Tomonaga-Luttinger Liquid Renormalized by a Single Impurity
Kenji Kamide, Takashi Kimura, Susumu Kurihara
Effects of a single impurity potential on bulk properties of a spinful Tomonaga-Luttinger (TL) liquid is studied. A boundary bosonization technique is developed to include the impu…
Band-Selective Filter in a Zigzag Graphene Nanoribbon
Jun Nakabayashi, Daisuke Yamamoto, Susumu Kurihara
Electric transport of a zigzag graphene nanoribbon through a step-like potential or a barrier potential is investigated by using the recursive Green's function method. In the case…
Fano effect in a Josephson junction with a quantum dot
Kentaro Osawa, Susumu Kurihara, Nobuhiko Yokoshi
We theoretically investigate the Fano effect in dc Josephson current at the absolute zero of temperature. The system under consideration is a double-path Josephson junction in whic…
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…
Spin accumulation caused by confining potential in a two dimensional electron system
Kazuhisa Suzuki, Susumu Kurihara
We investigate spin accumulation caused by spin-orbit interactions (SOIs) in a two dimensional electron system confined in one direction. We calculate spin density caused by three…
Bosonization approach to the edge reconstruction of two dimentional electron systems in a quantum dot
Itaru Yanagi, Susumu Kurihara
We consider the edge reconstruction of electrons in a two dimensional harmonic trap under a strong magnetic field. In this system the edge reconstruction occurs as a result of comp…
