A Tensor Network Framework for Lindbladian Spectra and Steady States
Philipp Westhoff, Mattia Moroder, Ulrich Schollwöck +1
Quantum systems coupled to (non-)Markovian environments attract increasing attention due to their peculiar physical properties. Exciting prospects such as unconventional non-equili…
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…
Matter-induced plaquette terms in a lattice gauge theory
Matjaž KebriÄ, Fabian Döschl, Umberto Borla +4
Lattice gauge theories (LGTs) provide a powerful framework for studying confinement, topological order, and exotic quantum matter. In particular, the paradigmatic phenomenon of con…
Large Isolated Stripes on Short 18-leg - Cylinders
Tizian Blatz, Sebastian Paeckel, Ulrich Schollwöck +2
Spin-charge stripes belong to the most prominent low-temperature orders besides superconductivity in high-temperature superconductors. This phase is particularly challenging to stu…
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 -…
Exploring confinement transitions in lattice gauge theories with dipolar atoms beyond one dimension
Matjaž KebriÄ, Lin Su, Alexander Douglas +6
Confinement of particles into bound states is a phenomenon spanning from high-energy to condensed matter physics, which can be studied in the framework of lattice gauge theories (L…
