Oxygen on-site Coulomb energy in PrLaCeCuO and BiSrCaCuO and its relation with Heisenberg exchange
A. Chainani, M. Horio, C. -M. Cheng +20
We study the electronic structure of electron-doped PrLaCeCuO (PLCCO ; = 27 K, x = 0.1) and hole-doped BiSrCaCuO (Bi2212 ;…
Connecting the one-band and three-band Hubbard models of cuprates via spectroscopy and scattering experiments
K. Sheshadri, D. Malterre, A. Fujimori +1
The one-band and three-band Hubbard models which describe the electronic structure of cuprates indicate very different values of effective electronic parameters, such as the on-sit…
Unconventional Superfluidity in a model of Fermi-Bose Mixtures
K. Sheshadri, A. Chainani
A finite-temperature () study of a model of a mixture of spin-zero hardcore bosons and spinless fermions, with filling fractions and , respectively, on a two-dimens…
Coupled First-Order Transitions In A Fermi-Bose Mixture
K. Sheshadri, A. Chainani
A model of a mixture of spinless fermions and spin-zero hardcore bosons, with filling fractions and , respectively, on a two-dimensional square lattice with {\em composi…
Frustration effects and role of selective exchange coupling for magnetic ordering in the Cairo pentagonal lattice
A. Chainani, K. Sheshadri
The Cairo pentagonal lattice, consisting of an irregular pentagonal tiling of magnetic ions on two inequivalent sites (3- and 4-co-ordinated ones), represents a fascinating example…
Bose-Hubbard Models in Confining Potentials: An Inhomogeneous Mean-Field Theory
Ramesh V. Pai, Jamshid Moradi Kurdestany, K. Sheshadri +1
We present an extensive study of Mott insulator (MI) and superfluid (SF) shells in Bose-Hubbard (BH) models for bosons in optical lattices with harmonic traps. For this we develop…
