Quantum Criticality in a Layered Iridate

Kousik Samanta, Jean C. Souza, Danilo Rigitano +3

Iridates provide a fertile ground to investigate correlated electrons in the presence of strong spin-orbit coupling. Bringing these systems to the proximity of a metal-insulator qu…

Anisotropic Lattice Compression and Pressure-Induced Electronic Phase Transitions in SrIrO

K. Samanta, R. Tartaglia, U. F. Kaneko +2

The crystal lattice of SrIrO is investigated with synchrotron X-ray powder diffraction under hydrostatic pressures up to GPa and temperatures down to K. The tet…

Isospin-phonon coupling and Fano-interference in spin-orbit Mott insulator Sr2IrO4

Kousik Samanta, Danilo Rigitano, Pascoal Jose Giglio Pagliuso +1

The isospin-phonon coupling in Sr2IrO4 is investigated by temperature dependent phonon Raman scattering. Anomalous behavior in the frequency of all studied optical phonons is obser…

First-order structural transition and pressure-induced lattice/phonon anomalies in SrIrO

K. Samanta, F. M. Ardito, N. M. Souza-Neto +1

We investigate the crystal structure and lattice vibrations of SrIrO by a combined phonon Raman scattering and x-ray powder diffraction experiment under pressures up to $66…

Projected Quasiparticle Theory for Molecular Electronic Structure

Gustavo E. Scuseria, Carlos A. Jimenez-Hoyos, Thomas M. Henderson +2

We derive and implement symmetry-projected Hartree-Fock-Bogoliubov (HFB) equations and apply them to the molecular electronic structure problem. All symmetries (particle number, sp…

The structural and magnetic properties of (In1-xFex)2O3 (0.0 <= x <= 0.25) system : prepared by gel combustion method

O. D. Jayakumar, I. K. Gopalakrishnan, S. K. Kulshreshtha +9

(In1-xFex)2O3 polycrystalline samples with x = (0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) have been synthesized by a gel combustion method. Reitveld refinement analysis of X raydiffrac…
