TBHubbard: tight-binding and extended Hubbard model dataset for metal-organic frameworks [PDF]
Scientific DataMetal-organic frameworks (MOFs) are porous materials composed of metal ions and organic linkers. Due to their chemical diversity, MOFs can support a broad range of applications in chemical separations.

Stripe Orders in the Extended Hubbard Model [PDF]
Journal of the Physical Society of Japan, 2000 We study stripe orders of charge and spin density waves in the extended Hubbard model with the nearest-neighbor Coulomb repulsion V within the mean field approximation. We obtain V vs. T(temperature) phase diagram for the on-site Coulomb interaction U/t=8.0 and the filling n=0.8, here t is a nearest-neighbor transfer energy.

Investigation of enhanced thermoelectric response in the extended Lieb lattice using the Hubbard model [PDF]
Scientific ReportsWe investigate the thermoelectric properties of the extended Lieb lattice under the influence of intrinsic spin-orbit coupling, on-site Coulomb interaction, and an external magnetic field using the Hubbard model and linear response theory.

Density-dependent tunneling in the extended Bose–Hubbard model
New Journal of Physics, 2013 Recently, it has become apparent that when the interactions between polar molecules in optical lattices become strong, the conventional description using the extended Hubbard model has to be modified by additional terms, in particular a density-dependent

Maximally Localized Wannier Orbitals and the Extended Hubbard Model for Twisted Bilayer Graphene
Physical Review X, 2018 We develop an effective extended Hubbard model to describe the low-energy electronic properties of the twisted bilayer graphene. By using the Bloch states in the effective continuum model and with the aid of the maximally localized algorithm, we ...

Expanded Heisenberg Hamiltonians from a Mn/Bi DFT+U study on hexagonal antiferromagnet CaMn2Bi2: excitations and strain-controlled magnetic anisotropy switching [PDF]
Scientific ReportsThe manganese pnictide CaMn $$_2$$ Bi $$_2$$ exhibits narrow-gap antiferromagnetism with Mn atoms arranged in a puckered honeycomb structure, and is currently a promising candidate for ultra-fast light control of AFM states.

Symmetries of an extended Hubbard Model [PDF]
Banach Center Publications, 1997 An extended Hubbard model with phonons is considered on a D-dimensional lattice. The symmetries of the model are studied in various cases. It is shown that for a certain choice of the parameters a superconducting SU_q(2) holds as a true quantum symmetry - but only for D=1.

Pairing symmetries in the Zeeman-coupled extended attractive Hubbard model
Scientific Reports, 2021 By introducing the possibility of equal- and opposite-spin pairings concurrently, we show that the ground state of the extended attractive Hubbard model (EAHM) exhibits rich phase diagrams with a variety of singlet, triplet, and mixed parity ...

Traces of electron-phonon coupling in one-dimensional cuprates
Nature Communications, 2023 The appearance of certain spectral features in one-dimensional (1D) cuprate materials has been attributed to a strong, extended attractive coupling between electrons.
