Missions
The fractional quantum Hall effect is typically realized in two-dimensional solids in the presence of a strong magnetic field. In neutral ultra-cold atomic gases, it is possible to implement an effective magnetic field thanks to optical gauge field engineering. The realization of a fractional quantum Hall state in these systems is actively pursued by experimental groups, and permits a new perspective onto this exotic physics.
The goal of this project is to propose new protocols to characterize fractional quantum Hall states of cold atoms, particularly those supporting non-abelian anyons.
Activités
The candidate will develop new protocols based on techniques available in cold atom experiments, to extract universal signatures of topological order, such as the exchange statistics of anyons, or the critical field theory at the edge. We will consider in particular the dynamics following a local or global perturbation, as well as the response to an adiabatic change. These protocols will be tested using numerical techniques such as exact diagonalization and DMRG (Density Matrix Renormalization Group).
Compétences
Prerequisite: PhD in theoretical condensed matter physics
Desirable skills:
Expertise of numerical techniques for many-body quantum physics, preferrably DMRG and / or exact diagonalization
Contexte de travail
This project is part of the NAbelianChern grant funded by the ANR.
The hosting institute is the Laboratory of Physics and Modeling of Condensed Matter, which is located at the heart of Grenoble's scientific polygon. It is a small theory laboratory (13 permanent researchers), within the large quantum condensed matter pole in Grenoble. This institute fosters a strong expertise of quantum many-body physics, and its analytical and numerical techniques, and the postdoctoral researcher will be strongly encouraged to benefit from this environment through day to day discussion and collaboration with the other researchers. Likewise, there will be many opportunities to interact with LPMMC's direct theory and experiment neighbors at Institut Néel, LNCMI and CEA, on topics such as the fractional quantum Hall effect, 2D materials, or frustrated magnetism.
Start date as soon as possible, between January 1st and June 1st 2026
Total duration of the project is 24 months.
