Evolution of superconductivity from charge clusters to stripes in the -- model
Aritra Sinha, Hannes Karlsson, Martin Ulaga +1
Competition and coexistence of charge orders and superconductivity are hallmarks in many strongly correlated electron systems. Here, we unravel the precise role of charge fluctuati…
Cooper Condensation and Pair Wave Functions in Strongly Correlated Electrons
Hannes Karlsson, Johannes S. Hofmann, Alexander Wietek
Identifying superconducting states of matter without prior assumptions is a central challenge in strongly correlated electron systems. We introduce a canonical framework for diagno…
XDiag: Exact Diagonalization for Quantum Many-Body Systems
Alexander Wietek, Luke Staszewski, Martin Ulaga +6
Exact diagonalization (ED) is a cornerstone technique in quantum many-body physics, enabling precise solutions to the Schrödinger equation for interacting quantum systems. Despite…
Fragmented superconductivity in the Hubbard model as solitons in Ginzburg-Landau theory
Niccolò Baldelli, Hannes Karlsson, Benedikt Kloss +2
The phenomena of superconductivity and charge density waves are observed in close vicinity in many strongly correlated materials. Increasing evidence from experiments and numerical…
