Kinetic magnetism and stripe order in the antiferromagnetic bosonic model
Timothy J. Harris, Ulrich Schollwöck, Annabelle Bohrdt +1
Unraveling the microscopic mechanisms governing the physics of doped quantum magnets is key to advancing our understanding of strongly correlated quantum matter. Quantum simulation…
LiV2O4: Hund-Assisted Orbital-Selective Mottness
Martin Grundner, Fabian B. Kugler, Olivier Parcollet +3
We show that the remarkably small Fermi-liquid coherence scale and large effective mass observed in LiVO are due to the proximity of a Hund-assisted orbital-selective Mott…
Probing a Modified Luttinger Sum Rule in the Strongly Interacting 1D Fermi-Hubbard Model
Annika Böhler, Henning Schlömer, Ulrich Schollwöck +2
Fermi surface reconstruction in cuprates can lead to an abrupt change in the Fermi momentum between different phases. This phenomenon remains subject of debate and is at the…
