Possible signature of broken symmetry state near the quantum critical point in P doped BaFeAs: A Raman spectroscopy study
Debasmita Swain, Soumyadeep Ghosh, K. Bera +4
We study the iron-pnictide compound BaFe(AsP) for x 0.23, with a doping concentration near quantum criticality and enhanced nematic fluctuating state in t…
Stability of the doped antiferromagnetic state of the t-t'-Hubbard model
Avinash Singh, Haranath Ghosh
The next-nearest-neighbour hopping term t' is shown to stabilize the AF state of the doped Hubbard model with respect to transverse perturbations in the order- parameter by strongl…
Electron correlation induced transverse delocalization and longitudinal confinement in excited states of phenyl-substituted polyacetylenes
Haranath Ghosh, Alok Shukla, Sumit Mazumdar
Electron-electron interactions in general lead to both ground state and excited state confinement. We show, however, that in phenyl-substituted polyacetylenes electron-electron int…
Ultrafast optical nonlinearity in quasi-one-dimensional Mott-insulator
T. Ogasawara, M. Ashida, N. Motoyama +7
We report strong instantaneous photoinduced absorption (PA) in the quasi-one-dimensional Mott insulator in the IR spectral region. The observed PA is to an even-p…
Time reversal symmetry breaking superconductivity
Haranath Ghosh
We study time reversal symmetry breaking superconductivity with ( or ) symmetries. It is shown that the behavior of such supercond…
