There are two postdoc and two PhD student positions on molecular quantum nanophotonics available in the group of Johannes Feist at IFIMAC and the Departamento de Física Teórica de la Materia Condensada at the Universidad Autónoma de Madrid.
These positions are financed by the ERC Starting Grant MMUSCLES (Modification of Molecular structure Under Strong Coupling to confined Light modES).
Within the ERC Consolidator Grant project COMOTION — CONTROLLING THE MOTION OF COMPLEX MOLECULES AND PARTICLES there are several position openings.
For instance, the following two projects, amongst others, are open and to be filled as soon as possible. Further project descriptions are available at https://www.controlled-molecule-imaging.org/careers/projects
Aerosols into vacuum
This project will develop strategies to optimally transfer large molecules/particles into high-vacuum through nebulization techniques, possibly combined with aerodynamic transport and focusing. Techniques include gas-dynamics-virtual-nozzle thin water jets, electrospray, and other analytical chemistry nebulization techniques, which will be combined with special aerodynamic lenses currently being developed in our group. This includes methodologies to cryogenically cool the produced beams. The resulting (bio)particle beams will be thoroughly characterized (density, distribution, charge-state,…) and applied in fundamental physics and biochemistry/structural biology studies. Subsequently, the experiments will be extended toward the control of these beams (mass selection, isomer separation, angular alignment).
The produced and well-controlled cold samples of large molecules/nanoparticles will be investigated using femtosecond lasers and with x-ray or electron diffraction experiments, using table-top (laboratory) as well as at Free-Electron laser sources.
The successful candidate will have an outstanding Ph.D. in experimental physics, physical chemistry, or a related field. Experience with aerosol technologies, lasers, vacuum equipment, or diffractive imaging is highly desirable.

Control of aerodynamically focussed beams of very large molecules and nanoparticles
In this project we develop strategies to control the transfer of very large molecules and nanoparticles to the interaction point of modern imaging experiments, in high-vacuum, through the use of cryogenic techniques and optical manipulation. “Shock-freezing” the molecules makes them especially amenable to the control of their internal and external degrees of freedom. External electric and laser fields allow for precise steering of the particles as well as for spatial separation based on physical properties (size, mass, structure). Methodologies to characterize these beams regarding density, distribution, charge-state, etc will be further developed.
The produced and well-controlled cold samples of very large molecules/nanoparticles will be investigated using X-ray or electron diffraction experiments in laboratory experiments, as well as at Free-Electron lasers.

CFEL Molecular Physics – Controlled Molecule Imaging
The Controlled Molecule Imaging group (CMI) develops methods to control complex
molecules in the gas phase. Currently, we are extending our research toward very large molecules and particles based on funding through a European Research Council (ERC)
Consolidator Grant “COMOTION”: Controlling the motion of very large molecules and particles.
We are looking for highly motivated individuals with a strong background in the physical sciences, for instance, in theoretical or experimental atomic or molecular physics, physical chemistry, quantum optics, or laser physics. A strong foundation in quantum mechanics is necessary, experience with lasers, vacuum equipment, and programming skills are an advantage. Curiosity and motivation for groundbreaking science is assumed.
