PHYSBO is a Python library for researchers mainly in the materials science field to perform fast and scalable Bayesian optimization based on COMBO (Common Bayesian Optimization). Users can search the candidate with the largest objective function value from candidates listed in advance by using machine learning prediction. PHYSBO can handle a larger amount of data compared with standard implementations such as scikit-learn.
A Python library for manipulating symmetry operations and automatically generating symmetry-adapted multipole basis (SAMB) based on crystallographic point and space groups. By using QtDraw, users can also visualize the output of this library.
PAICS is a program of quantum chemical calculation. In this program, fragment molecular orbital (FMO) method is adopted, by which large molecules including biomolecular systems can be treated with several quantum chemical approaches including HF and MP2 methods. At the same time, PaicsView has been developed, which is a supporting program for making input files and analyzing calculation results.
A general-purpose open-source application for classical molecular dynamics simulation, distributed under the GPL license. This package can perform molecular dynamics calculation of various systems such as soft matters, solids, and mesoscopic systems. It can be used as a simulator of classical dynamics of realistic atoms as well as general model particles. It supports parallel computing through spatial divisions. Its codes are designed so that their modification and extension are easy.
Libxc is an library for exchange-correlation functions in the density functional theory. This has been developed for the purpose that well-tested exchange-correlation functions can be easily used in any DFT codes. In Libxc, users can find several types of exchange-correlation functions: LDA, GGA, hybrid-GGA, and meta-GGA.
DCA++ is a software framework to solve correlated electron problems with modern quantum cluster methods. This code provides a state of the art implementation of the dynamical cluster approximation (DCA) and its DCA+ extension. As the cluster solvers, DCA++ provides the continuous-time auxiliary field QMC (CT-AUX) , the continuous-time hybridization expansion (CT-HYB) restricted to single-site problems, the high temperature series expansion (HTS) and the exact diagonalization(ED).
Ising model and QUBO heuristic optimization library. The core of the optimization is implemented in C++; it has a Python interface, therefore it can be easily written in Python.
Tool for performing analytical continuation for many-body Green’s functions by using the maximum entropy method. From the data of the Green functions on the imaginary axis, users can obtain the values of the Green’s functions on the real axis. This tool supports the several different Green’s functions (Bozonic, Fermionic, anomalous, etc.).
MODYLAS is a highly parallelized general-purpose molecular dynamics (MD) simulation program appropriate for very large physical, chemical, and biological systems. It is equipped most standard MD techniques including free energy calculations based on thermodynamic integration method. Long-range forces are evaluated rigorously by the fast multipole method (FMM) without using the fast Fourier transform (FFT) in order to realize excellent scalability. The program enables investigations of large-scale real systems such as viruses, liposomes, assemblies of proteins and micelles, and polymers. It works on ordinary linux machines, too.
Parsec is a DFT program package based on real space basis and norm-conserving pseudopotential.
