Universality in the number variance and counting statistics of the real and symplectic Ginibre ensemble

G Akemann, SS Byun, M Ebke… - Journal of Physics A …, 2023 - iopscience.iop.org
In this article, we compute and compare the statistics of the number of eigenvalues in a
centred disc of radius R in all three Ginibre ensembles. We determine the mean and …

Cumulants and large deviations for the linear statistics of the one-dimensional trapped Riesz gas

PL Doussal, G Schehr - arXiv preprint arXiv:2408.04437, 2024 - arxiv.org
We consider the classical trapped Riesz gas, ie, $ N $ particles at positions $ x_i $ in one
dimension with a repulsive power law interacting potential $\propto 1/| x_i-x_j|^{k} $, with …

Noncommutative geometry and deformation quantization in the quantum Hall fluids with inhomogeneous magnetic fields

G Palumbo - Journal of Physics A: Mathematical and Theoretical, 2023 - iopscience.iop.org
It is well known that noncommutative geometry naturally emerges in the quantum Hall states
due to the presence of strong and constant magnetic fields. Here, we discuss the underlying …

Quantum Hall Edges Beyond the Plasma Analogy

P Moosavi, B Oblak, B Lapierre, B Estienne… - arXiv preprint arXiv …, 2024 - arxiv.org
We demonstrate that the plasma analogy is generally unreliable at predicting the edge
properties of quantum Hall (QH) states, as it fails to account for the local edge velocity. This …

Berry Phases in the Bosonization of Nonlinear Edge Modes
