Gutzwiller study of spin-1 bosons in an optical lattice under a magnetic field
Takashi Kimura, Shunji Tsuchiya, Makoto Yamashita +1
We study spin-1 bosons in an optical lattice under a magnetic field by the Gutzwiller approximation. Our results thus obtained join the discontinuous phase boundary curves obtained…
Gravitational waves from a dust disk around a Schwarzschild black hole
Hajime Sotani, Motoyuki Saijo
We investigate gravitational waves from a dust disk around a Schwarzschild black hole to focus on whether we can extract any of its physical properties from a direct detection of g…
Superconductivity in Polycrystalline Diamond Thin Films
Yoshihiko Takano, Masanori Nagao, Tomohiro Takenouchi +4
Superconductivity was discovered in heavily boron-doped diamond thin films deposited by the microwave plasma assisted chemical vapor deposition (MPCVD) method. Advantages of the MP…
Origin of dielectric relaxation observed in complex perovskite oxides Ba(1-x)La(x)Ti(1-x)Cr(x)O3
Mamoru Fukunaga, Yoshiaki Uesu
Frequency dependence of the dielectric constant of complex perovskite oxide Ba(1-x)La(x)Ti(1-x)Cr(x)O3 (BLTC) ceramics with the composition ratio 0.4<= x <= 0.7 is precisely measur…
Notes on very ample vector bundles on 3-folds
Hidetoshi Maeda, Andrew Sommese
Let $\Cal E$ be a very ample vector bundle of rank two on a smooth complex projective threefold . An inequality about the third Segre class of $\Cal E$ is provided when $K_X+\de…
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…
