Shell structure and orbit bifurcations in finite fermion systems
A. G. Magner, I. S. Yatsyshyn, K. Arita +1
We first give an overview of the shell-correction method which was developed by V. M. Strutinsky as a practicable and efficient approximation to the general selfconsistent theory o…
LP Decodable Permutation Codes based on Linearly Constrained Permutation Matrices
Tadashi Wadayama, Manabu Hagiwara
A set of linearly constrained permutation matrices are proposed for constructing a class of permutation codes. Making use of linear constraints imposed on the permutation matrices,…
Multi-parametric Solution-path Algorithm for Instance-weighted Support Vector Machines
Masayuki Karasuyama, Naoyuki Harada, Masashi Sugiyama +1
An instance-weighted variant of the support vector machine (SVM) has attracted considerable attention recently since they are useful in various machine learning tasks such as non-s…
Phase Structure of Anisotropic Antiferromagnetic Heisenberg Model on Layered Triangular Lattice: Spiral State and Deconfined Spin Liquid
Kazuya Nakane, Takeshi Kamij, Ikuo Ichinose
In the present paper, we study spin- antiferromagnetic (AF) Heisenberg model on layered anisotropic triangular lattice and obtain its phase structure. We use the Schwi…
Antiferromagnetic, metal-insulator, and superconducting phase transitions in underdoped cuprates: Slave-fermion t-J model in the hopping expansion
Akihiro Shimizu, Koji Aoki, Kazuhiko Sakakibara +2
In the present paper, we study a system of doped antiferromagnet in three dimensions at finite temperatures by using the t-J model, a canonical model of strongly-correlated electro…
Study of Transient Nuclei near Freezing
Masaharu Isobe, Berni J. Alder
The molasses tail in dense hard core fluids is investigated by extensive event-driven molecular dynamics simulation through the orientational autocorrelation functions. Near the fl…
