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…
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…
Extracting transport coefficients from local ground-state currents
Felix A. Palm, Alexander Impertro, Monika Aidelsburger +1
Transport properties are central to characterizing quantum matter, yet their extraction typically requires external forcing and time-resolved measurements. In this work, we propose…
From hidden order to skyrmions: Quantum Hall states in an extended Hofstadter-Fermi-Hubbard model
Fabian J. Pauw, Ulrich Schollwöck, Nathan Goldman +2
The interplay between topology and strong interactions gives rise to a variety of exotic quantum phases, including fractional quantum Hall (FQH) states and their lattice analogs -…
Fractional Chern insulators on cylinders: Tao-Thouless states and beyond
Felix A. Palm, Chloé Van Bastelaere, Laurens Vanderstraeten
Topological phases in two-dimensional quantum lattice models are often studied on cylinders for revealing different topological properties and making the problem numerically tracta…
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…
