X-ray Development of the Classical Nova V2672 Ophiuchi with Suzaku
D. Takei, M. Tsujimoto, J. J. Drake +1
We report the Suzaku detection of a rapid flare-like X-ray flux amplification early in the development of the classical nova V2672 Ophiuchi. Two target-of-opportunity ~25 ks X-ray…
Insulator-to-Superconductor Transition upon Electron Doping in a BiS-Based Superconductor SrLaFBiS
H. Sakai, D. Kotajima, K. Saito +6
Effects of electron doping on the BiS-based superconductors SrLaFBiS () have been investigated using the systematically synthesized polycrystals.…
Spectroscopic studies on the electronic and magnetic states of Co-doped perovskite manganite Pr0.8Ca0.2Mn1-yCoyO3 thin films
K. Yoshimatsu, H. Wadati, E. Sakai +13
We have investigated the electronic and magnetic properties of Co-doped Pr0.8Ca0.2MnO3 thin films using various spectroscopic techniques. X-ray absorption and hard x-ray photoemiss…
Single-shot 3D structure determination of nanocrystals with femtosecond X-ray free electron laser pulses
Rui Xu, Huaidong Jiang, Changyong Song +26
Coherent diffraction imaging (CDI) using synchrotron radiation, X-ray free electron lasers (X-FELs), high harmonic generation, soft X-ray lasers, and optical lasers has found broad…
Inversion Phenomena of the Anisotropies of the Hamiltonian and the Wave Function in Quantum Spin Chains
Kiyomi Okamoto
We investigate the inversion phenomena between the XXZ anisotropies of the Hamiltonian and the wave function in quantum spin chains. We focus on the S=1/2 geometrically frustrated…
Edge Modes in the Intermediate-D and Large-D Phases of the S=2 Quantum Spin Chain with XXZ and On-Site Anisotropies
Kiyomi Okamoto, Takashi Tonegawa, Toru Sakai +1
We investigate the edge modes at T=0 in the intermediate-D (ID) phase and the large-D (LD) phase of the S=2 quantum spin chain with the XXZ anisotropy and the generalized on-site a…
