Bound states and glueballs in three-dimensional Ising systems
M. Caselle, M. Hasenbusch, P. Provero +1
We study the spectrum of massive excitations in three-dimensional models belonging to the Ising universality class. By solving the Bethe-Salpeter equation for 3D theory in th…
Bound states in the three dimensional phi^4 model
M. Caselle, M. Hasenbusch, P. Provero +1
We discuss the spectrum of the three dimensional phi^4 theory in the broken symmetry phase. In this phase the effective potential between the elementary quanta of the model is attr…
Matrix strings from generalized Yang-Mills theory on arbitrary Riemann surfaces
M. Billo', A D'Adda, P. Provero
We quantize pure 2d Yang-Mills theory on an arbitrary Riemann surface in the gauge where the field strength is diagonal. Twisted sectors originate, as in Matrix string theory, from…
On the phase diagram of the discrete spin models
Patrick Dorey, Paolo Provero, Roberto Tateo +1
We point out some problems with the previously-proposed phase diagram of the spin models. Consideration of the diagram near to the decoupling surface using both exact and app…
The 2D effective field theory of interfaces derived from 3D field theory
Paolo Provero, Stefano Vinti
The one--loop determinant computed around the kink solution in the 3D theory, in cylindrical geometry, allows one to obtain the partition function of the interface separating…
Chiral Current Algebras in Three--Dimensional Bf--Theory with Boundary
Nicola Maggiore, Paolo Provero
We consider the three--dimensional BF--model with planar boundary in the axial gauge. We find two--dimensional conserved chiral currents living on the boundary and satisfying Kac--…
