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…

Boundary effects in two-dimensional critical and off-critical systems
Valentina Riva
Critical systems are described by conformal field theories, whose dynamics can be exactly solved in two dimensions. In the presence of a boundary, with the so-called method of imag…
