**Abstract**

We have recently developed open-source software HΦ. By using HΦ, users can perform the several exact calculations for a wide range of quantum lattice models, e.g., the exact diagonalization for the ground states, the finite-temperature calculations by the thermal pure quantum state, the calculations for the dynamical structure factors, and the real-time evolutions.

In this seminar, I will explain the basic properties and usages of HΦ. I will also show recent applications of HΦ to the finite-temperature properties of the frustrated Hubbard model and the finite-temperature magnetization in the Heisenberg model on the kagome lattice.
