Laser-driven high-power X- and gamma-ray ultra-short pulse source
Timur Zh. Esirkepov, Sergei V. Bulanov, Alexei G. Zhidkov +2
A novel ultra-bright high-intensity source of X-ray and gamma radiation is suggested. It is based on the double Doppler effect, where a relativistic flying mirror reflects a counte…
Universal versus Material-Dependent Two-Gap Behaviors in the High-Tc Cuprates: Angle-Resolved Photoemission Study of La2-xSrxCuO4
T. Yoshida, M. Hashimoto, S. Ideta +11
We have investigated the doping and temperature dependences of the pseudogap/superconducting gap in the single-layer cuprate LaSrCuO by angle-resolved photoemission…
Appearance of Universal Metallic Dispersion in a Doped Mott Insulator
S. Sahrakorpi, R. S. Markiewicz, Hsin Lin +16
We have investigated the dispersion renormalization in LaSrCuO (LSCO) over the wide doping range of , for binding energies extending to seve…
Doping evolution of the electronic specific heat coefficient in slightly-doped La2-xSrxCuO4 single crystals
Seiki Komiya, I. Tsukada
Detailed doping dependence of the electronic specific heat coefficient gamma is studied for La2-xSrxCuO4 (LSCO) single crystals in the slightly-doped regime. We find that gamma sys…
Ab initio investigation on oxygen defect clusters in UO2+x
Hua Y. Geng, Ying Chen, Yasunori Kaneta +1
By first-principles LSDA+U calculations, we revealed that the current physical picture of defective uranium dioxide suggested solely by neutron diffraction analysis is unsatisfacto…
Stability mechanism of cuboctahedral clusters in UO2: First-principles calculations
Hua Y. Geng, Ying Chen, Yasunori Kaneta +1
The stability mechanism of cuboctahedral clusters in nonstoichiometric uranium dioxide is investigated by first-principles LSDA+U method. Calculations reveal that the structural st…
Point defects and clustering in uranium dioxide by LSDA+U calculations
Hua Y. Geng, Ying Chen, Yasunori Kaneta +3
A comprehensive investigation on point defects and their clustering behavior in nonstoichiometric uranium dioxide UO2+x is carried out using LSDA+U method based on density function…
Beta-decay branching ratios of 62Ga
A. Bey, B. Blank, G. Canchel +20
Beta-decay branching ratios of 62Ga have been measured at the IGISOL facility of the Accelerator Laboratory of the University of Jyvaskyla. 62Ga is one of the heavier Tz = 0, 0+ ->…
Electronic Origin of the Inhomogeneous Pairing Interaction in the High-Tc Superconductor Bi2Sr2CaCu2O8+d
Abhay N. Pasupathy, Aakash Pushp, Kenjiro K. Gomes +7
Identifying the mechanism of superconductivity in the high-temperature cuprate superconductors is one of the major outstanding problems in physics. We report local measurements of…
Successive phase transitions to antiferromagnetic and weak-ferromagnetic long-range orders in quasi-one-dimensional antiferromagnet CuMoO
Tomoaki Hamasaki, Tomoyuki Ide, Haruhiko Kuroe +4
Investigation of the magnetism of CuMoO single crystal, which has antiferromagnetic (AF) linear chains interacting with AF dimers, reveals an AF second-order phase tran…
Doping dependence of phonon and quasiparticle heat transport of pure and Dy-doped Bi_2Sr_2CaCu_2O_{8+δ} single crystals

X. F. Sun, A. A. Taskin, X. Zhao +2
To study the effects of paramagnetic spins on phonons, both the in-plane and the c-axis heat transport of GdBaCo_{2}O_{5+x} (GBCO) single crystals are measured at low temperature d…
Inhomogeneous Magnetic-Field Response of YBa2Cu3Oy and La2-xSrxCuO4 Persisting above the Bulk Superconducting Transition Temperature
J. E. Sonier, M. Ilton, V. Pacradouni +8
We report that in YBa2Cu3Oy and La2-xSrxCuO4 there is a spatially inhomogeneous response to magnetic field for temperatures T extending well above the bulk superconducting transiti…
