Lecturer Intro
Hrachya Babujian (Babujyan) received his PhD from L. D. Landau Institute of Theoretical Physics in Moscow, where he was PhD student of A.A. Belavin. The Habilitation he get in Yerevan Physics Institute (Alikhanyan National Lab) where he currently holds the title Leading Scientific Researcher. In the 1990’s he was working in Bonn University and Berlin FU where he enjoy the Mathematical Physics group of R. Schrader. He also work in Sao Carlos University (Brazil) in Brookhaven National Lab, Simons Center and Chicago University. H. Babujian’s research interests are in Integrability in 2d statistical models and 1+1 dimensional quantum field theories, 1d spin chains, conformal blocks, form factors and thermodynamics of integrable models. Now his interest is the applications of the exact form factors in 1+3 dimensional lepton-hadron scattering in small Bjorkan x case.
