Abhay Vasant Ashtekar (born 5 July 1949) is an Indian theoretical physicist who created Ashtekar variables and is one of the founders of loop quantum gravity and its subfield loop quantum cosmology.[2] Ashtekar has also written a number of descriptions of loop quantum gravity that are accessible to non-physicists.
He is an Evan Pugh Professor Emeritus of Physics and former Director of the Institute for Gravitational Physics and Geometry (now Institute for Gravitation and the Cosmos)[3] and Center for Fundamental Theory[4] at Pennsylvania State University.
In 1999, Ashtekar and his colleagues were able to calculate the entropy for a black hole, matching a 1974 prediction by Stephen Hawking.[5] Oxford mathematical physicist Roger Penrose has described Ashtekar's approach to quantum gravity as "The most important of all
