Effective Medium Theory (EMT) model based on the EMT implementation in ASAP (https://wiki.fysik.dtu.dk/asap). This model uses the asap_emt_driver model driver. Effective Medium Theory is a many-body potential of the same class as Embedded Atom Method, Finnis-Sinclair etc. The main term in the energy per atom is the local density of atoms. The functional form implemented here is that of Ref. 1. The principles behind EMT are described in Refs. 2 and 3 (with 2 being the more detailed and 3 being the most pedagogical). Be aware that the functional form and even some of the principles have changed since refs 2 and 3. EMT can be considered the last step of a series of approximations starting with Density Functional Theory, see Ref 4. This model implements a special parametrisation optimized for CuMg [5] and CuZr [6] bulk metallic glasses ONLY! Note that while this model might give reasonable results for other CuMg and CuZr compounds, it has not at all been optimized to give reasonable results for materials containing both Mg and Zr.

CHANGES: Changes in 002: * Bug fix: version 001 would crash with most tests/simulators due to an internal consistency test failing. * Bug fix: version 001 reported a slightly too short cutoff, leading to small inaccuracies (probably only for Au). * Bug fix: Memory leaks removed. * Enhancement: version 002 now supports ghost atoms (parallel simulations, many other tests). * Enhancement: version 002 now supports all neighbor list types, although the half lists give the best performance. KNOWN ISSUES / BUGS: * On-the-fly modifications of the parameters is not supported. It should be implemented. * More testing is needed.
