<!-- ko if: isJobTitleVisible --> Postdoc in Topological Photonics – DTU Electro <!-- /ko --> <!-- ko if: isAlreadyAppliedVisible --><!-- /ko -->

The Quantum and Nanophotonics Section at DTU Electro is seeking a highly motivated postdoc to be a part of a program on ‘Symmetry-guided discovery of topological photonics’, led by Assoc. Prof. Thomas Christensen, who moved from MIT to DTU in early 2023.
The program aims to uncover novel kinds of photonic topology using recent ideas and tools at the intersection of topological band theory, symmetry analysis, and group theory. You will work on developing and applying these ideas to discover new photonic phenomena, implement associated computational tooling, and to find opportunities for proof-of-principles demonstrations with experimental collaborators. While the general theme of the postdoc will center on advancing the understanding of the interplay between photonic topology and symmetry in unexplored settings, the particulars are open and may encompass several directions. These directions may e.g., include inverse design of topologically nontrivial crystals or the pursuit of topology in non-Hermitian settings, under time-periodic driving (space-time symmetry), under magnetic symmetry, or even in non-crystalline settings.
The program aims to advance the frontiers of theoretical photonics, deepen our understanding of fundamental wave-phenomena, and investigate the applications of topology in photonics.
Responsibilities
You will carry out theoretical and computational work in topological photonics and nanophotonics. This will involve analyzing and computing topological properties of photonic structures, as well as planning and envisioning new research directions. The project is expected to involve approximately equal measure of analytical, computational, and exploratory work. You are expected to help advance the theoretical understanding, e.g., by development of new theoretical frameworks, applying existing frameworks, and implementing novel methodology in shared code repositories. You will also assist in instructing and guiding the research of MSc and PhD students.
Qualifications
As a formal qualification, you must hold a PhD degree (or equivalent).
Special consideration will be given to candidates with:

• A background in theoretical photonics or condensed matter physics
• First-rate mathematical ability
• Experience with symmetry analysis, group theory, or topological band theory
• Demonstrated experience in programming and contributions to open-source software
• Excellent communication skills, e.g., demonstrated by a track-record of high-impact publications
• Previous work in inverse design / topology optimization

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. 
The project will be supervised by Assoc. Prof. Thomas Christensen, and the postdoc is expected to interact and collaborate with his peer network, including at the Massachusetts Institute of Technology (MIT) and elsewhere in the US, Europe, and Asia.
Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.
The period of employment is 2 years. The starting date is as early as possible.
