In this project you will couple tunable optical microcavities with nanostructured excitonic materials to achieve strong photon-photon interactions. You will use these interactions to investigate phase transitions of light, and to evidence the conditions under which noise can enhance the transport of excitations in complex systems. By designing cavity arrays with different dimensionalities and geometries, you will tailor the potential landscape in which photons hop and interact. This will allow you to emulate the behaviour of condensed matter systems with light.
You will be primarily involved in all aspects of the design, realization, and analysis of experiments. In synergy with another group member and the group leader, you will build two optical setups:
i) a tunable cavity system that can be moved to other labs at AMOLF. This will allow you to probe the nonlinear optical response of hybrid light-matter states using ultrafast lasers. Here the aim is to investigate the physics of quantum fluids of light (e.g. a superfluid) at room-temperature.
ii) a low-temperature tunable cavity system suitable for nonlinear and quantum optical experiments. Here the aim is to investigate non-equilibrium phase transitions by measuring the nonlinear dynamics of single and coupled microcavities under the influence of quantum fluctuations. You will control the strength of the photon-photon interactions via the tunable cavity, and the influence of the quantum fluctuations by tuning the frequency of the driving laser.
Through these projects you will become an expert in hybrid light-matter systems, nonlinear optics, quantum optics, and condensed matter physics. You will collaborate with other AMOLF groups synthetizing organic and inorganic materials that you will place inside microcavities, and with colleagues at the University of Oxford in the design novel microcavity arrays. You will also develop theory, and work closely with theoretical groups, to interpret your experimental results.
Terms of employment
The position is intended as full-time (40 hours / week, 12 months / year) appointment in the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of 4 years in the case of a PhD. For a postdoc, the intended duration is 2 years, with possibility to extend an extra year upon satisfactory performance. AMOLF assists any new PhD or postdoc with housing and visa applications and compensates their transport costs.
Required qualifications
For the PhD: You have (or will get soon) a MSc in Physics or closely-related discipline. Lab experience in optics/photonics is preferable, but not strictly necessary.
For the Postdoc: You have (or will get soon) a PhD in Physics or closely-related discipline. Lab experience in optics/photonics is required.
For PhD and postdoc: A background or strong interest in any of the following is valued: nonlinearity, quantum optics, coupled systems, condensed matter, stochastic systems. This project involves multiple collaborations, so we are looking for a team-player.
