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…
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…
Semiclassical Energy Levels of Sine-Gordon Model on a Strip with Dirichlet Boundary Conditions
G. Mussardo, V. Riva, G. Sotkov
We derive analytic expressions of the semiclassical energy levels of Sine-Gordon model in a strip geometry with Dirichlet boundary condition at both edges. They are obtained by ini…
Boundary Quantum Field Theories with Infinite Resonance States
P. Mosconi, G. Mussardo, V. Riva
We extend a recent work by Mussardo and Penati on integrable quantum field theories with a single stable particle and an infinite number of unstable resonance states, including the…
