Field theory of Ising percolating clusters
Gesualdo Delfino
The clusters of up spins of a two-dimensional Ising ferromagnet undergo a second order percolative transition at temperatures above the Curie point. We show that in the scaling lim…
On the space of quantum fields in massive two-dimensional theories
Gesualdo Delfino
For a large class of integrable quantum field theories we show that the S-matrix determines a space of fields which decomposes into subspaces labeled, besides the charge and spin i…
Isomorphism of critical and off-critical operator spaces in two-dimensional quantum field theory
G. Delfino, G. Niccoli
For the simplest quantum field theory originating from a non-trivial fixed point of the renormalization group, the Lee-Yang model, we show that the operator space determined by the…
Confinement in the q-state Potts field theory
Gesualdo Delfino, Paolo Grinza
The q-state Potts field theory describes the universality class associated to the spontaneous breaking of the permutation symmetry of q colors. In two dimensions it is defined up t…
Particle decay in Ising field theory with magnetic field
Gesualdo Delfino
The scaling limit of the two-dimensional Ising model in the plane of temperature and magnetic field defines a field theory which provides the simplest illustration of non-trivial p…
The composite operator T\bar{T} in sinh-Gordon and a series of massive minimal models
Gesualdo Delfino, Giuliano Niccoli
The composite operator T\bar{T}, obtained from the components of the energy-momentum tensor, enjoys a quite general characterization in two-dimensional quantum field theory also aw…
