Anyon-Impurity Bound States in Quantum-Engineered Fractional Chern Insulators
Botao Wang, Amit Vashisht, Felix A. Palm +3
Mobile impurities provide a powerful means of probing correlated and topological quantum matter, through their dressing by the surrounding medium and the practical probes granting…
Exact statistical transmutation of quantum mixtures on a ring
Wayne J. Chetcuti, Nathan Goldman, Patrizia Vignolo +1
One-dimensional strongly repulsive quantum mixtures exhibit non-trivial exchange statistics arising from the interplay between orbital and spin degrees of freedom. Using an exact s…
Edge-state interferometry as a probe of local flux in isolated quantum Hall systems
Botao Wang, Nathan Goldman, André Eckardt
Quantum point contacts (QPCs) are essential tools for transport experiments in solid-state systems, enabling the detection of fractional charges and anyonic braiding statistics. Re…
Vortex NOON states for rotation sensing
Simon Dengis, Nathan Dupont, Peter Schlagheck +1
We introduce a scheme to generate NOON states of few-body bosonic vortices and demonstrate their application as high-precision rotation sensors. Our approach is based on cold atoms…
Interferometric Braiding of Anyons in Chern Insulators
Felix A. Palm, Nader Mostaan, Nathan Goldman +1
Coherent control and braiding of anyons remain central challenges in realizing topologically protected quantum operations. We propose a Ramsey interferometry protocol to directly a…
Fractional Quantum Hall Wedding Cakes
Chloé Van Bastelaere, Felix A. Palm, Botao Wang +2
This work investigates the coexistence of distinct topologically ordered phases within a single setup. We demonstrate this concept through tensor network simulations of the Hofstad…
