Accurate estimation of interface phase diagram from STM images
Kazuhito Takeuchi, Koretaka Yuge, Shinya Tabata +3
We propose a new approach to constructing a phase diagram using the effective Hamiltonian derived only from a single real-space image produced by scanning tunneling microscopy (STM…
First-principles Study on Formation of LPSO Structures for Ternary Alloys Revisited from Short-range Order
Koretaka Yuge, Hisashi Miyazono, Ryohei Tanaka +2
We investigate the formation of long-period stacking ordered (LPSO) structure for Mg-Y-Zn ternary alloys based on the short-range order (SRO) tendency of energetically competitive…
A new Wang-Landau approach to obtain phase diagrams for multicomponent alloys
Kazuhito Takeuchi, Ryohei Tanaka, Koretaka Yuge
We develop an approach to apply Wang-Landau algorithm to multicomponent alloys in semi-grand-canonical ensemble. Although the Wang-Landau algorithm has great advantages over conven…
Extension of structure integration to magnetic system
Kazuhito Takeuchi, Takashi Ishikawa, Ryohei Tanaka +1
We extend our previously developed method, "structure integration", to evaluate free energy directly for magnetic large systems on given lattice. The present method express the den…
Direct evaluation of free energy for large system through structure integration approach
Kazuhito Takeuchi, Ryohei Tanaka, Koretaka Yuge
We propose a new approach, "structure integration", enabling direct evaluation of configurational free energy for large systems. The present approach is based on the statistical in…
