Postdoc Position in quantum optomechanics with polaritons
Project Description:
- The project aims to unlock quantum regime of optomechanics with polaritons by utilizing GaAs/AlAs-based microcavities with embedded quantum wells. These unconventional optomechanical systems exhibit a unique "magic coincidence" of their phonon and polariton properties allowing for the simultaneous trapping of light and sound within the same high-Q cavity, and resulting in extremely high optomechanical interaction for the polaritons and mechanical modes in GHz range. The project is carried out in close collaboration with leading experts in semiconductor cavity optomechanics in Berlin, providing access to complementary expertise and device know-how.
- We aim to cool mechanical degrees of freedom deeply into their quantum ground state and observe sideband asymmetry, using dilution refrigerator with optical access and free space interferometry. Beyond ground state cooling, the project targets bi-partite quantum states preparation and coherent control of phonons and polaritons. The successful candidate will join the MQO-QNOF team at Aalto University and build a state-of-the-art cryogenic optical experiment combining advanced interferometry, quantum optics techniques, and unique semiconductor cavity structures unavailable elsewhere.
Key responsibilities include:
- The successful candidate is expected to lead the experimental effort with a team of PhD and master’s students and collaborate closely with theorists in the group. They will collaborate with our academic and industry partners worldwide. They expected to lead preparation of research manuscripts for publications in top-tier journals, coordinate submissions, and taking the role of corresponding author. Besides the expertise in experimental quantum optics, the candidate will acquire excellent training in grant writing and research leadership provided by Aalto University and at the MQO/QNOF group level by contributing to research management and funding applications within the joint team.
Required Qualification:
Essential Qualification:
- PhD in one of the following broader experimental areas: quantum optics/optomechanics, AMO physics, advanced laser spectroscopy and interferometry
- Strong hands-on skills in experimental research (optics lab), including automation of data acquisition and data analysis
- Proven track record of research publications in your field
- Excellent communication skills (fluency in English) and strong collaboration abilities
- Finnish language is not required
- Highly motivated to conduct fundamental research
Preferred Qualification:
Not Available
Employment Conditions and Benefits:
