Head of the Department of theoretical physics - Anatoly Konstantinovich Arzhnikov, PhD.

At present laboratory's staff contains 16 persons including 4 doctors and 9 candidates of sciences. Since 1989 the Head of the laboratory has been Anatoly Arzhnikov, doctor of sciences.

The principal lines of investigations are:

• The effect of disorder on the kinetic and magnetic properties, the spectra of electron and lattice quasiparticle excitations in alloys with chemical and topological disorder.
• Development of methods of "first-principles" calculations of spectral, electronic and phonon properties of low-dimensional (two-dimensional and semi-bounded) and partially disordered systems.
• Development of the method of molecular dynamics.
