A Simple Scheme to Entangle Distant Qubits from a Mixed State via an Entanglement Mediator
Kazuya Yuasa, Hiromichi Nakazato
A simple scheme to prepare an entanglement between two separated qubits from a given mixed state is proposed. A single qubit (entanglement mediator) is repeatedly made to interact…
Spin-charge mixing effects on resonant tunneling in a polarized Luttinger Liquid
Kenji Kamide, Yuji Tsukada, Susumu Kurihara
We investigate spin-charge mixing effect on resonant tunneling in spin-polarized Tomonaga-Luttinger liquid with double impurities. The mixing arises from Fermi velocity difference…
Initial state maximizing the nonexponentially decaying survival probability for unstable multilevel systems
Manabu Miyamoto
The long-time behavior of the survival probability for unstable multilevel systems that follows the power-decay law is studied based on the N-level Friedrichs model, and is shown t…
A Chandra Deep X-ray Exposure on the Galactic Plane and Near Infrared Identification
K. Ebisawa, A. Paizis, T. J. -L. Couvoisier +13
Using the Chandra ACIS-I instruments, we have carried out a deep X-ray observation on the Galactic plane region at (l,b) ~ (28.5, 0.0), where no discrete X-ray sources have been kn…
Large positive magnetic susceptibility of nanotube torus
Ryo Tamura, Mitsuhiro Ikuta, Toru Hirahara +1
We calculate the magnetic moment caused by the persistent currents in polygonal carbon nanotube tori by the tight binding model. The polygonal CNT tori are formed by introducing he…
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…
