Jeffrey Barrett Much of Professor Barrett's work has focused on attempts to resolve the quantum measurement problem in non-relativistic quantum mechanics and in quantum field theory. His most recent work in this area has concerned Hugh Everett's interpretation of quantum mechanics. He also has research interests in the proper metaphysics and epistemology of physics.
John Manchak Professor Manchak works on the foundations of general relativity, with a focus on issues concerning the global topological and causal structure of spacetime. Some of his recent work has concerned time travel and spacetime singularities.
James Weatherall Professor Weatherall works primarily on the mathematical and conceptual foundations of classical field theories, including general relativity, Newton-Cartan theory, and (classical) Yang-Mills theory, and on quantum field theory. Some topics of special recent interest have included the role of geometry and symmetry in classical field theories and the status of various central principles of these theories, such as the "geodesic principle" of general relativity.
Penelope Maddy also shares some research interests with the members of this group, particularly in the question of how mathematics works in application to the world.
Current and recent students in this group include Sarita Rosenstock (Yang-Mills theory, theoretical structure and equivalence), Marian Gilton (charge in Yang-Mills theory), Chris Mitsch (the role of axiomatization in physics and philosophy), Benjamin Feintzeig (quantum mechanics, quantum field theory, Yang-Mills theory), and Sam Fletcher (general relativity, quantum gravity). Affiliated Faculty include Donald Saari and Daniel Whiteson. These faculty are among those available for course work and consultation for students pursuing the Physics Emphasis.
The philosophy of physics faculty maintain close research ties with Charlotte Werndl (Salzburg) and her research group through the Salzburg Exchange Program; in addition Professor Weatherall has an ongoing collaboration with Professor Chris Smeenk of the University of Western Ontario on the Philosophy of Cosmology, including regular joint group meetings. The Southern California Philosophy of Physics Group -- consisting of faculty, post-docs, and graduate students from colleges and universities throughout Southern California, including UCSD, UCLA, USC, Occidental, CSU LA, and Chapman -- meets two to three times per quarter at UC Irvine.
