ESpinS - Esfahan Spin Simulation package

Package for classical Monte-Carlo simulation of spin systems. In ESpinS, the spin model hamiltonian of a spin system can be defined through the Heisenberg exchange, bi-quadratic, Dzyaloshinskii-Moriya, and single-ion interactions. Spin configurations can be updated through either local Metropolis updating or parallel tempering.

Requirements

The package requires the following software:

• Fortran 90 compiler, such as GFortran or IFORT
• BLAS and LAPACK library
• MPI libray (openmpi)

Installing

• Intel oneAPI Base Toolkit
• Intel oneAPI HPC Toolkit

is an easy way to have all the necessary packages.

Installation

git clone https://github.com/nafiserb/ESpinS.git
cd ESpinS
make

In the case that compilation process encounters errors, please edit make.sys file. For more information about installation please see user-guide.
