A paper using HΦ “Sublattice Coding Algorithm and Distributed Memory Parallelization for Large-Scale Exact Diagonalizations of Quantum Many-Body Systems” is published !

In this paper(arXiv:1804.05028, Phys. Rev. E 98, 033309 (2018)), they propose a efficient method
for performing the exact diagonalization.
As a demonstration, they perform the exact diagonalization
up to 50 site spin-1/2 Heisenberg model.
As a typical software that implements
parallelized exact diagonalization,
they cite HΦ.
