Theory of ab initio downfolding with arbitrary range electron-phonon coupling
Norm M. Tubman, Christopher J. N. Coveney, Chih-En Hsu +6
Ab initio downfolding describes the electronic structure of materials within a low-energy subspace, often around the Fermi level. Typically starting from mean-field calculations, t…

Ultrafast Spontaneous Exciton Dissociation via Phonon Emission in BiVO
Stephen E. Gant, Antonios M. Alvertis, Christopher J. N. Coveney +3
Monoclinic bismuth vanadate (m-BiVO) is a promising indirect band gap semiconductor for photoelectrochemical water splitting, yet the characteristics of its low-lying photoexci…

Phonon-mediated electron attraction in SrTiO via the generalized Fröhlich and deformation potential mechanisms
Christopher J. N. Coveney, Norm M. Tubman, Chih-En Hsu +6
Superconductivity in doped SrTiO was discovered in 1964, the first superconducting transition observed in a doped semiconductor. However, the mechanism of electron pairing in S…
