Fermi surface topology and magneto-quantum oscillations for under-doped YBCO with hopping anisotropy
Partha Goswami
We investigate a chiral d-density wave (CDDW) mean field Hamiltonian in momentum space, which also includes the in-plane hopping anisotropy parameter e, for the under-doped YBCO to…

Optical absorption and emission of a quantum dot in the Kondo regime
Partha Goswami, Garima Puneyani, Avinashi Kapoor
A variant of the Anderson model, that describes hybridization between localized state (c-state) of a quantum dot and a Fermi sea conduction band, is investigated. We demonstrate th…

Theoretical Investigation of Fermion Pairings in Three-band Extended Hubbard Model
Partha Goswami
The two-dimensional d-p model (or extended Hubbard model) on a square lattice is investigated for fermion pairing by a slave boson method. The inter-site d-fermion interaction is i…
