Ashoke Sen at Harvard

Ashoke Sen is an Indian theoretical physicist who works on string theory. Sen received his PhD from State University of New York at Stony Brook. He worked as a research scientist in Fermilab and SLAC. Later he joined TIFR before he finally moved to HRI. He co-discovered S-duality and proposed a successful explanation of open string tachyon condensation. He has also co-written many papers on string field theory. Sen is a winner of the ICTP Prize.

Theoretical physics attempts to understand the world by making a model of reality, used for rationalizing, explaining, predicting physical phenomena through a physical theory. There are three types of theories in physics; mainstream theories, proposed theories and fringe theories. ... Interaction in the subatomic world: world lines of pointlike particles in the Standard Model or a world sheet swept up by closed strings in string theory String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects (strings) rather than the zero-dimensional points (particles... PhD usually refers to the academic title Doctor of Philosophy PhD can also refer to the manga Phantasy Degree This is a disambiguation page — a list of pages that otherwise might share the same title. ... The State University of New York (acronym SUNY; usually pronounced SOO-nee) is a system of public institutions of higher education in New York, United States. ... In theoretical physics, S-duality (also a strong-weak duality) is an equivalence of two quantum field theories, string theories, or M-theory. ... An open string is a one-dimensional fundamental object in string theory that has two end-points, and therefore is topologically equivalent to a line interval. ... In physics, tachyon condensation is a process in which a tachyonic field—usually a scalar field—of a negative squared mass acquires a vacuum expectation value and reaches the minimum of the potential energy. ... String field theory is a proposal to define string theory in such a way that the background independence is respected. ...
