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…
On Nernst effect and quantum oscillations in NCCO
Partha Goswami
We start with a mean field Hamiltonian in momentum space for NCCO to investigate the magnetic quantum oscillations (MQO) exhibited by this system in the normal state. We first obta…
Theoretical investigation of a CDDW Hamiltonian for YBCO to explore the possibility of quantum oscillations in specific heat
Partha Goswami
We investigate a chiral d-density wave (CDDW) mean field Hamiltonian in momentum space for the under-doped YBCO. We consider the commensurate density wave order which doubles the u…
Investigation of chiral density wave mean field Hamiltonian
Partha Goswami
We start with the chiral density wave(CDW)mean field Hamiltonian in the momentum space for the pseudo-gapped state of YBCO in the absence of magnetic field, including the momentum…
Theoretical investigation of pseudo-gap state of YBCO
Partha Goswami
A momentum space, mean field d-density wave (DDW) Hamiltonian is investigated self-consistently. The pseudo-gapped(PG)state of YBCO is assumed to correspond to the pure DDW state.…
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…
