Job description

Experimental postdoc (ER) position within the Marie Curie Initial Training Network:  Cold Molecular Ions at the Quantum limit (COMIQ)

COMIQ is an European Commission funded network focused at educating Early Stage Researchers (ESR) at the PhD level within a range of advanced cooling, trapping, and control techniques with the purpose of developing cold molecular ion research beyond its present state. The aim of COMIQ is to investigate and control a variety of molecular ion processes at the very quantum limit. COMIQ will work on establishing cold molecular ions as new quantum objects for applications in quantum technology, precision measurements, and controlled chemistry. The network is highly interdisciplinary, combining quantum optics, quantum information sciences, molecular physics, and chemical physics in a novel and original fashion. The network consists of ten partners, both academic and industrial. 

Besides 13 PhD positions, COMIQ has a single Experience Researcher (ER) position at the coordinator node (Aarhus University, Denmark) from November 1st, 2013.

The role of the ER will be to take part in the research projects of the two ESRs at this node, as well as be assisting in coordinating the scientific program of the network. 

Please send your application to celia@phys.au.dk

Eligibility Criteria

In order to be eligible as an experienced researcher, the researcher must be in the first five years (full-time equivalent) of his/her research career and already in possession of a doctoral degree. The five-year period starts from the date when he/she obtained a degree, which would entitle him/her to start a doctorate. It is only the time that the researcher has spent carrying out research that counts towards the maximum 5 years’ experience.

The candidate must not have resided or carried out her/his main activity (work, studies, etc.) in the country of the host organisation for more than 12 months in the 3 years immediately prior to the recruitment. Short stays, such as holidays, are not counted. 

Contact

Candidates may contact scientific coordinator Prof. Michael Drewsen, drewsen@phys.au.dk, or administrative contact celia@phys.au.dk for general questions.

Publication: Observation of electric-dipole-forbidden infrared transitions in cold molecular ions

Prof. Stefan Willitsch at University of Basel publishes in Nature Physics.

Scheme of the experimental setup. LCE, laser control electronics (current driver and temperature controller); PA, preamplifier, bold arrows represent electrical current through the QCL.
Frequency noise PSD of the QCL measured in freerunning (A) and stabilized (B) conditions. The thin line above 100 kHz for the free-running QCL is an extrapolation of the 1∕f noise used for the linewidth determination. The “C” curve shows the frequency noise reduction achieved when stabilizing the QCL frequency to the side of the N2O transition using the same stabilization electronics and the optical signal from the MCT detector as an error signal. The corresponding full width at half-maximum (FWHM) linewidth of the laser calculated using the concept of the β-separation line [11] is also indicated in each case (at 10-ms observation time).
Simultaneous time series of the measured voltage, calculated electrical power and measured optical frequency fluctuations for the free-running (t < 10 ms) and stabilized (t > 10 ms) QCL.
