About this position
The University of Copenhagen’s Niels Bohr Institute invites applications for two three-year Postdoctoral Researcher positions in experimental nanophotonics and quantum optics in Professor Maiken H. Mikkelsen’s group.
The group investigates how light and matter interact when light is confined to nanometre-scale volumes. Its work uses deterministically fabricated plasmonic nanocavities—metallic nanogaps formed around selected emitters—to access exceptionally strong light–matter interactions, including enhanced spontaneous emission, single-photon generation at telecom wavelengths, and highly enhanced second-harmonic generation.
The research programme covers three connected directions. Spatial control focuses on shaping the optical vacuum around emitters, concentrating fields for nonlinear optics, and studying phenomena such as Purcell tensors, nanophotonic Lamb shifts, nanoscale harmonic generation, and transitions enabled by field gradients. Emitter-number control addresses cavity quantum electrodynamics with one or more emitters, strong coupling, collective emission, and multi-exciton processes. Temporal control involves ultrafast and time-resolved experiments on individual nanocavities, quantum materials embedded in nanogaps, optically dressed states, pump–probe spectroscopy, and time-varying cavities.
Postdoctoral researchers will conduct experimental research and help establish the group’s new laboratory at the Niels Bohr Institute. The facilities include a 1.7 K cryostat with vector magnet, a tunable femtosecond laser system, and single-photon confocal spectroscopy. Researchers will also fabricate cavities in the NBI cleanroom and at DTU Nanolab, Denmark’s national nanofabrication centre, and may collaborate with national and international partners.
The successful researchers will contribute to publications and presentations, participate in student supervision, and help shape the group’s first experiments at the new laboratory. The programme welcomes candidates who wish to develop independent research directions within experimental nanophotonics, quantum optics, cavity QED, cryogenic spectroscopy, ultrafast optics, or nanofabrication.
Funding details
The positions are three-year postdoctoral appointments. Salary and employment terms follow the Danish state-sector agreement for academic staff; negotiation of a salary supplement is possible. No specific salary amount or tuition funding is stated.
What's required
Applicants must hold a PhD in physics, chemistry, materials science, electrical engineering, or a closely related discipline, or provide documentation of the expected PhD completion date. Candidates should be outstanding, creative, highly motivated experimentalists with a strong background in one or more of nanophotonics or cavity QED, quantum optics and photon-correlation measurements, cryogenic spectroscopy of solid-state emitters or two-dimensional materials, ultrafast optical spectroscopy, or nanofabrication. Applications must include an English cover letter describing motivation and research interests of no more than one page, a curriculum vitae including publication list, Master's and PhD diplomas or expected-completion documentation, and contact details for two or three references. Candidates may propose their own research directions within the programme scope.
