Issp-center-dev/HPhi: Quantum Lattice Model Simulator Package

HΦ

A numerical solver package for a wide range of quantum lattice models including Hubbard-type itinerant electron hamiltonians, quantum spin models, and Kondo-type hamiltonians for itinerant electrons coupled with quantum spins. The Lanczos algorithm for finding ground states and newly developed Lanczos-based algorithm for finite-temperature properties of these models are implemented for parallel computing (hybrid parallelization with OpenMP and MPI). A broad spectrum of users including experimental researchers is cordially welcome.

Methods

Lanczos algorithm, thermal pure quantum state, full diagonalization

Target models

Hubbard model, Heisenberg model, Kondo lattice model, Kitaev model, Kitaev-Heisenberg model, multi-orbital Hubbard model

Available physical quantities

specific heat, susceptibility, ground state energy, free energy, structure factors

Requirement

C compiler (intel, Fujitsu, GNU, etc. ) LAPACK library (intel MKL, Fujitsu, ATLAS, etc.) MPI library (If you do not use MPI, it is not necessary.)

Install

You can install HΦ and also get a manual for HΦ from a release note.

Pre-Installed system

• System B of The Institute Solid State Physics jpint-use supercomputer (cleck here for details).
