Gauging modulated symmetries: Kramers-Wannier dualities and non-invertible reflections

SD Pace, G Delfino, HT Lam, ÖM Aksoy - SciPost Physics, 2025 - scipost.org
Modulated symmetries are internal symmetries that act in a non-uniform, spatially modulated
way and are generalizations of, for example, dipole symmetries. In this paper, we …

The charge gap is greater than the neutral gap in fractional quantum Hall systems

M Lemm, B Nachtergaele, S Warzel… - arxiv preprint arxiv …, 2024 - arxiv.org
Past studies of fractional quantum Hall systems have found that the charge gap dominates
the neutral gap for all relevant parameter choices. We report a wide-ranging proof that this …
