Examining mean-field approximations and Bogoliubov-de Gennes (BdG) equations for topological quantum computing - some considerations on the conceptual basis of Majorana zero modes in p+ip superconductors
… solutions to BdG equations. In this framework, particle number conservation is broken and non-interacting fermion Hamiltonian is used to describe physics of interest. We argue that these features in the current framework may make it insufficient for studying topological properties of MZM …

Improving the Dispersive Optical Model toward a Dispersive Self-energy Method
… state properties, such as the charge density, particle number, and the energy per particle. Comparison of these quantities with data suggests additional ways in which the dispersive optical model can be improved. For example, a better treatment of short-range correlations is needed, and …

Density Fluctuations and Phase Behaviour in Non-Equilibrium Systems
… by coarse-graining the microscopic rules of particle motion, or top-down, by imposing conservation laws and symmetries. This thesis addresses two types of phase behaviour, each described by dynamical field theories developed via one of the two approaches. The first concerns phase transitions …
