Two-phonon pairing and superconductivity in
Antonio Santacesaria, Cristiano Muzzi, Maria Eleonora Temperini +3
We explore the possibility that the two-phonon pairing mechanism proposed by Ngai can explain superconductivity in doped strontium titanate (STO). The two-phonon deformation potent…
THz near-field nanoscopy employing coherent synchrotron radiation
Alexander Veber, Maria Eleonora Temperini, Ljiljana Puskar +1
We demonstrate that the coherent synchrotron radiation (CSR) can be used for the scattering type near-field scanning optical microscopy (s-SNOM). Using a commercially available s-S…
How orbitals and oxidation states determine apparent topographies in scanning tunneling microscopy: the case of fluorine on silver surfaces
Adrián Gómez Pueyo, Jazmín Aragón Sánchez, Ilya Degtev +11
We use density functional theory calculations to characterize the early stages of fluorination of silver's (100) and (110) surfaces. In the Ag(100) surface, the hollow site is the…
Anisotropic Rashba coupling to polar modes in KTaO3
Giulia Venditti, Maria Eleonora Temperini, Paolo Barone +2
Motivated by the discovery of superconductivity in KTaO3-based heterostructures, we study a pairing mechanism based on spin-orbit assisted coupling between the conduction electrons…
Generalized Rashba Electron-Phonon Coupling and Superconductivity in Strontium Titanate
Maria N. Gastiasoro, Maria Eleonora Temperini, Paolo Barone +1
SrTiO3 is known for its proximity to a ferroelectric phase and for showing an 'optimal' doping for superconductivity with a characteristic dome-like behaviour resembling systems cl…
Theory of superconductivity mediated by Rashba coupling in incipient ferroelectrics
Maria N. Gastiasoro, Maria Eleonora Temperini, Paolo Barone +1
Experimental evidence suggests that superconductivity in SrTiO is mediated by a soft transverse ferroelectric mode which, according to conventional theories, has negligible cou…
