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…
Unitarity violation at the Wilson-Fisher fixed point in 4-epsilon dimensions
Matthijs Hogervorst, Slava Rychkov, Balt C. van Rees
We consider the continuation of free and interacting scalar field theory to non-integer spacetime dimension d. We find that the correlation functions in these theories are necessar…
Remarks on the Convergence Properties of the Conformal Block Expansion
Slava Rychkov, Pierre Yvernay
We show how to refine conformal block expansion convergence estimates from hep-th/1208.6449. In doing so we find a novel explicit formula for the 3d conformal blocks on the real ax…
Conformal Invariance in the Long-Range Ising Model
Miguel F. Paulos, Slava Rychkov, Balt C. van Rees +1
We consider the question of conformal invariance of the long-range Ising model at the critical point. The continuum description is given in terms of a nonlocal field theory, and th…
The Epsilon-Expansion from Conformal Field Theory
Slava Rychkov, Zhong Ming Tan
Conformal multiplets of and recombine at the Wilson-Fisher fixed point, as a consequence of the equations of motion. Using this fact and other constraints from conformal…
