Identification and optimization of accurate spin models for Fermi-Hubbard ladders using matrix product states
Andoni Agirre, Thomas Frederiksen, Geza Giedke +1
Open-shell nanographenes offer a controlled setting to study correlated magnetism emerging from -electron systems. Here, we study non-bipartite Fermi-Hubbard ladders describing…
Controlled pairing symmetries in a Fermi-Hubbard ladder with band flattening
J. P. Mendonça, J. P. Mendonça, S. Biswas +8
Band flattening has been identified as key ingredient to correlation phenomena in Moiré materials and beyond. Here, we examine strongly repulsive fermions on a ladder -- a minimal…
Frustrated Bose ladder with extended range density-density interaction
Sourav Biswas, E. Rico, Tobias Grass
When hard-core bosons on a two-leg ladder get frustrated by ring exchange interactions, the elusive d-wave Bose liquid (DBL) can be stabilized, a bosonic analog of a correlated met…
Ring-exchange physics in a chain of three-level ions
Sourav Biswas, E. Rico, Tobias Grass
In the presence of ring exchange interactions, bosons in a ladder-like lattice may form the bosonic analogon of a correlated metal, known as the d-wave Bose liquid (DBL). In this p…
