The focus of the first position is on studying the impurity physics in one-dimensional quantum liquids (e.g., interacting bosons or fermions in one dimension), which can be seen as one example of quantum Brownian motion. The work will be mainly done analytically although some numerical evaluations might be present. The student will learn and apply a number of techniques of theoretical physics including quantum field theory, Bethe ansatz, bosonization, effective field theories, etc.

The focus of the second position is on modeling of low-dimensional Wigner crystals (electrons with unscreened Coulomb interaction in external confining potentials). This work will involve significant amount of numerical evaluations for this many-body problem. The student will learn many-body physics on a concrete example of the realistic physical system that is recently realized in experiments.

Both positions are for 3 years with the provisional starting date in the Fall of 2023. Applicants with different backgrounds and expertises with interest in low-energy quantum physics of interacting particles are welcome to apply. To do so, please send your curriculum vitae, transcripts from master and bachelor studies and arrange for one or more letters of recommendation to be sent to Zoran Ristivojevic at ristivojevic@irsamc.ups-tlse.fr. Screening of applications will start immediately and will continue until the position is filled.
