Interplay of Band Geometry and Topology in Ideal Chern Insulators in Presence of External Electromagnetic Fields
Christian Northe, Giandomenico Palumbo, Jonathan Sturm +2
Ideal Chern insulating phases arise in two-dimensional systems with broken time-reversal symmetry. They are characterized by having nearly-flat bands, and a uniform quantum geometr…
Non-Relativistic Supergeometry in the Moore-Read Fractional Quantum Hall State
Patricio Salgado-Rebolledo, Giandomenico Palumbo
The Moore-Read state is one the most well known non-Abelian fractional quantum Hall states. It supports non-Abelian Ising anyons in the bulk and a chiral bosonic and chiral Majoran…
Fractional Quantum Hall Effect for Extended Objects: from Skyrmionic Membranes to Dyonic Strings
Giandomenico Palumbo
It is well known that in two spatial dimensions the fractional quantum Hall effect (FQHE) deals with point-like anyons that carry fractional electric charge and statistics. Moreove…
Band topology of pseudo-Hermitian phases through tensor Berry connections and quantum metric
Yan-Qing Zhu, Wen Zheng, Shi-Liang Zhu +1
Among non-Hermitian systems, pseudo-Hermitian phases represent a special class of physical models characterized by real energy spectra and by the absence of non-Hermitian skin effe…
Extended Nappi-Witten Geometry for the Fractional Quantum Hall Effect
Patricio Salgado-Rebolledo, Giandomenico Palumbo
Motivated by the recent progresses in the formulation of geometric theories for the fractional quantum Hall states, we propose a novel non-relativistic geometric model for the Laug…
Non-Abelian tensor Berry connections in multi-band topological systems
Giandomenico Palumbo
Here, we introduce and apply non-Abelian tensor Berry connections to topological phases in multi-band systems. These gauge connections behave as non-Abelian antisymmetric tensor ga…
