Raman Signatures of Strong Kitaev Exchange Correlations in (NaLi)IrO : Experiments and Theory
Satyendra Nath Gupta, P. V. Sriluckshmy, Kavita Mehlawat +7
Inelastic light scattering studies on single crystals of (NaLi)IrO ( and ) show a polarization independent broad band at ~2750 cm$^{-1…
Novel effects of localization due to `intrinsic disorder' in the `two-fluid' model for manganites
Prabuddha Sanyal, V. B. Shenoy, H. R. Krishnamurthy +1
We discuss the effects of a novel polaronic disorder in the recently proposed two-fluid model for manganites. Using effective field theory as well as direct numerical simulations,…
Pairing Fluctuations Determine Low Energy Electronic Spectra in Cuprate Superconductors
Sumilan Banerjee, T V Ramakrishnan, C Dasgupta
We describe here a minimal theory of tight binding electrons moving on the square planar Cu lattice of the hole-doped cuprates and mixed quantum mechanically with pairs of them (Co…
Long Range Coulomb Interactions and Nanoscale Electronic Inhomogeneities in Correlated Oxides
Vijay B. Shenoy, Tribikram Gupta, H. R. Krishnamurthy +1
Electronic, magnetic or structural inhomogeneities ranging in size from nanoscopic to mesoscopic scales seem endemic, and are possibly generic, to colossal magnetoresistance mangan…
Unusual doping and temperature dependence of photoemission spectra from manganites
Prabuddha Sanyal, Subhra Sen Gupta, Nandan Pakhira +3
A recent, major, puzzle in the core-level photoemission spectra of doped manganites is the observation of a 1-2 eV wide shoulder with intensity varying with temperature T as the sq…
Coulomb Interactions and Nanoscale Electronic Inhomogeneities in Manganites
Vijay B. Shenoy, Tribikram Gupta, H. R. Krishnamurthy +1
We address the issue of endemic electronic inhomogeneities in manganites using extensive simulations on a new model with Coulomb interactions amongst two electronic fluids, one loc…
