Renata Kallosh
Renata Ernestowna Kallosch (Russian Рената Эрнестовна Каллош, English transliteration Kallosh, * 1943) is a Russian - American theoretical physicist, mainly on quantum field theory ( supersymmetry, string theory / M-theory, supergravity ) works.
Kallosch graduated in 1966 at the Moscow State University and received his doctorate in 1968 at the Lebedev Institute in Moscow. 1981 to 1989 she was a professor there. 1989 to 1990 she was at CERN and from 1990 professor at Stanford.
Kallosch worked in the 1970s on the quantization of Yang-Mills theories with the Background Field Method of Bryce DeWitt and Feynman rules for supergravity and in the 1980s, for example, on the quantization of superstrings. She became famous in the 1990s for the study of special supersymmetric black holes where then succeeded the microscopic derivation of the Bekenstein - Hawking entropy. Kallosh could prove a lower limit of the mass of the supersymmetric charges and found evidence of attractor mechanisms. Recently, they studied the early universe and dark energy in string theory / M- theory and supergravity .. With Shamit Kachru, lime and Sandip Trivedi she developed in 2003 the KKLT scenario of string cosmology, which also inflation and the possibility of generating a positive cosmological constant implies that was hard to explain previously in string theory. In their model, Brane and flows are introduced ( generalizations of magnetic fields) in the six-dimensional Calabi -Yau spaces of string theory background, which stabilize their topology. Their approach solved the problem of stabilization of the moduli ( parameters that parameterize the Calabi -Yau spaces ) and thus another open problem of string theory. 2002 Linde and Kallosch discussed the possibility that our universe is collapsing already in another 13 billion years since the vacuum energy is negative.
Renata Kallosch is married to Andrei Linde cosmologists, with whom she has two sons. Linde is also a professor at Stanford University and a native Russian.
