SUMMARY:Informal Quantum Seminar: Cristiano Muzzi - Salle des séminaires d
 u FAST et du LPTMS\, bâtiment Pascal n°530 - 4 Déc 26 14:00
DESCRIPTION:Towards quantum simulation of fingering instabilities in quantu
 m Hall droplets\nCristiano Muzzi (Université Libre de Bruxelles)\n&nbsp\;
 \nSystems of charged particles in a nonuniform magnetic field can exhibit 
 growth processes analogous to those observed for interfaces between two im
 miscible incompressible fluids with different viscosities\, a phenomenon k
 nown as Laplacian growth. In particular\, a quantum Hall droplet can devel
 op cusps driven by gradients of magnetic fields. This phenomenon is known 
 as fingering instability and has been deeply studied in classical fluid dy
 namics.\n\n\nIn this seminar\, I will show how the shape of the droplet ca
 n be predicted through a random matrix theory (plasma analogy) and to prob
 e this phenomenon\, in quantum Hall fluids. I will address this phenomenon
  dynamically by deforming an initially isotropic droplet by turning on mag
 netic fields far away from it. Studying this phenomenon in a lattice model
 \, beyond the limit of Aharonov-Casher wavefunctions\, I will show that th
 e formation of such patterns is a genuine feature of quantum Hall states. 
 Lattice effects and sudden deformations of the droplet are also studied. T
 o conclude\, I will discuss a quantum simulation setup in the continuum to
  observe this phenomenon in cold atomic gases in artificial gauge fields.\
