Properties of scalar partition functions of 2d CFTs

Nathan Benjamin, Cyuan-Han Chang, A. Liam Fitzpatrick +1

We study the spectrum of scalar primary operators in any two-dimensional conformal field theory. We show that the scalars alone obey a nontrivial crossing equation. This extends pr…

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…

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…

Exact Virasoro Blocks from Wilson Lines and Background-Independent Operators

A. Liam Fitzpatrick, Jared Kaplan, Daliang Li +1

Aspects of black hole thermodynamics and information loss can be derived as a consequence of Virasoro symmetry. To bolster the connection between Virasoro conformal blocks and AdS$…

Closure of the Operator Product Expansion in the Non-Unitary Bootstrap

Ilya Esterlis, A. Liam Fitzpatrick, David Ramirez

We use the numerical conformal bootstrap in two dimensions to search for finite, closed sub-algebras of the operator product expansion (OPE), without assuming unitarity. We find th…

Small Black Holes and Near-Extremal CFTs

Nathan Benjamin, Ethan Dyer, A. Liam Fitzpatrick +2

Pure theories of AdS quantum gravity are conjectured to be dual to CFTs with sparse spectra of light primary operators. The sparsest possible spectrum consistent with modular i…

Universal Bounds on Charged States in 2d CFT and 3d Gravity

Nathan Benjamin, Ethan Dyer, A. Liam Fitzpatrick +1

We derive an explicit bound on the dimension of the lightest charged state in two dimensional conformal field theories with a global abelian symmetry. We find that the bound scales…

Anomalous Dimensions of Non-Chiral Operators from AdS/CFT

A. Liam Fitzpatrick, David Shih

Non-chiral operators with positive anomalous dimensions can have interesting applications to supersymmetric model building. Motivated by this, we develop a new method for obtaining…

Effective Conformal Theory and the Flat-Space Limit of AdS

A. Liam Fitzpatrick, Emanuel Katz, David Poland +1

We develop the idea of an effective conformal theory describing the low-lying spectrum of the dilatation operator in a CFT. Such an effective theory is useful when the spectrum con…

Discovering Asymmetric Dark Matter with Anti-Neutrinos

Brian Feldstein, A. Liam Fitzpatrick

We discuss possible signatures of Asymmetric Dark Matter (ADM) through dark matter decays to neutrinos. We specifically focus on scenarios in which the Standard Model (SM) baryon a…
