Two-phonon pairing and superconductivity in
Antonio Santacesaria, Cristiano Muzzi, Maria Eleonora Temperini +4
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, JazmÃn 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…
