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 -…
