Mean-field theory of 1+1D lattice gauge theory with matter
Matjaž KebriÄ, Ulrich Schollwöck, Fabian Grusdt
Lattice gauge theories (LGTs) provide valuable insights into problems in strongly correlated many-body systems. Confinement which arises when matter is coupled to gauge fields is j…
Two-dopant origin of competing stripe and pair formation in Hubbard and - models
Tizian Blatz, Ulrich Schollwöck, Fabian Grusdt +1
Understanding the physics of the two-dimensional Hubbard model is widely believed to be a key step in achieving a full understanding of high- cuprate superconductors.…
Emergent spinon-holon Feshbach resonance in a doped Majumdar-Ghosh model
Simon M. Linsel, Ulrich Schollwöck, Annabelle Bohrdt +1
Experimental and numerical spectroscopy have revealed rich physics in antiferromagnets, in particular in frustrated and doped systems. The Majumdar-Ghosh (MG) model has an analytic…
Hund flat band in a frustrated spinel oxide
Dongjin Oh, Alexander Hampel, Joshua P. Wakefield +26
Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenom…
Phonon state tomography of electron correlation dynamics in optically excited solids
Mattia Moroder, Matteo Mitrano, Ulrich Schollwöck +2
We introduce phonon state tomography (PST) as a diagnostic probe of electron dynamics in solids whose phonons are optically excited by a laser pulse at initial time. Using a projec…
Superconductivity in the pressurized nickelate LaNiO in the vicinity of a BEC-BCS crossover
Henning Schlömer, Ulrich Schollwöck, Fabian Grusdt +1
Ever since the discovery of high-temperature superconductivity in cuprates, gaining microscopic insights into the nature of pairing in strongly correlated, repulsively interacting…
