Abhay Vasant Ashtekar (born
5 July 1949) is an Indian theoretical physicist. He is the Eberly Professor of
Physics and the Director of the Institute for Gravitational Physics and
Geometry at Pennsylvania State University. As the creator
of Ashtekar
variables, he is one of the founders of loop
quantum gravity and its subfield loop quantum cosmology.[2] He has also written a number of descriptions of
loop quantum gravity that are accessible to non-physicists. In 1999, Ashtekar
and his colleagues were able to calculate the entropy for
a black hole, matching
a legendary 1974 prediction by Hawking.[3] Oxford mathematical physicist Roger Penrose has
described Ashtekar's approach to quantum gravity as
"The most important of all the attempts at 'quantizing' general
relativity."[4] Ashtekar was elected as Member to National
Academy of Sciences in May 2016.[5]
BiographY
Abhay Ashtekar grew up in several cities, including Mumbai, in the state
of Maharashtra, India. After completing his undergraduate
education in India, Ashtekar enrolled in the graduate program for gravitation at
the University of Texas at Austin.[1] He went on to complete his Ph.D. at the University of Chicago under the supervision
of Robert
Geroch in 1978 and held several appointments at Oxford, Paris, Syracuse before
settling at Penn
State.[6]
