Phases of Quasi-One-Dimensional Fractional Quantum (Anomalous) Hall - Superconductor Heterostructures
Steffen Bollmann, Andreas Haller, Jukka I. Väyrynen +2
Motivated by recent observations of fractional Chern insulators (FCIs) in the vicinity of superconducting (SC) phases, we study fractional quantum (anomalous) Hall-superconductor h…
Quantum Skyrmion Liquid
Dhiman Bhowmick, Andreas Haller, Deepak S. Kathyat +2
Skyrmions are topological magnetic textures, mostly treated classically, studied extensively due to their potential spintronics applications due to their topological stability. How…
Quantum and classical magnetic Bloch points
Vladyslav M. Kuchkin, Andreas Haller, Štefan Liščák +5
A Bloch point represents a three-dimensional hedgehog singularity of a magnetic vector field in which the magnetization vanishes. However, standard micromagnetic theory, developed…
