In 1972,Laboratory of Theoretical Physics was established as one division of the Institute of Physics and Technology, Mongolian Academy of Sciences. Now the department does world-class research ona wide range of topics in theoretical physics including quantum field theory, elementary particles and nuclear interactions, quantum chromodynamics and mathematical methods for physics cooperating with international scientific organizations.

Since its establishment, more than 20 books, monographs, textbooks and over 1500 scientific papers have been published. Current research group in the department includes one academician, 2 Ph.Ds and 3M.Scgraduates.

Academician Kh.Namsrai, a head of the department, was awarded with “Prize in Natural and Social Sciences” in areas of science and technology in 2012, and the supreme state prize of Mongolia “the Order of ChinggisKhaan” in 2014 in recognition of his distinguished contribution to physics.
