Berry Phases in the Bosonization of Nonlinear Edge Modes
Mathieu Beauvillain, Blagoje Oblak, Marios Petropoulos
We consider chiral, generally nonlinear density waves in one dimension, modelling the bosonized edge modes of a two-dimensional fermionic topological insulator. Using the coinciden…
Quantum Hall edges beyond the plasma analogy
Per Moosavi, Blagoje Oblak, Bastien Lapierre +2
We demonstrate that the widely used plasma analogy is unreliable at predicting edge properties of quantum Hall states. This discrepancy arises from a fundamental difference between…
Anisotropic Quantum Hall Droplets
Blagoje Oblak, Bastien Lapierre, Per Moosavi +2
We study two-dimensional (2D) droplets of noninteracting electrons in a strong magnetic field, placed in a confining potential with arbitrary shape. Using semiclassical methods ada…
Adiabatic Deformations of Quantum Hall Droplets
Blagoje Oblak, Benoit Estienne
We consider area-preserving deformations of the plane, acting on electronic wavefunctions through "quantomorphisms" that change both the underlying metric and the confining potenti…
Ergodic Edge Modes in the 4D Quantum Hall Effect
Benoit Estienne, Blagoje Oblak, Jean-Marie Stéphan
The gapless modes on the edge of four-dimensional (4D) quantum Hall droplets are known to be anisotropic: they only propagate in one direction, foliating the 3D boundary into indep…
