The Institut of Quantum Optics invites applications for three positions of a
Research Assistant (m/f/d)
in the field of Experimental Physics
(Salary Scale 13 TV-L, 75 %)
starting as soon as possible. The positions are initially limited to 3 years each and offer the possibility of receiving a doctorate.
Responsibilites and duties
1) Roadmap to a microtechnological quantum gravimeter
Analogous to the Laser in the field of optical interferometry, the use of Bose-Einstein condensates (BEC) represents a decisive advantage for atomic interferometry. Important methods in this field have been developed in our group and laboratory-filling setups have been transferred into transportable systems using the atom chip technology. Similar to the development of MEMS sensors (Micro-electro-mechanical systems), atom interferometers can be further miniaturized by utilizing microproduction technologies.
In interdisciplinary collaboration with engineers and industry, a quantum optical sensor based on cold or ultra-cold atoms shall be miniaturized and simplified using nanostructures. First studies on the micro-quantum system will be carried out with the collaborative partners and its performance should be evaluated for the use as an inertial sensor.
The tasks include electromagnetic computer simulations in the design phase, independent planning and construction of electrical and optical systems, and the planning, execution and evaluation of quantum optical experiments.
2) Methods for miniaturized quantum sensors
The miniaturization of quantum systems into smaller and smaller volumes requires the use of novel methods in atom interferometry to maintain the sensitivity of the sensor. As an alternative to simple freefall, atoms can be "juggled" in optical lattices or held in a guided trap instead. The basic feasibility of these methods has already been demonstrated in the group.
The project will investigate these methods in more detail and use them to realize a miniaturized, transportable quantum sensor that will be fabricated in collaboration with engineers in a partner project. The product will serve as a prototype for a transportable and compact atom chip fountain gravimeter.
Concrete tasks include the independent planning, construction and characterization of a compact and transportable laser system with regard to its use in atom interferometry as well as the planning, execution and evaluation of quantum optical experiments.
3) Absolute Quantum Gravimetry in Flight (PI: Dr. Dennis Schlippert)
The successful candidate will independently work on the realization of a quantum gravimeter for operation on aircraft in the frame of the “Leuchtturmprojekts AeroQGrav – Absolute Aero Quantengravimetrie”. Work will be conducted in close collaboration with project partners at DLR-SI and geo++ GmbH and is particularly focused on the conception and setup of sensor periphery and integration of auxiliary sensors, mainly for suppressing the influence of vibrational noise, and the sensor’s electronics system. Furthermore, the candidate will be involved in the commissioning and testing of the sensor including flight campaigns.
To qualify for the position, applicants must hold a scientific university degree (Master, Diploma, or equivalent) in physics, photonics, quantum engineering, or comparable curricula. Very good knowledge of quantum optics and atomic and molecular physics is beneficial. We require very good written and spoken English, organizational skills, own initiative, and the ability and willingness to familiarize oneself with new areas of work.
