Local CFTs extremise
Ludo Fraser-Taliente
Many CFTs can be extended to lines of nonlocal CFTs parametrised by the scaling dimension of the fundamental field appearing in the action. is set by the e…
Quantum field theories with many fields
Ludo Fraser-Taliente
The large- quantum field theories provide a window into the regime of strongly-coupled physics. Our principal object of study in this thesis is the large- family of melonic Q…
The of the conformal scalars
Kit Fraser-Taliente, Ludo Fraser-Taliente
We construct the unique primary energy-momentum tensor for the conformal free scalar with scaling dimension as a sum of Gegenbauer polynomials. For integer $…
The sphere free energy of the vector models to order
Ludo Fraser-Taliente
We calculate the large- expansion of the sphere free energy of the O(N) and the Gross-Neveu CFTs to order . Analytic regularization…
Four-point function of the complex Sachdev-Ye-Kitaev model at finite chemical potential
Can Onur Akyuz, Erick Arguello Cruz, Ludo Fraser-Taliente +1
It is known that, for a range of chemical potentials, the infrared behavior of the complex Sachdev-Ye-Kitaev (cSYK) model is governed by a 1D Nearly Conformal Field Theory (NCFT$_{…
-extremization determines certain large- CFTs
Ludo Fraser-Taliente, John Wheater
We show that the conformal data of a range of large- CFTs, the melonic CFTs, are specified by constrained extremization of the universal part of the sphere free energy $F=-\log…
