Constructing the Infrared Conformal Generators on the Fuzzy Sphere
Giulia Fardelli, A. Liam Fitzpatrick, Emanuel Katz
We investigate the conformal algebra on the fuzzy sphere, and in particular the generators of translations and special conformal transformations which are emergent symmetries in th…
Toolkit for General 2d Scalar Potential in LCT
A. Liam Fitzpatrick, Emanuel Katz, Yuan Xin
We present efficient algorithms for obtaining the Hamiltonian in Lightcone Conformal Truncation (LCT) for a 2d scalar field with a generic potential. We apply this method to the si…
Large Momentum EFT and Lightcone Quantization
Hongbin Chen, A. Liam Fitzpatrick, Emanuel Katz +1
We develop methods for computing the effective action at infinite momentum for QFTs at finite volume which do not rely on the theory having a Lagrangian description. We do t…
Lightcone Hamiltonian for Ising Field Theory I: T < T_c
A. Liam Fitzpatrick, Emanuel Katz, Yuan Xin
We study 2d Ising Field Theory (IFT) in the low-temperature phase in lightcone quantization, and show that integrating out zero modes generates a very compact form for the effectiv…
