Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.
Designing quantum materials with quantum light: ... (No replies)
Back to Job listings...
Abstract:
Cavity quantum materials [1] are a new research field at the boundary between quantum optics and nonequilibrium quantum materials science. Ideas include the control over superconductivity [2] via the formation of hybrid light-matter excitations (polaritons). In this project the PhD student
will learn basic concepts of quantum optics as well as condensed matter theory, and will apply them to a hybrid boson-fermion system with a plasmonic resonance coupled to an electronic excitation. This will be applied to investigate the possibility of inducing long-lived superconducting
states above the equilibrium critical temperature in organic molecular crystals (e.g., K3C60 [3]).
Prerequisites: knowledge of condensed-matter theory and basic many-body
methods (ideally many-body perturbation theory). Elementary programming skills in a language of your choice (C/C++, Python, Julia, Fortran, …).
