[Drand] Scientific Fika – Friday November 11th 16:00 Room Mega – Nadia: ‘How to get rid of inifity’

[Nikki Arendse]

Dear Juniors, this is a reminder of the Scientific Fika today at 16:00 in the Nordita Mega room. Nadia Flodgren will talk about "Renormalization in perturbative QFT - How to get rid of infinity" and we will have delicious Swedish pastries.

Address: AlbaNova University Center, Hannes Alfvéns väg 12 (6th floor)

We hope to see you there!
Nadia, Guilherme and Nikki

Dear Juniors,

It is my pleasure to announce this week's Scientific Fika. Join us on Friday the 11th of November at 16:00 for a great talk by Nadia and delicious Swedish pastries.

Nadia Flodgren

Renormalization in perturbative
QFT - How to get rid of infinity


Renormalization is a collection of techniques used to study a system at different length scales and it can seem quite complicated. It is very important in both quantum field theory and condensed matter, for example in the study of the standard model. In this talk I will focus on renormalization as it is used in perturbative quantum field theory, where it is used to get rid of inconvenient infinities, and explain how it is performed by using a simple mathematical example (no complicated QFT equations) and the very basics of Feynman diagrams.

Place: NORDITA Floor 6 - Room Mega (in-person only).
Address: AlbaNova University Center, Hannes Alfvéns väg 12
Please put this date in your calendar and come to discuss interesting science.

We're looking forward to seeing you!
Nadia, Guilherme and Nikki
