Fermi pockets and quantum oscillations in specific heat of YBCO in the presence of disorder
Partha Goswami, Manju Rani, Avinashi Kapoor
We investigate a chiral d-density wave (CDDW) mean field model Hamiltonian in the momentum space suitable for the hole-doped cuprates, such as YBCO, in the pseudo-gap phase to obta…
Electronic viscosity in a multiple quantum well system
Partha Goswami, Ajay Pratap Singh Gahlot, Avinashi Kapoor
We calculate the electronic viscosity for a multiple quantum well structure in the presence of disorder potential(V = 4 meV), the electron-electron repulsion(U = 5-17 meV) and a st…
Investigation of confined electron gas in a quantum well structure with photovoltaic application
Partha Goswami, Garima Puneyani, Avinashi Kapoor
The growth-diection quantization of confined electron gas in a GaAs/AlGaAs based quantum well structure is obtained in the Kohn-Sham iterative computational scheme. The longitudina…
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…
