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…

Adaptive Pseudoboson Density-Matrix Renormalization Group for Dilute 2D Systems
Fabian J. Pauw, Thomas Köhler, Ulrich Schollwöck +1
Simulating strongly correlated systems in two dimensions is notoriously challenging due to rapid entanglement growth and frustration. Here, we introduce the adaptive projected-puri…

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 -…
