Conformal Truncation of Chern-Simons Theory at Large
Luca V. Delacrétaz, A. Liam Fitzpatrick, Emanuel Katz +1
We set up and analyze the lightcone Hamiltonian for an abelian Chern-Simons field coupled to fermions in the limit of large using conformal truncation, i.e. with a trun…
Lightcone Effective Hamiltonians and RG Flows
A. Liam Fitzpatrick, Jared Kaplan, Emanuel Katz +2
We present a prescription for an effective lightcone (LC) Hamiltonian that includes the effects of zero modes, focusing on the case of Conformal Field Theories (CFTs) deformed by r…
NLO Renormalization in the Hamiltonian Truncation
Joan Elias-Miro, Slava Rychkov, Lorenzo G. Vitale
Hamiltonian Truncation (a.k.a. Truncated Spectrum Approach) is a numerical technique for solving strongly coupled QFTs, in which the full Hilbert space is truncated to a finite-dim…
High-Precision Calculations in Strongly Coupled Quantum Field Theory with Next-to-Leading-Order Renormalized Hamiltonian Truncation
Joan Elias-Miro, Slava Rychkov, Lorenzo G. Vitale
Hamiltonian Truncation (a.k.a. Truncated Spectrum Approach) is an efficient numerical technique to solve strongly coupled QFTs in d=2 spacetime dimensions. Further theoretical deve…
Constraints on Perturbative RG Flows in Six Dimensions
Andreas Stergiou, David Stone, Lorenzo G. Vitale
When conformal field theories (CFTs) are perturbed by marginally relevant deformations, renormalization group (RG) flows ensue that can be studied with perturbative methods, at lea…
Hamiltonian Truncation Study of the Phi^4 Theory in Two Dimensions II. The Z_2-Broken Phase and the Chang Duality
Slava Rychkov, Lorenzo G. Vitale
The Fock-space Hamiltonian truncation method is developed further, paying particular attention to the treatment of the scalar field zero mode. This is applied to the two-dimensiona…
Hamiltonian Truncation Study of the Phi^4 Theory in Two Dimensions
Slava Rychkov, Lorenzo G. Vitale
We defend the Fock-space Hamiltonian truncation method, which allows to calculate numerically the spectrum of strongly coupled quantum field theories, by putting them in a finite v…
The local Callan-Symanzik equation: structure and applications
Florent Baume, Boaz Keren-Zur, Riccardo Rattazzi +1
The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions…
A naturally light dilaton
Francesco Coradeschi, Paolo Lodone, Duccio Pappadopulo +2
Goldstone's theorem does not apply straightforwardly to the case of spontaneously broken scale invariance. We elucidate under what conditions a light scalar degree of freedom, iden…
