The research performed at the IPhT aims at better understanding the laws which govern our universe and its organisation. It encompasses most of the great subjects of modern theoretical physics:
The IPhT comprises about fifty permanent physicists (2/3 CEA, 1/3 CNRS), about thirty PhD students and postdocs, assisted by a support staff of about ten people. The IPhT also hosts permanently many short term visitors.
The conference "de Sitter and microstate lansdscapes in string theory" took place at IPhT from June 16 to 19, 2015. This workshop gathered 70 participants from around the world to discuss recent advances in understanding the landscapes of de Sitter spaces in string theory on one hand, and of black hole microstate geometries on the other. Both landscapes have experienced quite intense recent remodeling: on the black hole side this was driven by “fuzzball/firewall” informationtheorybased arguments that black hole solutions are only thermodynamic approximations that stop describing the physics at the scale of the horizon, where they should be replaced by horizonless geometries dual to the black hole microstates, and on the cosmology side by the realization that antibranes, which are one of the key ingredients needed to obtain a landscape of de Sitter vacua, may give rise to instabilities.

Romain Vasseur, former graduate student at IPhT, has been awarded a 2015 PhD prize from the "Triangle de la Physique", in the category "Theory". Romain's PhD thesis, codirected by Hubert Saleur (IPhT) and Jesper Jacobsen (LPTENS), is dealing with nonunitary Conformal Field Theories and various applications in condensed matter physics and geometrical models of statistical mechanics. Romain is now postdoc at UC Berkeley. Congratulations Romain!

Hubert Saleur, permanent physicist at IPhT, has just been awarded a prestigious Advanced Grant from the European Research Council. This grant will allow him to develop, during the 5 next years, his research project on the "plateau transition" in the Quantum Hall Effect, a famous unsolved problem in condensed matter physics. In this direction, he also aims at studying and classifying Nonunitary Conformal Field Theories.
Congratulations Hubert!
