Are you also intrigued by the possibility of exploring macroscopic quantum phenomena? And do you want to pursue your scientific career in a world-leading research environment? Then please continue reading.
At the Center for Macroscopic Quantum States (bigQ) at DTU Physics, we seek an excellent, ambitious, and proactive experimentalist for a 2-year postdoc position to drive a recently initiated experimental project in the highly topical field of cavity optomechanics with bulk acoustic modes, and in close collaboration with a PhD student establish a state-of-the-art setup.
Our motivation is to investigate the Brillouin optomechanical coupling of bulk acoustic modes of crystalline resonators to an optical cavity field, and the first scientific objective is to demonstrate low-threshold strong coupling. The long-term visions include both fundamental investigations of macroscopic quantum phenomena as well as quantum information processing applications of the platform.
bigQ is a Danish national Center of Excellence in quantum information science and technology. The purpose of the center is to explore quantum physics in new macroscopic regimes, deepening our understanding of quantum physics, and speeding up the development of emerging quantum technologies. Our main focus is basic research, but we strongly encourage and support innovation and industry partnerships.
The center offers a stimulating and diverse working environment, comprising around 45 people (with 17 nationalities) including Faculty members, PhD students, postdocs, engineers and an administrator.
The project in short
Bulk acoustic optomechanics is a fast-developing field which has gained increased attention in recent years due to the direct access to the motional quantum ground state of bulk macroscopic systems and the ability to obtain ultra-long-lived high-frequency phononic modes.
In the first phase of the project, we will investigate the Brillouin optomechanical interaction in a room temperature setup but will later on transition to low temperature studies. In close collaboration with professionals in engineering and manufacturing of high-precision optical and mechanical assemblies, we have developed an innovative cavity system for operation at milli-Kelvin temperatures in our dilution refrigerator. We are confident that the system will provide us with the required competitive edge to reach our goals and deliver high-impact scientific results.
Responsibilities and qualifications
The project will be carried out in the optomechanics team of the bigQ center, including 4 PhD students, a Research Process Scientist, and one senior researcher. The team currently conducts research into optical feedback cooling of micro-mechanical resonators, development of ultra-coherent mechanical devices using topology optimisation, and theoretical quantum optomechanics. We expect you to actively engage in the team and contribute to and make your expertise available to all of the team’s activities.
We are looking for an exceptional physicist with extraordinary talents and outstanding drive. In particular, we are looking for academic excellence and/or demonstrated scientific achievements. We also expect you to have a strong ability to conceive new ideas, construct high-performance experimental setups, take initiative and leadership, and secure progress of the experimental work on a daily basis. Essential is your internal drive to achieve significant and ground-breaking results.
We expect you to,
You should be motivated and dedicated to do research of the highest standards, be able to work closely with other team members, and share our values of scientific curiosity and creativity. We require demonstrated expertise in experimental quantum optics, preferably with proficiency in optomechanics and ideally also with experience in cryogenics. Expertise in some of the following areas is expected:
- design and construction of room temperature optical setups,
- homodyne tomography,
- fiber optics,
- electronics development,
- numerical simulations,
- Python programming.
As a formal qualification, you must hold a PhD degree (or equivalent).
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice.
