Abstract
We report the development of a new code which is designed for the combined analysis of correlated electronic structure and magnetism. First, the program provides the self-consistent dynamical mean-field theory solution with its own exact diagonalization ‘solver’. By means of the easy-to-use controllable interface to the external ‘solvers’, it is also capable of conducting quantum Monte Carlo based dynamical mean-field theory calculations. Second, performs magnetic force response theory to compute magnetic coupling constants. As its input Hamiltonian can be constructed from first-principles density functional theory typically through Wannier-type projections, it can serve as a useful tool for studying correlated magnetic materials. Finally, it provides the internal mode of computing spin wave dispersion based on semi-classical approximation. Benchmark calculation results on several prototypical materials are presented together with the details of usage.

期刊介绍:
The focus of CPC is on contemporary computational methods and techniques and their implementation, the effectiveness of which will normally be evidenced by the author(s) within the context of a substantive problem in physics. Within this setting CPC publishes two types of paper.
Computer Programs in Physics (CPiP)
These papers describe significant computer programs to be archived in the CPC Program Library which is held in the Mendeley Data repository. The submitted software must be covered by an approved open source licence. Papers and associated computer programs that address a problem of contemporary interest in physics that cannot be solved by current software are particularly encouraged.
Computational Physics Papers (CP)
These are research papers in, but are not limited to, the following themes across computational physics and related disciplines.
mathematical and numerical methods and algorithms;
computational models including those associated with the design, control and analysis of experiments; and
algebraic computation.
Each will normally include software implementation and performance details. The software implementation should, ideally, be available via GitHub, Zenodo or an institutional repository.In addition, research papers on the impact of advanced computer architecture and special purpose computers on computing in the physical sciences and software topics related to, and of importance in, the physical sciences may be considered.
