Spectral signatures of hidden order and hidden quantum critical points
Reja H. Wilke, Henning Schlömer, Sebastian Paeckel +2
Hidden-order phases elude the conventional Ginzburg-Landau framework: although they spontaneously break symmetry, their order remains invisible to standard local two-point correlat…
Ensembles of random quantum states tunable from volume law to area law
Héloïse Albot, Sebastian Paeckel
A standard approach to generate random pure quantum states relies on sampling from the Haar measure. However, the entanglement properties of such states present a fundamental chall…
Two-channel physics in a lightly doped antiferromagnetic Mott insulator revealed by two-hole spectroscopy
Pit Bermes, Sebastian Paeckel, Annabelle Bohrdt +2
Understanding pairing in the strong-coupling regime of doped Mott insulators remains an open problem in the context of cuprate superconductors. We perform ultra-high resolution num…

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…
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…
Towards effective models for low-dimensional cuprates: From ground state Hamiltonian reconstruction to spectral functions

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 -…
A Tensor Network Framework for Lindbladian Spectra and Steady States
