The three-body problem from Newton to gravitational waves

Title: The three-body problem from Newton to gravitational waves

Speaker: Dr. Alessandro Alberto Trani

Abstract:   

The gravitational few-body problem is one of the oldest conundrums in astronomy and classical mechanics. Yet, its simplest instance, the three-body problem, has no general analytical solution and only a partial statistical solution has been achieved so far. With the birth of gravitational wave astronomy and the rise in exoplanet discoveries, the three-body problem is again becoming central to explaining astrophysical phenomena.

Journal club seminar: A short review of N=2 SUSY Quantum Mechanics

Title:A short review of N=2 SUSY Quantum Mechanics

Abstract: We are going to SUSY Quantum Mechanics. The good review of the subject is a paper by F. Cooper, A. Khare, U. Sukhatme   "Supersymmetry and Quantum Mechanics". Mirian Tsulaia will lead the discussion. 

QG group meeting: Symplectic Reduction in Field Theory

Title: Symplectic Reduction in Field Theory

Speaker: Slava Lysov

Abstract: We will briefly review the symplectic recution in finite dimensional case and generalization to the field theory with possible inclusion of the edge modes. We will apply these ideas to the  BF-model and compare the results with the predictions of algebraic topology.
