I am a theoretical physicist working in Quantum Field Theory (QFT). I specialize on
the study of integrable 1+1-dimensional QFTs and other related theories,
such as statistical models, conformal field theories and integrable quantum spin chains.
Integrable models posses extra symmetries (that is, a large or infinite number of conserved quantities). This
leads to very strong
constraints on the form and value of all their physical quantities. Integrability combined with
the restriction to one space dimension allows for the formulation of theories whose
scattering amplitudes, form factors and correlation functions may be computed
exactly. The systematic computation of these quantities is referred
to as the "Bootstrap Programme" and it has attracted a great deal of attention over the last
four decades.
Much of the work that I have carried out relates to the development of such a programme, that is,
computing scattering matrices, form factors and correlation functions in a
variety of models and investigating
their analytical properties and mathematical structures. A particular class of models
which I have studied in depth are the homogenous sine-Gordon models. I have also been interested
in integrable models with boundaries and defects. The main techniques that I have used in this context are the Thermodynamic Bethe ansatz
and the form factor programme. Much of my work in these areas has been carried out in collaboration
with
Prof. Andreas Fring.
In recent years, I have been appliying some of the techniques above to the development of
a systematic approach to the computation of the entanglement entropy associated to a the ground
state of integrable QFTs and quantum spin chains. This work has been carried out in collaboration
with
Dr Benjamin Doyon
and
Prof. John Cardy and continues
to be pursued in collaboration with Dr Doyon and my PhD student Mr Emanuele Levi.
My past work also includes collaborations with Prof. Jean-Michel Maillet,
Prof. J. Luis Miramontes,
Dr. Carla Figueira de Morisson Faria,
Dr Frank Göhmann, Mr Julian
Dreißig, and Dr Christian Korff.
