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 LOBPCG 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.
Lanczos algorithm, thermal pure quantum state, full diagonalization
Hubbard model, Heisenberg model, Kondo lattice model, Kitaev model, Kitaev-Heisenberg model, multi-orbital Hubbard model
specific heat, susceptibility, ground state energy, free energy, structure factors
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.)
You can install HHPhi++ and also get a manual for HPhi++ from a release note.
- System B of The Institute Solid State Physics jpint-use supercomputer (cleck here for details).
