A possible explanation for the high superconducting Tc in bcc Ti at high pressure
Antonio Sanna, Camilla Pellegrini, Simone di Cataldo +2
Motivated by unexpected reports of a 26 K superconducting transition in elemental titanium at high pressure, we carry out an accurate ab-initio study of its properties to understan…
Coulomb interactions and conventional superconductivity: when going beyond the random phase approximation is essential
Camilla Pellegrini, Carl Kukkonen, Antonio Sanna
In ab initio calculations of superconducting properties, the Coulomb repulsion is accounted for at the GW level and is usually computed in RPA, which amounts to neglecting vertex c…
Towards high-throughput superconductor discovery via machine learning
Stephen R. Xie, Y. Quan, Ajinkya Hire +5
Even though superconductivity has been studied intensively for more than a century, the vast majority of superconductivity research today is carried out in nearly the same manner a…
Superconducting Chevrel phase PbMoS from first principles
Giovanni Marini, Antonio Sanna, Camilla Pellegrini +3
Chevrel ternary superconductors show an intriguing coexistence of molecular aspects, large electron-phonon and electron-electron correlations, which to some extent still impedes th…
Ab initio theory of plasmonic superconductivity within the Eliashberg and density-functional formalisms
A. Davydov, A. Sanna, C. Pellegrini +3
We extend the two leading methods for the \emph{ab initio} computational descrip tion of phonon-mediated superconductors, namely Eliashberg theory and density fu nctional theory fo…
Optimized Effective Potential for Quantum Electrodynamical Time-Dependent Density Functional Theory
Camilla Pellegrini, Johannes Flick, Ilya V. Tokatly +2
We propose a practical approximation to the exchange-correlation functional of (time-dependent) density functional theory for many-electron systems coupled to photons. The (time no…
Quantum Electrodynamical Density-Functional Theory: Bridging Quantum Optics and Electronic-Structure Theory
Michael Ruggenthaler, Johannes Flick, Camilla Pellegrini +3
In this work we give a comprehensive derivation of an exact and numerically feasible method to perform ab-initio calculations of quantum particles interacting with a quantized elec…
