Chiral Limit of 2d QCD Revisited with Lightcone Conformal Truncation
Nikhil Anand, A. Liam Fitzpatrick, Emanuel Katz +1
We study the chiral limit of 2d QCD with a single quark flavor at finite using LCT. By modifying the LCT basis according to the quark mass in a manner motivated by 't Hooft's…
Nonperturbative dynamics of (2+1)d -theory from Hamiltonian truncation
Nikhil Anand, Emanuel Katz, Zuhair U. Khandker +1
We use Lightcone Conformal Truncation (LCT) -- a version of Hamiltonian truncation -- to study the nonperturbative, real-time dynamics of -theory in 2+1 dimensions. This theor…
Introduction to Lightcone Conformal Truncation: QFT Dynamics from CFT Data
Nikhil Anand, A. Liam Fitzpatrick, Emanuel Katz +3
We both review and augment the lightcone conformal truncation (LCT) method. LCT is a Hamiltonian truncation method for calculating dynamical quantities in QFT in infinite volume. T…
Momentum space CFT correlators for Hamiltonian truncation
Nikhil Anand, Zuhair U. Khandker, Matthew T. Walters
We consider Lorentzian CFT Wightman functions in momentum space. In particular, we derive a set of reference formulas for computing two- and three-point functions, restricting our…
An Exact Operator That Knows Its Location
Nikhil Anand, Hongbin Chen, A. Liam Fitzpatrick +2
We use conformal symmetry to define an AdS proto-field as an exact linear combination of Virasoro descendants of a CFT primary operator . We find that both…
RG Flow from Theory to the 2D Ising Model
Nikhil Anand, Vincent X. Genest, Emanuel Katz +2
We study 1+1 dimensional theory using the recently proposed method of conformal truncation. Starting in the UV CFT of free field theory, we construct a complete basis of stat…
The Goldstone Equivalence Theorem and AdS/CFT
Nikhil Anand, Sean Cantrell
The Goldstone equivalence theorem allows one to relate scattering amplitudes of massive gauge fields to those of scalar fields in the limit of large scattering energies. We general…
