17. Exploring effective descriptions of gauge fields and strings : A Lagrangian approach with insights from color-kinematics duality
Sammanfattning : The concept of a color-kinematics duality is an important driving force in advancing the modern understanding of scattering amplitudes, in both field theory and string theory. Yet, open questions remain that motivate the need for a deeper understanding of the duality. LÄS MER
18. Inverse scattering and distribution of resonances on the real line
Sammanfattning : We study aspects of scattering theory for the Schrödinger operator on the real line. In the first part of the thesis we consider potentials supported by a half-line, and we are interested in the inverse problem of reconstruction of the potential from the knowledge of values of the reflection coefficient at equidistributed points on the positive imaginary axis.

19. Transport theory and finite element methods for mesoscopic superconducting devices
Sammanfattning : At low temperatures, electrons in a superconductor exhibit pairing correlations that result in a macroscopic, phase-coherent ground state. This leads to peculiar electromagnetic properties such as the flow of dissipationless charge currents and expelling of external magnetic fields. LÄS MER
20. Scattering Amplitudes in Supersymmetric Quantum Chromodynamics and Gravity
Sammanfattning : Quantum field theory is a theoretical framework for the description of nature in terms of fundamental particles, fields and their interactions. In the quantum regime, elementary scattering processes are observables in many experiments and studied in theoretical physics. LÄS MER
