Semiclassical Methods in 2D QFT: Spectra and Finite-Size Effects
Valentina Riva
We review some recent results obtained in the analysis of two-dimensional quantum field theories by means of semiclassical techniques, which generalize methods introduced during th…
Holomorphic Parafermions in the Potts model and SLE
V. Riva, John Cardy
We analyse parafermionic operators in the Q-state Potts model from three different perspectives. First, we explicitly construct lattice holomorphic observables in the Fortuin-Kaste…
Identification of the stress-energy tensor through conformal restriction in SLE and related processes
B. Doyon, V. Riva, J. Cardy
We derive the Ward identities of Conformal Field Theory (CFT) within the framework of Schramm-Loewner Evolution (SLE) and some related processes. This result, inspired by the obser…
Kink scaling functions in 2D non--integrable quantum field theories
G. Mussardo, V. Riva, G. Sotkov +1
We determine the semiclassical energy levels for the ϕ^4 field theory in the broken symmetry phase on a 2D cylindrical geometry with antiperiodic boundary conditions by quantizing…
Scale and conformal invariance in field theory: a physical counterexample
V. Riva, J. Cardy
In this note, we illustrate how the two-dimensional theory of elasticity provides a physical example of field theory displaying scale but not conformal invariance.
Semiclassical methods in 2D QFT: spectra and finite-size effects
Valentina Riva
In this thesis, we describe some recent results obtained in the analysis of two-dimensional quantum field theories by means of semiclassical techniques. These achievements represen…
