Anharmonic multiphonon origin of the valence plasmon in SrTi1-xNbxO3
Caitlin S. Kengle, Samantha I. Rubeck, Melinda Rak +10
Doped SrTi1-xNbxO3 exhibits superconductivity and a mid-infrared optical response reminiscent of copper-oxide superconductors. Strangely, its plasma frequency, omega_p, increases b…
Quantum Melting in a Polariton Lattice
Alexander Edelman, Peter B. Littlewood
Inspired by the recent experimental observation of strongly coupled polaritons in a Moiré heterobilayer, we study a model of dipole-interacting excitons localized on sites of a lat…
Going Beyond the Cumulant Approximation: Power Series Correction to Single Particle Green's Function in Holstein System
Bipul Pandey, Peter B. Littlewood
In the context of a single electron two orbital Holstein system coupled to dispersionless bosons, we develop a general method to correct single particle Green's function using a po…
Exploring Metastable States in UO using Hybrid Functionals and Dynamical Mean Field Theory
Laura E. Ratcliff, Luigi Genovese, Hyowon Park +2
A detailed exploration of the -atomic orbital occupancy space for UO is performed using a first principles approach based on density functional theory (DFT), employing a ful…
Large isotropic negative thermal expansion above a structural quantum phase transition
Sahan U. Handunkanda, Erin B. Curry, Vladimir Voronov +5
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of ene…
Giant magnetoelectric effect in pure manganite-manganite heterostructures
Sanjukta Paul, Ravindra Pankaj, Sudhakar Yarlagadda +2
Obtaining strong magnetoelectric couplings in bulk materials and heterostructures is an ongoing challenge. We demonstrate that manganite heterostructures of the form ${\rm (Insulat…
