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…
