Emerging giant resonant exciton induced by Ta-substitution in anatase TiO: a tunable correlation effect
Z. Yong, P. E. Trevisanutto, L. Chiodo +11
Titanium dioxide (TiO) has rich physical properties with potential implications in both fundamental physics and new applications. Up-to-date, the main focus of applied research…
Assessment of the TCA functional in computational chemistry and solid-state physics
E. Fabiano, L. A. Constantin, A. Terentjevs +2
We assess the Tognetti-Cortona-Adamo (TCA) generalized gradient approximation correlation functional [J. Chem. Phys. 128:034101 (2008)] for a variety of electronic systems. We find…
Optical conductivity renormalization of graphene on SrTiO due to resonant excitonic effects mediated by Ti 3\textit{d} orbitals
Pranjal Kumar Gogoi, Paolo E. Trevisanutto, Ming Yang +10
We present evidence of a drastic renormalization of the optical conductivity of graphene on SrTiO resulting in almost full transparency in the ultraviolet region. These finding…
Generalized gradient approximation correlation energy functionals based on the uniform electron gas with gap model
E. Fabiano, P. E. Trevisanutto, A. Terentjevs +1
We study the uniform electron gas with a gap model in the context of density functional theory. Based on this analysis, we construct two local gap models that realize generalized g…
LDA+U and tight-binding electronic structure of InN nanowires
A. Molina-Sánchez, A. García-Cristóbal, A. Cantarero +2
In this paper we employ a combined {\it ab initio} and tight-binding approach to obtain the electronic and optical properties of hydrogenated InN nanowires. We first discuss InN ba…
Optical spectra of solids obtained by time-dependent density-functional theory with the jellium-with-gap model exchange-correlation kernel
Paolo E. Trevisanutto, Aleksandrs Terentjevs, Lucian A. Constantin +2
Within the framework of ab initio time-dependent density-functional theory (TD-DFT), we propose a static approximation to the exchange-correlation kernel based on the jellium-with-…
