Lonti: Conformal blocks in two dimensions

Regular Seminar Gerard au:Watts'><span class='hl'>Gerard</span> Watts (KCL)

at:
10:30 KCL
room Online
abstract:

This is the live session included as part of the LonTI lecture on Conformal blocks in two dimensions. Please register at https://lonti.weebly.com/registration.html to receive joining instructions for this live session which will be held via Zoom.Conformal blocks are the building blocks of conformal field theories, the key ingredients of correlation functions and knowledge of these blocks is central to the conformal bootstrap. This lecture covers some general results before quickly specialising to two-dimensions. It discusses the implications of global conformal invariance and then the larger and more constraining Virasoro algebra symmetry. It introduces various methods of calculation including brute force, differential equations, recursion relations and closed formulae - and some aspects of bootstrap techniques.

The effect of level truncation in TCSA

Informal Seminar Gerard au:Watts'><span class='hl'>Gerard</span> Watts (KCL)

at:
15:00 KCL
room 436
abstract:

The truncated conformal space approach is a very useful tool in the numerical study of renormalisation group flows. I will discuss how one can study the effect of truncation in a standard RG manner and its relevance for studying perturbative fixed points.
