Postdoctoral Fellow in Theoretical Quantum and Gravitational Physics

Project description

The position will be associated with Dr Magdalena Zych’s research grant focused on quantum aspects of spacetime and their quantum optical analogues, from the Swedish Research Council. Dr Zych is looking for an Postdoctoral Fellow candidate to join her group at the Stockholm University, currently including two Postdoctors and 4 PhD students. The research of the group in general lies at the intersection of quantum theory and general relativity.

In this project specifically we will aim to advance models of quantum fields in non-classical spacetimes described through quantum boundary conditions or non-classical dispersion relations and explore indirect ways such spacetime non-classicality can be revealed through observations on the fields or via quantum systems coupled to fields which reside in the spacetime.

Main responsibilities

The position involves research in collaboration with Dr Zych and PhD or master students in the group. The candide will be furthermore expected to participate and co-organise group activities such as seminars and journal clubs, participate and present at scientific meetings, as well as contribute to organisation of conferences/workshops held locally.

Particular research focus for this position is developing theoretical description of quantum fields with quantum-controlled dispersion relations or boundary conditions, findig mapping between the physics of such fields and the physics of quantum fields in non-classical spacetimes, and developing proposals for accessing signatures of non-classicality eg via measurements on matter interacting with the fields.
