[PAR] [TLE] Joseph Polchinski [SEP] Joseph Polchinski (born May 16, 1954) is an American theoretical physicist and string theorist. [PAR] [TLE] D-brane [SEP] In string theory, D-branes are a class of extended objects upon which open strings can end with Dirichlet boundary conditions, after which they are named.  D-branes were discovered by Dai, Leigh and Polchinski, and independently by Hořava in 1989.  In 1995, Polchinski identified D-branes with black p-brane solutions of supergravity, a discovery that triggered the Second Superstring Revolution and led to both holographic and M-theory dualities.
