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 la…
Normal State Correlates of Plasmon-Polaron Superconductivity in Strontium Titanate
Alexander Edelman, Peter B Littlewood
We analyze a minimal model of SrTiO3, such as has been historically used to analyze the superconducting state. Treating the electron-phonon and electron-electron interactions on an…
Superconductivity in the dilute single band limit in reduced Strontium Titanate
Terence M. Bretz-Sullivan, Alexander Edelman, J. S. Jiang +9
We report on superconductivity in single crystals of SrTiO with carrier densities , where only a single band is occupied. For all sa…
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…
Non-Hermitian phase transition from a polariton Bose-Einstein condensate to a photon laser
Ryo Hanai, Alexander Edelman, Yoji Ohashi +1
We propose a novel mechanism for a nonequilibrium phase transition in a -broken phase of an electron-hole-photon system, from a Bose-Einstein condensate of polaritons to a ph…
