Quantum Gravity and Black Holes
Many physicists believe that entanglement is the essence of quantum weirdness — and some now suspect that it may also be the essence of space-time geometry.
Circumventing a no-go theorem established in 1977 by nonlinearly realized supersymmetry, the authors construct for the first time a pure (without additional fields) N=1 supergravity with positive cosmological constant.
Tensor networks provide toy models which explicitly realize many puzzling features of AdS/CFT correspondence, and are sometimes treated as the lossy descriptions of the skeleton (in the AdS scale) of
Simons Collaborations bring together groups of outstanding scientists to address mathematical or theoretical topics of fundamental scientific importance.
A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.
A basic question in black hole horizon physics the leading breakdown of the low-energy description in terms of quantum fields and general relativity (collectively known as effective field theory).
A concept developed for computer science could have a key role in fundamental physics — and point the way to a new understanding of space and time.
