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 ``Journées Cartes'' are regular meetings between researchers from different fields (mathematics, computer science and theoretical physics) working on a same subject : combinatorial maps, models of discrete random surfaces appearing notably in the context of two-dimensional quantum gravity. The next meeting will be held at IPhT on June 20 and 21, 2013. Please feel welcome to listen to our nine young speakers ! |

X-ray tomography is a widely used imaging technique that allows one to produce internal images in materials science or medical applications. An X-ray beam is transmitted through the sample and the projection is recorded on a detector at different angles. The most widely used reconstruction algorithm of the original image from these measurements provides satisfying results only for a large number of such projections. In order to reduce the acquisition time or the total dose absorbed by the patient, tomography users need other reconstruction algorithms that incorporate known properties of the original image. In particular, images with a discrete set of absorption values and few interfaces are frequently encountered in materials science. Inspired by results from statistical physics of the Ising model, Lenka Zdeborova and her colleagues [1] have proposed a novel message-passing algorithm for discrete tomography. The algorithm works on two levels: it is iteratively sending probabilistic messages between the different light rays and different set of messages within each light ray in order to satisfy the observed values of measurements. The resulting algorithm is fast, and entirely distributed. The authors showed that for binary ... |
