Non-Markovian wave-function collapse models are Bohmian theories in disguise
Wednesday, 9 March 2022 @ 12PM in 149 Keck Center, or join us on Zoom. Abstract: Spontaneous collapse models models and Bohmian mechanics are two different solutions to the measurement problem plaguing orthodox quantum mechanics. They have a priori nothing in common. At a formal level, collapse models add a non-linear noise term to the
"Implications of action principles for quantum foundations"
Thursday, March 3rd, 2022, 11 AM, Keck Center 149 Join us on Zoom. Abstract: The classical action has been intertwined with quantum theory for over a century, but the connection between the two continues to be unclear. Is the action meaningful in its own right, or just a “trick” for generating dynamical equations of motion?
The Musical Cosmos
Wednesday, December 8th, 7 – 8:30 PM PST Location: Beckman 404 Abstract: In this talk we will explore the improvisational and musical nature of mathematics and physics.
IQS Seminar: Quantum Galaxies
Monday, December 13th, 2021, 12 PM, Keck Center 149 https://chapman.zoom.us/j/96152234419?pwd=YXRvdVhPWnkrU0dWZlBkeG9kSk9EUT09 Abstract: All matter, visible and dark, had to originate from some mysterious event in the early universe-baryogenesis and dark-genesis. This necessary physics goes beyond our standard cosmology and the standard model of particle physics. In this talk, I provide a pedagogical introduction to cosmic inflation,

IQS Seminar: Quantum Computing at the Speed of Light
Location: Room 149 of the Keck Center Time and Date: Wednesday, Nov. 3, at 4pm. https://chapman.zoom.us/j/99926295635?pwd=Vlgwd0wvM1VwV0xQcHNmMHM1UWdvZz09 Meeting ID: 999 2629 5635 Abstract: Physical advantages to building a quantum computer out of optical frequency photons include: they suffer negligible environment decoherence even at room temperature, there is no cross talk, they network easily into arbitrary
IQS Seminar: Quantum Field Theories in Discrete Spacetimes
Professor Todd Brun will be visiting from USC and giving a seminar next Monday, October 25th at 12PM in Room 149 of the Keck Center (the Dean’s Suite Conference Room). The talk will also be live on Zoom: https://chapman.zoom.us/j/95649186660?pwd=QTVzZ1FlSm55NU9SaUFwTmpzUms2UT09 Title: Quantum field theories in discrete spacetimes Abstract: Quantum walks (QWs) are unitary analogues of classical
What's Eating the Universe? And Other Cosmic Questions
Friday, 5 November @ 3PM in Memorial Hall Auditorium In the constellation of Eridanus there lurks a cosmic mystery, as if something has taken a huge bite out of the universe, leaving a supervoid. Could it be an enormous black hole, another universe, or an expanding vacuum bubble, destined to annihilate everything in existence? That

Back from the Future: Retrocausality in the Foundations of Quantum Mechanics
Wednesday October 6, 6pm PDT (California Time) The Institute for Quantum Studies at Chapman University presents an online discussion between Dr. Roderick Sutherland (University of Sydney, Australia) and Dr. Matthew Leifer (Institute for Quantum Studies, Chapman University). Dr. Sutherland is a leading advocate of theories involving retrocausation (backwards-in-time influences) as a resolution for the problems
