Long-Range Order and Composite Boson Condensation in Lattice Quantum Hall States
Fabian J. Pauw, Nathan Goldman, Felix A. Palm
Topological states of matter, such as quantum Hall states, are characterized by the absence of local order parameters. In the continuum, their topological order has been reinterpre…
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…
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…
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 -…
Absence of gapless Majorana edge modes in few-leg bosonic flux ladders
Felix A. Palm, Cécile Repellin, Nathan Goldman +1
The search for Majorana excitations has seen tremendous efforts in recent years, ultimately aiming for their individual controllability in future topological quantum computers. A p…
Neural Network Quantum States for the Interacting Hofstadter Model with Higher Local Occupations and Long-Range Interactions
Fabian Döschl, Felix A. Palm, Hannah Lange +2
Due to their immense representative power, neural network quantum states (NQS) have gained significant interest in current research. In recent advances in the field of NQS, it has…
Detecting Hidden Order in Fractional Chern Insulators
Fabian J. Pauw, Felix A. Palm, Ulrich Schollwöck +3
Topological phase transitions go beyond Ginzburg and Landau's paradigm of spontaneous symmetry breaking and occur without an associated local order parameter. Instead, such transit…
Growing Extended Laughlin States in a Quantum Gas Microscope: A Patchwork Construction
Felix A. Palm, Joyce Kwan, Brice Bakkali-Hassani +4
The study of fractional Chern insulators and their exotic anyonic excitations poses a major challenge in current experimental and theoretical research. Quantum simulators, in parti…
Ferromagnetism and Skyrmions in the Hofstadter-Fermi-Hubbard Model
Felix A. Palm, Mert Kurttutan, Annabelle Bohrdt +2
Strongly interacting fermionic systems host a variety of interesting quantum many-body states with exotic excitations. For instance, the interplay of strong interactions and the Pa…

Felix A. Palm, Sam Mardazad, Annabelle Bohrdt +2
Experimental realizations of topologically ordered states of matter, such as fractional quantum Hall states, with cold atoms are now within reach. In particular, optical lattices p…
Symmetry-protected Bose-Einstein condensation of interacting hardcore Bosons
R. H. Wilke, T. Köhler, F. A. Palm +1
We introduce a mechanism stabilizing a one-dimensional quantum many-body phase, characterized by a certain wave vector , from a -modulated coupling to a center site, via…
