The program LmtART is an implementation of full-potential linear-muffin-tin-orbital method for electronic-structure calculations. It is designed to perform band structure, total energy and force calculations within the methods of density functional theory (DFT).

New version, LmtART 6.30, is now available. Its main features include:
 
(i) Local (spin) density approximation (LSDA) is avaiable in many parametrizations together with the gradient corrected density functionals (GGA91 and GGA96).
(ii) Multiple-kappa LMTO basis sets and multi-panel technique.
(iii) Total energy and force calculations for determining the equillibrium structure and phonons.
(iv) LDA+U method for strongly correlated systems.
(v) Spin-orbit coupling for heavy elements.
(vi) Finite temperatures
(vii) Full three dimensional treatment of magnetization in relativistic calculations including LDA+U.
(viii) Non-collinear magnetizm.
(ix) Tight-binding regime.
(x) Hoppings integrals extraction regime.
(xi) Optical Properties (e1,e2, reflectivity, electron energy loss spectra) using LMTO-ASA, LMTO full potential and tight-binding only regimes, with spin polarization, spin-orbit coupling, LDA+U included. (properly functioning when connected to MStudio MindLab software.)
(xii) Full 3D support for plotting charge densities & full potentials (properly functioning when connected to MStudio MindLab software.)
(xiii) Full 3D support for plotting Fermi surfaces (properly functioning when connected to MStudio MindLab software.)
(xiv) Full 3D support for plotting crystal strctures and orbitals (cubic/spherical harmonics) (properly functioning when connected to MStudio MindLab software.)


Following versions will include:
(a) Frequency dependent susceptibilities using LMTO-ASA, LMTO full potential and tight-binding only regimes, with spin polarization, spin-orbit coupling, LDA+U included.
(b) Dynamical mean-field theory for strongly correlated electronic systems.

The LmtART is written using FORTRAN 90 and uses fully dynamical memory scheme. No additional recompilations is required when changing numbers of atoms, spins, plane waves, lmax's, etc.

The input files to the LmtART involve in its simplest case only atomic charges of the atoms as well as crystal structure.

LmtART can run in the fast regimes such as using atomic sphere approximation. LmtART can also run using tight-binding mode. To use this mode, only hopping integrals have to be specified. LmtART can also be used to withdraw tight-binding parameters from LDA calculation since tight-binding LMTO basis set is implemented inside the code.

LmtART is a FREE scientific software. The bulk of the program has been developed at the Max-Planck Institute for Solid State Research in Stuttgart, Germany. The extensions of LmtART for strongly correlated systems were under developing in Department of Physics, Rutgers University, Department of Physics, New Jersey Institute of Technology, and now in Department of Physics, University of California, Davis.
