Petr Hořava (born 1963 in Prostějov)Profile at Grant Fund Neuron website is a Czech string theorist. He is a professor of physics in the Berkeley Center for Theoretical Physics at the University of California, Berkeley, where he teaches courses on quantum field theory and string theory. Hořava is a member of the theory group at Lawrence Berkeley National Laboratory.
Work Hořava is known for his articles written with Edward Witten about the Hořava–Witten domain walls in M-theory. These articles demonstrated that the ten-dimensional heterotic 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 limits of a single higher-dimensional theory.
Hořava is less well known for his discovery of D-branes, usually attributed to Jin Dai, Robert Leigh and Joseph Polchinski, who discovered them independently, also in 1989.
In 2009, Hořava proposed a theory of gravity that separates space from time at high energy while matching some predictions of general relativity at lower energies.Zeeya Merali, "Splitting Time from Space—New Quantum Theory Topples Einstein's Spacetime", Scientific American (Dec. 2009).
