Pearle Gives Course, Publishes Paper on CSL
Professor of Physics Emeritus Philip Pearle presented a mini-course on his Continuous Spontaneous Localization (CSL) theory of wave function collapse Sept. 30 – Oct. 4 at the National Autonomous University of Mexico (UNAM) in Mexico City.
He was invited by UNAM Professor Daniel Sudarsky. Pearle, along with Sudarsky and graduate student Pedro Cañate, recently published a paper, “Continuous spontaneous localization wave function collapse model as a mechanism for the emergence of cosmological asymmetries in inflation,” in Physical Review D.
In the paper, the authors addressed the problem that the standard quantum theory treatment of the beginning of the universe by the inflationary mechanism does not end with a particular universe such as the one we live in, but only gives a “superposition” of possible universes. They showed how the CSL theory can select a particular universe, consistent with the microwave radiation we observe bathing the universe from its earliest times.
