Disorder-induced localisation in the Mott-Hubbard model
RiÄards Kristers KnipÅ¡is, Friedemann Queisser, Jesumony Jayabalan +4
For the Fermi-Hubbard model in the Mott insulator phase, we employ the hierarchy of correlations to study how doublon and holon quasi-particle excitations are affected by adding di…

Direct signatures of -level hybridization and dimerization in magnetic adatom chains on a superconductor
Lisa M. Rütten, Eva Liebhaber, Gael Reecht +2
Magnetic adatom chains on superconductors provide a platform to explore correlated spin states and emergent quantum phases. Using low-temperature scanning tunneling spectroscopy, w…
