Strong-coupling Effects in cuprate High- Superconductors by magnetooptical studies
Y. S. Lee, Z. Q. Li, W. J. Padilla +5
Signatures of strong coupling effects in cuprate high- superconductors have been authenticated through a variety of spectroscopic probes. However, the microscopic nature of…
Hall effect of quasi-hole gas in organic single-crystal transistors
J. Takeya, K. Tsukagoshi, Y. Aoyagi +2
Hall effect is detected in organic field-effect transistors, using appropriately shaped rubrene (C42H28) single crystals. It turned out that inverse Hall coefficient, having a posi…
Electronic Inhomogeneity and Breakdown of the Universal Thermal Conductivity in Cuprate Superconductors
X. F. Sun, S. Ono, Yasushi Abe +3
We report systematic, high-precision measurements of the low-T (down to 70 mK) thermal conductivity κof YBa_{2}Cu_{3}O_{y}, La_{2-x}Sr_{x}CuO_{4} and Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}. C…
Constituents of the "kink" in high-Tc cuprates
A. A. Kordyuk, S. V. Borisenko, V. B. Zabolotnyy +9
Applying the Kramers-Kronig consistent procedure, developed earlier, we investigate in details the formation of the quasiparticle spectrum along the nodal direction of high-Tc cupr…
Doping Evolution of the Underlying Fermi Surface in La2-xSrxCuO4
T. Yoshida, X. J. Zhou, K. Tanaka +9
We have performed a systematic doping dependent study of LaSrCuO (LSCO) (0.030.3) by angle-resolved photoemission spectroscopy. In the entire doping ra…
Magnetic and Charge Correlations in La{2-x-y}Nd_ySr_xCuO_4: Raman Scattering Study
A. Gozar, Seiki Komiya, Yoichi Ando +1
Two aspects in connection with the magnetic properties of La_{2-x-y}Nd_ySr_xCuO_4 single crystals are discussed. The first is related to long wavelength magnetic excitations in x =…
Theory of Recurrent Neural Network with Common Synaptic Inputs
Masaki Kawamura, Michiko Yamana, Masato Okada
We discuss the effects of common synaptic inputs in a recurrent neural network. Because of the effects of these common synaptic inputs, the correlation between neural inputs cannot…
Electron-Hole Asymmetry in GdBaCo_{2}O_{5+x}: Evidence for Spin Blockade of Electron Transport in a Correlated Electron System
A. A. Taskin, Yoichi Ando
In RBaCo_{2}O_{5+x} compounds (R is rare earth) variability of the oxygen content allows precise doping of CoO_2 planes with both types of charge carriers. We study transport prope…
