Tensor Renormalization Group Calculations of Partition-Function Ratios

The behavior of dimensionless quantities defined as ratios of partition functions is analyzed to investigate phase transitions and critical phenomena. At criticality, the universal values of these ratios can be predicted from conformal field theory (CFT) through the modular-invariant partition functions on a torus. We perform numerical calculations using the bond-weighted tensor renormalization group for three two-dimensional models belonging to different universality classes: the Ising model, the three-state Potts model, and the four-state Potts model. The partition-function ratios obey the same finite-size scaling form as the Binder parameter, and their critical values agree well with the universal values predicted by CFT. In the four-state Potts model, we observe logarithmic corrections in the system-size dependence of these ratios.

VASP inputs and trajectory analysis programs for Ba-Li oxyhydrides

First-principles molecular dynamics simulation data for Ba-Li oxyhydride by VASP and additional fortran and python programs for output trajectory files.

Model parameters for the ambient-pressure organic Dirac electron state in α-(BETS)₂AuCl₂

This repository contains model parameters for the tight-binding description of the ambient-pressure Dirac electron state in α-(BETS)₂AuCl₂.
These parameters are constructed to reproduce the quasi-three-dimensional massive Dirac semimetal electronic structure identified by first-principles calculations including spin–orbit coupling, and are intended for reuse in theoretical and computational studies.

Mitigating proton trapping in cubic perovskite oxides via ScO6 octahedral networks

Molecular dynamics trajectory for proton diffusion in heavily Sc-doped BaSnO3, the force field used for the simulation, and training data for the machine-learning force field.

ODAT-SE gallery

Open Data Analysis Tool for Science and Engineering (ODAT-SE) is a framework for applying a search algorithm to a direct problem solver to find the optimal solution. It has been developed by the name 2DMAT, and since version 3.0, it is organized as an open platform for data analysis by modularizing direct problem solvers and search algorithms.
This repository is a collection of examples for ODAT-SE.
