Short-Range-Order for fcc-based binary alloys Revisited from Microscopic Geometry
Koretaka Yuge
Short-range order (SRO) in disordered alloys is typically interpreted as competition between chemical effect of negative (or positive) energy gain by mixing constituent elements an…
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…
Landscape of Configurational Density of States for Discrete Large Systems
Koretaka Yuge, Tetsuya Taikei, Kazuhito Takeuchi
For classical many-body systems, our recent study reveals that expectation value of internal energy, structure, and free energy can be well characterized by a single specially-sele…
Microscopic Geometry Characterizes Structure/Potential-Energy Correspondence in a Thermodynamic System
Koretaka Yuge
Potential energy landscape (PEL) is essential to determine phase stability, reaction path, and other important physical as well as chemical properties. Whereas given PEL can reason…
Universality of density of states in configuration space
Tetsuya Taikei, Kazuhito Takeuchi, Koretaka Yuge
In this study, we confirm the universality of density of microscopic states in non-interacting system; this means statistical interdependence is vanished in any lattices. This enab…
Analytic Determination of Variance for Configurational Density of States in Crystalline Solids
Tetyuya Taikei, Kazuhito Takeuchi, Koretaka Yuge
Our recent study elucidate that information of density of states in configuration space (CDOS) for non-interacting system, characterized by spatial constraint on the system, plays…
Extended Configurational Polyhedra Based on Graph Representation for Crystalline Solids
Koretaka Yuge
We propose theoretical approach based on combination of graph theory and generalized Ising model (GIM), which enables systematic determination of extremal structures for crystallin…
