We are a dynamic research group in the Department of Mathematics. Our aim is to develop mathematical
methods for application to problems in physics, in particular quantum mechanics and quantum chemistry and to prove mathematical
theorems expressing the properties of the quantum system. To this end, we use a wide variety of mathematical theories and methods to tackle these
problems: linear and nonlinear analysis, functional analysis, ordinary and partial differential equations, calculus of variations, operator theory,
spectral and scattering theory etc.
Currently, we are mainly focusing on two different research topics: (1) Electronic structure models (Nonlinear PDEs); (2) Resonances (Spectral and scattering properties of differential operators). Please see Research for more information.
We are located at University of Sussex, the birthplace of the study of Applied Partial Differential Equations in the United Kingdom.
We exchange ideas and work with our neighbors from Chemistry, in particular, Theoretical and Computational Chemistry, as well as with the colleagues in the Atomic, Molecular and Optical Physics group in the Department of Physics.
We are looking for passionate new PhD students, Postdocs, and Master students to join the team (more info) !
