Metric and arithmetic properties of mediant-Rosen maps
Cor Kraaikamp, Hitoshi Nakada, Thomas A. Schmidt
A continued fractions based verification of the Hurwitz values for the Hecke triangle groups is given, completing a program of Lehner's. Ergodic theory shows that Diophantine appro…
Multiband Superconductivity in Heavy Fermion Compound CePt3Si without Inversion Symmetry: An NMR Study on a High-Quality Single Crystal
H. Mukuda, S. Nishide, A. Harada +11
We report on novel superconducting characteristics of the heavy fermion (HF) superconductor CePt3Si without inversion symmetry through 195Pt-NMR study on a single crystal with T_c=…
Anomalous Hall voltage rectification and quantized spin-wave excitation induced by the simultaneous dc- and rf-current application in Ni81Fe19 wire
A. Yamaguchi, K. Motoi, A. Hirohata +1
An anomalous Hall effect and rectification of a Hall voltage are observed by applying a radio-frequency (rf) current through a single-layered ferromagnetic wire located on a coplan…
Stationary Phase and the Theory of Measurement -- 1/N expansion --
R. Fukuda
The measuring process is studied, where a macroscopic number N of particles in the detector interact with the object. The macrovariable accompanies the stationary phase in the path…
Dynamics of Strings between Walls
Minoru Eto, Toshiaki Fujimori, Takayuki Nagashima +3
Configurations of vortex-strings stretched between or ending on domain walls were previously found to be 1/4 Bogomol'nyi-Prasad-Sommerfield(BPS) states in N=2 supersymmetric gauge…
Multicanonical Algorithm, Simulated Tempering, Replica-Exchange Method, and All That
Ayori Mitsutake, Yuko Okamoto
We discuss multi-dimensional generalizations of multicanonical algorithm, simulated tempering, and replica-exchange method. We generalize the original potential energy function $E_…
