Counting interacting electrons in one dimension
Oleksiy Kashuba, Thomas L. Schmidt, Fabian Hassler +2
The calculation of the full counting statistics of the charge within a finite interval of an interacting one-dimensional system of electrons is a fundamental, yet as of now unresol…
Perfectly localized Majorana corner modes in fermionic lattices
Prathyush P. Poduval, Thomas L. Schmidt, Andreas Haller
Focusing on examples of Majorana zero modes on the corners of a two-dimensional lattice, we introduce a method to find parameter regions where the Majorana modes are perfectly loca…
Black hole mirages: electron lensing and Berry curvature effects in inhomogeneously tilted Weyl semimetals
Andreas Haller, Suraj Hegde, Chen Xu +3
We study electronic transport in Weyl semimetals with spatially varying nodal tilt profiles. We find that the flow of electrons can be guided precisely by judiciously chosen tilt p…
Overlap of parafermionic zero modes at a finite distance
Raphael L. R. C. Teixeira, Andreas Haller, Roshni Singh +4
Parafermion bound states (PBSs) are generalizations of Majorana bound states (MBSs) and have been predicted to exist as zero-energy eigenstates in proximitized fractional quantum H…
Quantum Skyrmion Lattices in Heisenberg Ferromagnets
Andreas Haller, Solofo Groenendijk, Alireza Habibi +2
Skyrmions are topological magnetic textures that can arise in non-centrosymmetric ferromagnetic materials. In most systems experimentally investigated to date, skyrmions emerge as…
Supersolid-Superfluid phase separation in the extended Bose-Hubbard model
Korbinian Kottmann, Andreas Haller, Antonio Acín +2
Recent studies have suggested a new phase in the extended Bose-Hubbard model in one dimension at integer filling [1,2]. In this work, we show that this new phase is phase-separated…
