Open positions

  • Postdoctoral position in metamaterials

    The Adolphe Merkle Institute (AMI) at the University of Fribourg in Switzerland invites applications for a Postdoc position in the Soft Matter Physics group of Prof. Ullrich Steiner.

    The SNSF funded project on “Optical left-handed metamaterials from metallic double-nets” will investigate a new type of double network metamaterial at visible frequencies. The proposed metamaterial carries the promise of broadband longitudinal left-handed propagation with a number of interesting physical consequences such as “black-hole” dipole emission. The purpose of the project is to theoretically study classical light propagation in the proposed metamaterials to spark further research into quantum emission, self-assembly fabrication and nano-photonics experiments in a subsequent project.

    The research will concentrate on metamaterials made of noble metals (gold and silver) at visible frequencies and encompass the following three aspects:

    • Development of a network current based homogenization theory to gain in-depth understanding of the metamaterial bulk normal modes and use them as a solution basis for future research
    • Full wave electro-magnetic numerical mode calculations with COMSOL Multiphysics to obtain precise predictions and compare to the theory
    • Optical simulations of slab-like geometries with COMSOL and Lumerical FDTD Solutions to predict observables for experimental optical characterization

    The project will be closely integrated in the experimental Soft Matter Physics group at the Adolphe Merkle Institute. The applicant will work with Dr. Matthias Saba, and collaborate with the polymer self-assembly team to (a) confine the theoretical investigations to experimentally realistic parameters and (b) guide first steps towards double-net metamaterial fabrication.

    The successful applicant will hold a PhD degree in Physics, Engineering or a related discipline. Research experience in theoretical nano-photonics, metamaterials, photonic crystals or a related field would be advantageous. The applicant should ideally have some experience with semi-analytical and numerical methods to solve (non-linear) eigenproblems and differential equations, in particular Galerkin or boundary element methods, and Green function approaches. Experience with the commercial solvers COMSOL and/or Lumerical is a plus. During the project, there will be the opportunity to collaborate with both our in-house experimental team and international groups, mainly in the UK, USA, and Finland. There will also be the possibility to extend the post and continue research in the direction of quantum photonics and experimental investigations of the proposed double-net metamaterials after the successful project.

    The Adolphe Merkle Institute at the University of Fribourg is a recently established center of competence, focused on research in the field of soft nano-materials, science and technology. With the objective to stimulate innovation, AMI aims to combine fundamental and application-oriented research within an interdisciplinary setting. AMI offers highly competitive working conditions, an outstanding infrastructure and a competitive salary. The contract will be initially for one year, with the option for an extension.

    Please email your application to ami-applications@unifr.ch including your CV, a cover letter, and contact information of (at least) one reference. Review of applications will begin immediately upon receipt of complete application materials. Informal questions can be addressed to Matthias Saba (matthias.saba@unifr.ch).

  • 4 PhD positions in optics

    The Adolphe Merkle Institute (AMI) at the University of Fribourg in Switzerland invites applications for 4 PhD positions in the Soft Matter Physics group of Prof. Ullrich Steiner.

    The goal of the ERC funded project “Photonic Structural Materials with Controlled Disorder” is the discovery how structural color arises from materials with various degrees of disorder. The projects encompass the following four domains:

    • Tomographic analysis of disordered materials occurring in nature (e.g. bird feathers), the discovery of structural correlations in these materials and linking them with their optical properties
    • The analysis of disordered optical gratings occurring in plants and the development of models describing their optical response
    • The manufacture of materials that replicate the properties of the materials described above. This includes the discovery how nature creates these materials
    • The development of numerical and analytic methods to describe and model the propagation of light through disordered media

    The project includes the investigation of these structures with state-of-the-art tomographic methods, synthetic and self-assembly methodologies to create structured materials and both analytic and simulation methods analyzing structural correlations and the light-matter interaction in disordered materials.

    The successful applicant will hold a Master’s degree (or equivalent) in Physics, Materials Science or a related field, preferably with a focus on optics, topology or structure-function interactions. While the projects are mostly experimental, there is also the possibility to carry out a theoretical PhD project on the analytical analysis and numerical simulation of disordered materials and their optical response.  The candidate should wish to pursue independent research involving optical characterization techniques, electron microscopy, analytic theories or optical simulations. Excellent communication skills in English (both written and oral) are an essential requirement. PhD positions at AMI provide the opportunity of close collaborations with other groups at AMI, the Faculty of Sciences, within the National Center of Competence in Research “Bio-inspired Materials”, as well was with the University of Cambridge and several US universities.
