Petr Hořava

Petr Hořava is a Czech string theorist. He is well-known for his articles written with Edward Witten about the Horava-Witten domain walls in M-theory. These articles demonstrated that the ten-dimensional Heterotic $E\_8\; imes\; E\_8$ string theory could be produced from 11-dimensional M-theory by making one of the dimensions have edges (the domain walls). This discovery provided crucial support for the conjecture that all string theories could arise as various limits of a single higher-dimensional theory. Horava is less well known for his discovery of D-branes, usually attributed to Dai, Leigh and Polchinski, who discovered them independently, also in 1989. He is currently a professor of physics at The University of California at Berkeley, where he frequently teaches courses on quantum field theory and string theory. Hořava is also a member of the theory group at Lawrence Berkeley National Laboratory.
