Thermopower analysis of metal-insulator transition temperature modulations in vanadium dioxide thin films with lattice distortion
Takayoshi Katase, Kenji Endo, Hiromichi Ohta
Insulator-to-metal (MI) phase transition in vanadium dioxide (VO2) thin films with controlled lattice distortion was investigated by thermopower measurements. VO2 epitaxial films w…
A rigorous setting for the reinitialization of first order level set equations
Nao Hamamuki, Eleftherios Ntovoris
In this paper we set up a rigorous justification for the reinitialization algorithm. Using the theory of viscosity solutions, we propose a well-posed Hamilton-Jacobi equation with…
Mass Estimates of a Giant Planet in a Protoplanetary Disk from the Gap Structures
Kazuhiro D. Kanagawa, Takayuki Muto, Hidekazu Tanaka +4
A giant planet embedded in a protoplanetary disk forms a gap. An analytic relationship among the gap depth, planet mass , disk aspect ratio , and viscosity has been…
Near-IR High-Resolution Imaging Polarimetry of the SU Aur Disk: Clues for Tidal Tails?
Jerome de Leon, Michihiro Takami, Jennifer L. Karr +53
We present new high-resolution (0\farcs09) -band imaging observations of the circumstellar disk around the T Tauri star SU Aur. Our observations with Subaru-HiCIAO have re…
Polaron transport and thermoelectric behavior in La-doped SrTiO3 thin films with elemental vacancies
Woo Seok Choi, Hyang Keun Yoo, Hiromichi Ohta
Electrodynamic properties of La-doped SrTiO3 thin films with controlled elemental vacancies have been investigated using optical spectroscopy and thermopower measurement. In partic…
OISTER Optical and Near-Infrared Observations of Type Iax Supernova 2012Z
Masayuki Yamanaka, Keiichi Maeda, Koji S. Kawabata +30
We report observations of the Type Iax supernova (SN Iax) 2012Z at optical and near-infrared wavelengths from immediately after the explosion until days after the maxi…
