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…
Bulk Matter and the Boundary Quantum Null Energy Condition
Zuhair U. Khandker, Sandipan Kundu, Daliang Li
We investigate the quantum null energy condition (QNEC) in holographic CFTs, focusing on half-spaces and particular classes of states. We present direct, and in certain cases nonpe…
A General Proof of the Quantum Null Energy Condition
Srivatsan Balakrishnan, Thomas Faulkner, Zuhair U. Khandker +1
We prove a conjectured lower bound on in any state of a relativistic QFT dubbed the Quantum Null Energy Condition (QNEC). The bound is given by the…
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…
