Job announcements relevant to people interested in electronic structure calculations…
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.

Photonastic materials convert light energy into mechanical energy and are the subject of pre-determined and repeatable deformations in response to light stimuli. This phenomenon is usually associated with plants and flowers, whose petals open in the daylight and close in the evening in response to a light stimulus.
Bio-inspired photoactuator devices based on crystals, liquid crystals, metal-organic framework, or polymers were recently proposed. In this project, we are interested in bio-inspired polymeric photoactuator devices which can have applications in microfluidics, biomedics, soft robotics and motors. The keystone of these systems is the insertion of photoactive molecule within polymer films. Our purpose is to identify the key parameters at the molecular and supramolecular scales involved in the mechanical response of a photoresponsive polymeric thin film. The challenge is to rationalize the multiscale mechanisms underlying these phenomena, namely the ultrafast photochromic reactions at the molecular level, the momentum transfer to the surrounding matrix, and after a cascade of processes, the long-term polymer relaxation which yields the macroscopic experimental deformation.
The candidate should have a PhD in Computational Chemistry and a good experience in the application of theoretical methods for photochemical processes. The postdoctoral fellow will mainly use Time-Dependent DFT (TD-DFT) and Molecular Dynamics simulations. Experience in the Force Field parametrizations would be highly appreciated, and programming skills are expected.
