AC Josephson current and supercurrent noise through one-dimensional correlated electron systems
Nobuhiko Yokoshi, Susumu Kurihara
AC Josephson effect in one-dimensional Tomonaga-Luttinger liquid (TLL) adiabatically connected to superconducting electrodes is theoretically investigated. It is found that density…
Collective Modes and Stability of Bose-Fermi Mixtures with a BCS-BEC Crossover
Hiroyuki Shibata, Nobuhiko Yokoshi, Susumu Kurihara
We investigate an ultracold Bose-Fermi mixture with a Feshbach resonance between two hyperfine states of fermions. Using a functional integral method, we calculate collective modes…
Josephson -state in superconductor-Luttinger liquid hybrid systems
Nobuhiko Yokoshi, Susumu Kurihara
Josephson current through a Luttinger liquid (LL) under a magnetic field is theoretically studied. We derive an analytical expression of Josephson current for clean interfaces, by…
Effects of fermion-boson interaction in neutral atomic systems
Nobuhiko Yokoshi, Susumu Kurihara
We investigate the collective excitations of He-He mixture films at zero temperature within random phase approximation and linear response theory. In low concentration regi…
