The Institute of Physics at the University of Amsterdam is offering 3 PhD positions In Experimental Quantum Physics in the 2020/21 academic session.

Project details:

ESR1 – Compact atomic sources and beams for steady-state superradiant lasers 
Steady-state atomic beam sources are crucial to realizing superradiant clocks and beneficial for quantum sensing with ultracold atoms in general. They have developed a continuous beam of ultracold atoms of unprecedented brightness and phase-space density and can create steady-state Bose-Einstein condensates. This continuous source of atoms is one of the foundations of our attempts to develop continuous superradiant clocks within iqClock.

ESR2 – Precision laser stabilization and locking 
The core of ESR2’s project is to develop an ultrastable laser and use it for research. ERS2 will build an ultrastable, high-finesse cavity and lock a laser to it such that it has a linewidth well below 1 Hz. Light will be sent from this laser through phase-stabilized fibre links to the superradiant clock we develop within iqClock and serve to characterize its precision. These characterizations will be used to identify precision limiting effects and to improve the clock. A further research opportunity is to use this laser for internal state control in our programmable quantum simulator. Another aspect of ESR2’s work will be the development of a scalable and simple system to lock all lasers required to operate a superradiant clock.

ESR3 – High finesse cavities for strong atom-light interaction 
High-finesse cavities loaded with ultra-cold atoms are a key to future applications harnessing strong atom-light interactions. These include superradiant optical clocks, sensors, quantum memories, quantum simulation and quantum information processing. As part of our goal of making a steady-state superradiant optical clock we are developing high finesse UHV vacuum cavities that can be loaded with ultracold strontium atoms. For steady-state operation we need to continuously and efficiently load atoms from the ultra-cold strontium beam developed by ESR1 into the cavity. Furthermore, the atoms in the cavity need to be held tightly by a magic wavelength lattice, which doesn’t shift the Sr clock frequency. ESR3 will work closely with the iqClock team on all these topics.
