ITMP Seminar "Classical solutions and semiclassical expansion of non-relativistic strings in AdS5xS5"

ITMP Seminar
15 декабря 2021

Dear Colleagues,

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Dec 15, at 17:00 (Moscow time). It will take place in ITMP, in person, room Г-725. It will be also possible to participate online via zoom


Speaker: Dr. Andrea Fontanella, ITMP

Title: Classical solutions and semiclassical expansion of non-relativistic strings in AdS5xS5

Abstract:  The S-matrix of a theory is a key object to compute, since it encodes many physical properties of it. In this talk we present some recent work which aims to pave the ground towards an S-matrix computation for non-relativistic strings in AdS5xS5. 

After introducing some key features of the non-relativistic theory, we shall first address the question of how classical string solutions look like in this theory. We shall point out that every solution has a common feature, due to solving the equations of motion for the Lagrange multiplier fields. Some string solutions with closed and twisted boundary conditions will be presented, which represent the non-relativistic (and twisted) analogue of the BMN and GKP solutions for the relativistic theory. The second part of the talk focusses on the perturbative expansion in large string tension of the action around the twisted BMN-like solution. To perform this expansion we shall fix light-cone gauge and also additionally expand in large AdS radius.


If you want to join the seminar please register here before 16:00, December 15 here.
