Physical States at the Tachyonic Vacuum of Open String Field Theory
Stefano Giusto, Camillo Imbimbo
We illustrate a method for computing the number of physical states of open string theory at the stable tachyonic vacuum in level truncation approximation. The method is based on th…
On the magnetic perturbation of the Ising model on the sphere
P. Grinza, N. Magnoli
In this letter we will extend the analysis given by Al. Zamolodchikov for the scaling Yang-Lee model on the sphere to the Ising model in a magnetic field. A numerical study of the…
A new class of short distance universal amplitude ratios
M. Caselle, P. Grinza, R. Guida +1
We propose a new class of universal amplitude ratios which involve the first terms of the short distance expansion of the correlators of a statistical model in the vicinity of a cr…
The Renormalization of Non-Commutative Field Theories in the Limit of Large Non-Commutativity
C. Becchi, S. Giusto, C. Imbimbo
We show that renormalized non-commutative scalar field theories do not reduce to their planar sector in the limit of large non-commutativity. This follows from the fact that the RG…
