James Hartle

James Burkett Hartle is an American physicist. He has been a professor of physics at the University of California, Santa Barbara since 1966, and he is currently a member of the external faculty of the Santa Fe Institute. Hartle is known for his work in general relativity, astrophysics, and interpretation of quantum mechanics.

In collaboration with Murray Gell-Mann and others, Hartle developed an alternative to the standard Copenhagen interpretation, more general and appropriate to quantum cosmology, based on consistent histories.

With Dieter Brill in 1964, he discovered the "Brill-Hartle geon", an approximate solution realizing Wheeler's suggestion of a hypothetical phenomenon in which a gravitational wave packet is confined to a compact region of spacetime by the gravitational attraction of its own field energy.

Working at the Enrico Fermi Institute at the University of Chicago in 1983, he developed the Hartle-Hawking wavefunction of the Universe in collaboration with Stephen Hawking. This specific solution to the Wheeler-deWitt equation is meant to explain the initial conditions of the Big Bang cosmology.

Hartle is the author of a recent textbook on general relativity.
