Postdoc in Ultrafast Spectroscopy of Quantum Emitters in Layered Materials and Molecules DTU Electro

Postdoc opportunity in ultrafast spectroscopy of quantum emitters in the layered material hexagonal Boron Nitride (hBN) and molecular systems. Recent experiments also performed in our group have shown that luminescent centers in hBN are excellent candidates for the development of future light-based quantum technologies working close to or at room temperature.

In the Quantum Photonics in Low-Dimensional System Group at the Technical University of Denmark (DTU) we are looking for motivated and talented scientists holding a PhD in ultrafast optics and quantum nanophotonics to perform spectroscopy of the quantum coherence properties of promising quantum emitters in hBN and molecular systems. Our group belongs to the Quantum and Nanophotonics Section of the Department of Electrical and Photonics Engineering (DTU Electro).

Funded by a Novo Nordisk Foundation New Exploratory Research and Discovery program the project led by Associate Professor Nicolas Stenger aims to deepen our fundamental understanding of phonon-induced decoherence in quantum emitters in layered materials a major hurdle for the development of light-based quantum technologies beyond cryogenic environments.

You will work on developing a unique ultrafast spectroscopy technique to quantify in the influence of phonons on the quantum dynamics of quantum emitters in hBN and molecular systems. You will work in close collaboration with experts in ultrafast spectroscopy at DTU Electro as well as theoreticians in our group and one of the world experts in phonon-induced decoherence in quantum emitters Dr. Jake Iles-Smith from the University of Sheffield.

Responsibilities
Your main responsibility will be to implement a unique ultrafast spectroscopic method able to track the dissipation processes in quantum emitters induced by the phononic environment. You will benefit from the long experience in ultrafast spectroscopy available at DTU Electro and adapt state-of-the-art methods to be able to track the electronic photonic and phonon dynamics in these systems. This will involve the testing of a new ultrafast spectroscopic setup in particular its performance in terms of temporal resolutions and energy tunability. You will analyze the experimental data and compare them to theoretical predictions. You are expected to have an excellent understanding of quantum nanophotonics of optical spectroscopy and of experimental laser physics. You can work independently and communicate efficiently with a team of experts in the field. You will also have the opportunity to nurture and develop your own ideas as well as to guide and supervise MSc and PhD students.

Qualifications

• As a formal qualification you must hold a PhD degree (or equivalent)in physics photonics engineering or a related topic.
• A strong background in laser spectroscopy and solid state physics
• A good understanding of solid state-based quantum emitters and quantum nanophotonics
• Excellent communication skills e.g. demonstrated by a track-record of high-impact publications
• Interest in the supervision and mentoring of students
