ITMP Seminar "The O(N) vector model at large charge: EFT, large N and resurgence"

ITMP Seminar
25 January 2021

Dear Colleagues,

Our seminar is back after Christmas holidays!

We are pleased to announce that the next ITMP seminar will be held on Wednesday, Jan 27, at 18:00 (Moscow time). The seminar will be arranged via Zoom.

Speaker: Dr. Domenico Orlando, INFN Turin,  University of Bern

Title: The O(N) vector model at large charge: EFT, large N and resurgence

Abstract: I will discuss the IR fixed point of the O(N) vector model in 3 dimensions (Wilson-Fisher point) in the framework of the large charge expansion. First I will construct an EFT valid for any N, then verify the prediction of the model in the double scaling limit of large N, large charge and finally discuss the use of resurgence to extend the validity of the EFT to sectors of small charge.

 

If you want to join the seminar please register here before 15:00, January 27.
