Gravitational Waves and New Physics - Peter Graham

Explore the frontiers of gravitational wave detection and its implications for new physics in this 47-minute conference talk from the Kavli Institute for Theoretical Physics. Delve into novel experimental approaches for testing fundamental physics, including atomic clocks, pulsar timing, and asteroid observations. Examine the challenges and opportunities in detecting gravitational waves across various frequency ranges, from table-top experiments to kilometer-scale setups. Gain insights into the interplay between experimental techniques and theoretical interpretations in the search for dark matter, axions, and violations of fundamental symmetries. Analyze plots illustrating solar fluctuations, asteroid noise, and gravitational gradient effects. Discuss the potential of LISA-style detectors and the engineering challenges involved in pushing the boundaries of gravitational wave astronomy. Consider the role of moons and asteroids around pulsars in enhancing our understanding of gravitational phenomena. Engage with questions and discussions on relative acceleration and near-field noise in gravitational wave detection.
