Quantum Hall Effect without Chern Bands
Benjamin Michen, Jan Carl Budich
The quantum Hall effect was originally observed in a two-dimensional electron gas forming Landau levels when exposed to a strong perpendicular magnetic field and was later generali…
Adiabatic preparation of a number-conserving atomic Majorana phase
Benjamin Michen, Tim Pokart, Jan Carl Budich
We construct a protocol to adiabatically prepare the ground state of a widely discussed number-conserving model Hamiltonian for ultracold atoms in optical lattices that supports Ma…
Exceptional Luttinger Liquids from sublattice dependent interaction
J. Schwardt, B. Michen, C. Lehmann +1
We demonstrate how Exceptional Points (EPs) naturally occur in the Luttinger Liquid (LL) theory describing the low-energy excitations of a microscopic lattice model with sublattice…
Non-Linear Interference Challenging Topological Protection of Chiral Edge States
Benjamin Michen, Jan Carl Budich
We report on a non-linear scattering effect that challenges the notion of topological protection for wave packets propagating in chiral edge modes. Specifically, in a Floquet topol…
Adiabatic preparation of fractional Chern insulators from an effective thin-torus limit
Benjamin Michen, Cécile Repellin, Jan Carl Budich
We explore the quasi one-dimensional (thin torus, or TT) limit of fractional Chern insulators (FCIs) as a starting point for their adiabatic preparation in quantum simulators. Our…
Mesoscopic transport signatures of disorder-induced non-Hermitian phases
Benjamin Michen, Jan Carl Budich
We investigate the impact on basic quantum transport properties of disorder-induced exceptional points (EPs) that emerge in a disorder-averaged Green's function description of two-…
Exceptional Non-Hermitian Phases in Disordered Quantum Wires
Benjamin Michen, Tommaso Micallo, Jan Carl Budich
We demonstrate the occurrence of nodal non-Hermitian (NH) phases featuring exceptional degeneracies in chiral-symmetric disordered quantum wires, where NH physics naturally arises…
