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_…
Direct Observation of Local Magnetic Field Generated by Micromagnet
Shinji Watanabe, Susumu Sasaki, Shinya Sato +2
Using standard nuclear magnetic resonance (NMR) technique and a well-fabricated sample, we have succeeded in directly observing local magnetic field generated by a micro-magnet Ni4…
Relaxation of a Single Knotted Ring Polymer
Shinya Saka, Hiroshi Takano
The relaxation of a single knotted ring polymer is studied by Brownian dynamics simulations. The relaxation rate lambda_q for the wave number q is estimated by the least square fit…
Correlation Effects on Atom Density Profiles of 1-D and 2-D Polarized Atomic-Fermi-Gas Loaded on Optical Lattice
M. Machida, S. Yamada, M. Okumura +2
We investigate effects of optical lattice potential in one- and two-dimensional two-component trapped Fermi gases with population imbalances. Using the exact diagonalization and th…
Intersecting Solitons, Amoeba and Tropical Geometry
Toshiaki Fujimori, Muneto Nitta, Kazutoshi Ohta +2
We study generic intersection (or web) of vortices with instantons inside, which is a 1/4 BPS state in the Higgs phase of five-dimensional N=1 supersymmetric U(Nc) gauge theory on…
Noncommutative Deformation of Instantons
Yoshiaki Maeda, Akifumi Sako
We construct instanton solutions on noncommutative Euclidean 4-space which are deformations of instanton solutions on commutative Euclidean 4-space. We show that the instanton numb…
