Minimal state representation of homogeneous reaction systems
Dominique Bonvin, Michael Amrhein, Nirav Pravinbhai Bhatt
Minimal state representations are parsimonious models having no redundant states. For homogeneous reaction systems with S species, R independent reactions, p independent inlet streams and one outlet stream, a nonlinear transformation of the numbers of mole ...
2010Universal constraints on conformal operator dimensions
We continue the study of model-independent constraints on the unitary conformal field theories (CFTs) in four dimensions, initiated in [R. Rattazzi, V. S. Rychkov, E. Tonni, and A. Vichi, J. High Energy Phys. 12 (2008) 031]. Our main result is an improved ...
2009Local bulk S-matrix elements and conformal field theory singularities
We give a procedure for deriving certain bulk S-matrix elements from corresponding boundary correlators. These are computed in the plane-wave limit, via an explicit construction of certain boundary sources that give bulk wave packets. A critical role is pl ...
Amer Physical Soc2009Bounding scalar operator dimensions in 4D CFT
Riccardo Rattazzi, Alessandro Vichi
In an arbitrary unitary 4D CFT we consider a scalar operator phi, and the operator phi(2) defined as the lowest dimension scalar which appears in the OPE phi x phi with a nonzero coefficient. Using general considerations of OPE, conformal block decompositi ...
