Electronic Structure of Superconducting FeSe Studied by High-Resolution Photoemission Spectroscopy
Rikiya Yoshida, Takanori Wakita, Hiroyuki Okazaki +13
We have performed soft x-ray and ultrahigh-resolution laser-excited photoemission measurements on tetragonal FeSe, which was recently identified as a superconductor. Energy depende…
A Lax Formalism for the Elliptic Difference Painlevé Equation
Yasuhiko Yamada
A Lax formalism for the elliptic Painlevé equation is presented. The construction is based on the geometry of the curves on and described in term…
Hyperbolic Deformation on Quantum Lattice Hamiltonians
Hiroshi Ueda, Tomotoshi Nishino
A group of non-uniform quantum lattice Hamiltonians in one dimension is introduced, which is related to the hyperbolic -dimensional space. The Hamiltonians contain only near…
Tricritical point of J1-J2 Ising model on hyperbolic lattice
R. Krcmar, T. Iharagi, A. Gendiar +1
A ferromagnetic-paramagnetic phase transition of the two-dimensional frustrated Ising model on a hyperbolic lattice is investigated by use of the corner transfer matrix renormaliza…
Measurement of single charged pion production in the charged-current interactions of neutrinos in a 1.3 GeV wide band beam
K2K Collaboration, A. Rodriguez, L. Whitehead
Single charged pion production in charged-current muon neutrino interactions with carbon is studied using data collected in the K2K long-baseline neutrino experiment. The mean ener…
Time-reversal symmetry breaking surface states of d-wave superconductors induced by an additional order parameter with negative T_c
Takeshi Tomizawa, Kazuhiro Kuboki
Surface states of d_{x^2-y^2}-wave superconductors are studied using the Ginzburg-Landau (GL) theory. For a [110] surface it has been known that the time-reversal symmetry (T) brea…
