visuri, Jeffrey Mohan, Shun Uchino +3

We study the current-voltage characteristics of a superconducting junction with particle losses at the contacts. We adopt the Keldysh formalism to compute the steady-state current…
