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…
Inducement of Spin-pairing and Correlated Semi-metallic State in Mott-Hubbard Quantum Dot Array
Partha Goswami, Avinashi Kapoor
We model a quantum dot-array (with one electron per dot) comprising of two (or more than two) coupled dots by an extended Hubbard Hamiltonian to investigate the role played by the…
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…
Thermal and Quantum Fluctuations Induced Additional Gap in Single-particle Spectrum of d-p model
Partha Goswami
The possibility of thermal and quantum fluctuations induced attractive interaction leading to a pairing gap Δ_tq in the single-particle spectrum of d-p model in the limit of a larg…
