Abstract: LIGO and Virgo have observed over 70 gravitational-wave sources to date, including mergers between black holes, neutron stars, and mixed neutron star- black holes.
Abstract: The history of perturbative calculations in de Sitter space is littered with confusing and often contradictory results.
Abstract: I will introduce the basic principles of searching for Dark Matter with cosmic rays, and then summarize the status of such searches, focusing on some recent developments…
Abstract: Several puzzles and issues in quantum gravity are related to the question of what type of high-energy information is actually available to low-energy observers.
Abstract: A quantum system is said to be many-body localized (MBL) if it remains close to its initial state, i.e., it fails to thermalize.
