Open Postdoc Position at ENS (Lab. Kastler Brossel): Single-atom imaging of correlated quantum matter

Our group at École Normale Supérieure in Paris is searching for a highly qualified post-doc with experience in the field of quantum gases. The selected candidate will join a cutting edge project devoted to the imaging and manipulation of correlated quantum gases at the single-atom level. Two specific systems will be explored (i) the Unitary Fermi gas and (ii) quantum Hall liquids. The experiments will take place on a new generation quantum gas machine operating with Lithium 6 under the supervision of Tarik Yefsah.  

The selected candidate, in addition to contributing to the experimental work, is expected to undertake managerial tasks involving supervision of students, lab logistics as well as the planning of experiments with the PI.

Scientific Context

The general context of this research project is the understanding of low temperature strongly-correlated quantum matter. Strongly-correlated fermions are ubiquitous in nature, from the quark-gluon plasma of the early universe to neutron stars, they lie as well at the heart of many modern materials such as high-temperature superconductors, colossal magneto-resistance devices or graphene. While being a pressing issue covering a wide fundamental and technological scope, the understanding of strongly-correlated fermions constitutes a serious challenge of modern physics, which is often hindered by the complexity of the host systems themselves. The contribution of ultracold gas experiments in this quest resides in the ability to set fermions in a well-characterized environment, where one can add a single ingredient at a time (spin mixture, interactions, lattice, etc) with a high degree of control, allowing for an incremental complexity, which represents an ideal playground for a direct comparison to many-body theories.
