Theory of excited state absorptions in phenylene-based -conjugated polymers
Alok Shukla, Haranath Ghosh, S. Mazumdar
Within a rigid-band correlated electron model for oligomers of poly-(paraphenylene) (PPP) and poly-(paraphenylenevinylene) (PPV), we show that there exist two fundamentally differe…
Coexistence of Band Jahn Teller Distortion and superconductivity in correlated systems
Haranath Ghosh, Manidipa Mitra, S. N. Behera +1
The co-existence of band Jahn-Teller (BJT) effect with superconductivity (SC) is studied for correlated systems, with orbitally degenerate bands using a simple model. The Hubbard m…
Effect of electron corelation on superconducting pairing symmetry
Manidipa Mitra, Haranath Ghosh, S. N. Behera
The role of electron correlation on different pairing symmetries are discussed in details where the electron correlation has been treated within the slave boson formalism. It is sh…
Raman scattering in high temperature superconductors : An integrated view
S. N. Behera, Umesh. A. Salian, Haranath Ghosh
The common features in the Raman data of high temperature superconductors: (the cuprates, bismathates, alkali doped fullerides and some organic superconductors), are analyzed. It w…
Raman continuum in high- superconductors
Haranath Ghosh, Manas Sardar
Experimentally, Raman continuum for and geometry exhibits peaks far apart from each other (about 80 to 150 ) in frequency. The former is insensitive to dop…
Enhancement of superconducting correlation due to interlayer tunneling.
Haranath Ghosh, M. Sardar
Interlayer single particle tunneling between the layers suppress the in-plane short range magnetic order (which is modeled as spin density wave (SDW) insulator). Doping over…
