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…
Kohn-Sham Kinetic Energy Density in the Nuclear and Asymptotic Regions: Deviations from the Von Weizsäcker Behavior and Applications to Density Functionals
F. Della Sala, E. Fabiano, L. A. Constantin
We show that the Kohn-Sham positive-definite kinetic energy (KE) density significantly differs from the von Weizsäcker (VW) one at the nuclear cusp as well as in the asymptotic reg…
Gradient-dependent upper bound for the exchange-correlation energy and application to density functional theory
L. A. Constantin, E. Fabiano, A. Terentjevs +1
We propose a simple gradient-dependent bound for the exchange-correlation energy (sLL), based on the recent non-local bound derived by Lewin and Lieb. We show that sLL is equivalen…
Graphene-based absorber exploiting guided mode resonances in one-dimensional gratings
M. Grande, M. A. Vincenti, T. Stomeo +8
A one-dimensional dielectric grating, based on a simple geometry, is proposed and investigated to enhance light absorption in a monolayer graphene exploiting guided mode resonances…
Ultrafast control of Rabi oscillations in a polariton condensate
L. Dominici, D. Colas, S. Donati +10
We report the experimental observation and control of space and time-resolved light-matter Rabi oscillations in a microcavity. Our setup precision and the system coherence are so h…
Orbital-dependent second-order scaled-opposite-spin correlation functionals in the optimized effective potential method
I. Grabowski, E. Fabiano, A. Teale +3
The performance of correlated optimized effective potential (OEP) functionals based on the spin-resolved second-order correlation energy is analyzed. The relative importance of sin…
