Seminars

During the semester we have a high energy seminar and a lunch seminar. In addition to these two seminars we participate in a joint theoretical high energy theory seminar in Newe Shalom. The joint seminar takes place on Tuesdays from 10:30 until 13:30 and includes two talks and lunch. This seminar is attended by the high energy groups of all the Israeli institutions and usually attracts a crowd of roughly twenty participants.

Title: From Scattering Amplitudes to Gravitational Waves Abstract: The remarkable detection of gravitational waves by the LIGO/Virgo collaboration has opened a new window into the cosmos. In this colloquium we explain how particle theorists can help out with high-precision calculations of effective Hamiltonians for predicting gravitational-wave emission from compact astrophysical objects. We explain reamarkable adavances in our ability to compute scattering amplitudes in quantum gravity based on ideas such as the duality between color and kinematics, double-copy relations and generalized unitarity. We then show how these ideas can be harnessed using modern ideas in effective field theory to obtain new and difficult to obtain general relativity corrections to the problem of black hole or neutron star inspirals.

Title : Chern-Simons-Matter Duality and Large-N Phase Diagram Abstract : Pure Chern-Simons (CS) theory looks quite boring at a first glance. However, the theory becomes highly interesting and rich dynamics come out of it once we couple it to dynamical matter fields. It is quite remarkable that the large-N limit of this matter CS theory is exactly solvable. This led to the understanding of the fact that CS gauged fundamental regular (free) fermion theories and CS gauged fundamental critical (Wilson-Fisher) boson theories are not different but secretly the same theory, related by the level-rank duality. In this talk, I will show the extension of this duality when the boson field gets condensed triggering the Higgs mechanism. In the next step, extending this duality to the regular boson/critical fermion case, we will compute the exact quantum effective potential of the regular boson theory and explore the large-N phase diagram of this theory.
