The Van't Hoff Institute for Molecular Sciences (HIMS) and the Institute of Physics (IoP) of the Faculty of Science invite applications for a four-year research position at the PhD level. There are two PhD positions in the field of Soft Matter available. One is on theoretical/computational research in the Computational Chemistry & Physics group of Prof. P.G. Bolhuis of HIMS, the other is on experimental research in the Soft Matter Group of Prof. Schall of the WZI.
The two positions are part of a joint project 'Activating viscoelastic colloidal architectures'. Structural architectures in living cells, such as the cytoskeleton in muscle or plant tissue, are both viscoelastic and active, i.e. undergo continuous injection of energy, leading to remarkable collective, non-equilibrium properties. Understanding such phenomena remains one of the grand challenges of modern statistical physics. While active fluids (swarms, swimmers) have seen an explosion of interest recently, their solid (elastic) counterparts remain completely unexplored. In this project, we want to combine activity and viscoelastic architecture in synthetic (colloidal) systems to discover the emergent collective behaviour of active viscoelastic architectures, such as locomotion, shape changes and unusual transport properties, all hallmarks of their biological analogues. Building on our breakthroughs in colloidal architecture control, we will self-assemble and activate architected colloidal materials to investigate their non-equilibrium response, active instabilities, and nonlinear shape changes.
The aim of these two PhD positions is to discover general principles of active architectures and living matter, something that cannot be done for their molecular counterparts. By probing these phenomena in experiments at the colloidal scale and in simulations, we will unravel the as-of-yet unexplored physics of active elastic solids and achieve key insights into the statistical mechanics of living systems that in turn can be used for the design of novel active materials.
The experimental and computational research will involve binding 'patchy' colloidal particles with specific symmetry into complex architectures via directly controllable critical Casimir forces. This combination allows exquisite control of the architecture’s local topology and connectivity on the one hand, and bending rigidity and stiffness on the other. The colloidal architectures will be activated by implementation of active particles driving it continuously out of equilibrium. The computational approach involves molecular (Browinan) dynamics simulations together with rare event techniques that should be performed in close connection with the experiments.
We expect you to have:
- a Master's degree in Physcis or Physical Chemistry;
- experience in the following fields: colloidal/nanoparticle synthesis or assembly, Soft Matter, Statistical Mechanics (for the experimental position);
- experience in the following field: computational soft matter, molecular simulation, statistical mechanics, programming (for the computational position).
You should be able to collaborate and adapt in an international team and possess good communication skills in oral and written English.
The appointment will be on a temporary basis for a period of 4 years (initial appointment will be for a period of 18 months and after satisfactory evaluation it can be extended for a total duration of 4 years) and should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching of undergraduates.
Based on a full-time appointment (38 hours per week) the gross monthly salary will range from €2,266 in the first year to €2,897 in the last year. The Collective Labour Agreement for Dutch Universities is applicable. Favourable tax agreements may apply to non-Dutch applicants.
