In celebration of the vast and deep scientific achievements of our colleague and Nobel Prize winner Prof. Anthony J. Leggett,  beginning this Fall 2023 our Institute will be known as  The Anthony J. Leggett Institute for Condensed Matter Theory. As part of this occasion we are  proud to announce the  upcoming workshop New Horizons in Condensed Matter Physics, to be held here on November 3-5, 2023, where the renaming of the Institute will become official.

"Modified Gravity" is an event sponsored by the Illinois Center for Advanced Studies of the Universe and the Institute for Condensed Matter Theory, taking place in Urbana, Illinois on May 18 - 20, 2023 in 190 Engineering Sciences Building.

The purpose of this workshop is to bring together various experts in modified gravity from string theorists to cosmologists. GR has been experimentally verified a plethora of times and has passed all the tests so far, although these tests have been conducted at high precision only at what one might consider medium size scales (of the order of our solar system).  Despite this, aside from the very important and deep elusive question of quantization of the theory, there are cosmological (and classical) issues that the theory does not seem to be able to explain, such as the speed of expansion of the universe, dark energy and dark matter.  Therefore, there seems to be a need to modify gravity at very large and at very small scales.
