Karen V. Ter‑Martirosyan (also transliterated as Karen Ter‑Martirosian) was a Soviet‑Armenian theoretical physicist noted for his contributions to quantum field theory and the theory of few‑body systems. His work is most frequently cited in connection with the Skornyakov–Ter‑Martirosyan (STM) equation, derived in 1957 with G. V. Skornyakov, which describes three‑particle scattering in the limit of zero‑range interactions and laid groundwork for later developments such as Efimov physics.
Career and research
- Ter‑Martirosyan worked at leading Soviet research institutions, including the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, where he conducted research on scattering theory, nuclear reactions, and relativistic quantum mechanics.
- He published a series of influential papers on the analytic properties of scattering amplitudes, the renormalization of quantum electrodynamics, and the application of dispersion relations in particle physics.
- The STM equation bearing his name remains a standard tool in few‑body physics and is routinely referenced in modern theoretical and experimental studies of ultracold atomic gases and nuclear three‑body problems.
Recognition
- He was a member of the Russian Academy of Sciences and received various state honors for his scientific achievements. Specific award details are not comprehensively documented in widely available encyclopedic sources.
Biographical data
- Precise dates of birth and death, as well as details of his early education, are not consistently recorded in mainstream reference works. Consequently, those aspects of his biography remain insufficiently documented in publicly accessible encyclopedic material.
The information presented reflects established, verifiable contributions of Karen Ter‑Martirosyan to theoretical physics, as documented in scientific literature and recognized academic references.
