Research Assistant position in Berlin bei Weierstraß Institut für Angewandte Analysis und Stochastik

The Weierstrass Institute for Applied Analysis and Stochastics (WIAS) is an institute of the Forschungsverbund Berlin e.V. (FVB). The FVB comprises seven non-university research institutes in Berlin which are funded by the federal and state governments. The research institutes belong to the Leibniz Association.

WIAS invites applications for a

Research Assistant position (f/m/d)

(Ref. 24/19)

in the Research Group

“Laser Dynamics”

(Head: Priv.-Doz. Dr. Uwe Bandelow) starting from 01.10.2024.

This position will be funded for a period up to 24 months by the Leibniz Collaborative Excellence program. The research subject will be a theoretical and numerical study of photonic crystal surface-emitting semiconductor lasers (PCSELs). It will be conducted in close collaboration with physicists and electrical engineers from the Ferdinand Braun Institute (FBH) in Berlin.

The work tasks include:
The researcher will work on the theoretical aspects of the collaborative project “Excellence in Photonic Crystal Surface Emitting Lasers," which aims to develop a new generation of high-power, high-quality semiconductor emitters. The basic theoretical model used for the simulation and analysis of PCSELs is given by a system of PDEs defined in 1 (temporal) and 2 (spatial) dimensions. For more advanced modeling, it will be necessary to consider the selected model components in all three spatial dimensions. It is expected that under the supervision of the experts from WIAS and FBH, the researcher will work on the development of efficient numerical tools suited for solving numerically the dynamical PDE model and the related spectral problem.

We are looking for: Applicants should hold a Ph.D. degree in mathematics, scientific computing, or theoretical physics and have good speaking and writing skills in English. Experience in efficient numerical methods for PDEs and good programming skills in Julia and/or C++ are expected; knowledge of semiconductor device modeling and semiconductor physics would be an advantage.

What we offer:

• WIAS Berlin is a premier research institution known for its strength in mathematical mod-eling, optimization, dynamical systems, and applied mathematics in general.
• Payment according to the collective agreement for the public service (TVöD Bund) including the usual social benefits (30 vacation days in a 5-day week, company pension plan); subsidy for the company ticket for public transport
• Mobile working
• A certified (Audit berufundfamilie) family-friendly work environment.
• Berlin offers endless opportunities to enjoy life outside work. Neither the job nor living in Berlin requires German language (although WIAS offers free German courses). We highly welcome international applications. Scientifically, Berlin offers a rich landscape with numerous opportunities for research, as well as job prospects in academia and industry.

Please direct scientific queries to Dr. M. Radziunas (Mindaugas.Radziunas@wias-berlin.de).

The appointment is initially limited for two years. The salary is according to the German TVöD scale.

The Weierstrass Institute is an equal opportunity employer. We explicitly encourage female researchers to apply for the offered position. Among equally qualified applicants, disabled candidates will be given preference.

Please upload complete application documents including a cover letter, curriculum vitae and photocopies of relevant certificates as soon as possible via our online job-application facility using the button “Apply online”.

The advertisement is open with immediate effect and will remain open until the position will be filled.

We look forward to your application!
