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…
