Heavy-hole spin relaxation in quantum dots: Isotropic versus anisotropic effects
Dalton Forbes, Sanjay Prabhakar, Ruma De +2
Non-charge based logic in single-hole spin of semiconductor quantum dots (QDs) can be controlled by anisotropic gate potentials providing a notion for making next generation solid-…
Ultrafast nonadiabatic electron dynamics in photoexcited C60: A comparative study among DFT exchange-correlation functionals
Esam Ali, Mohamed El-Amine Madjet, Ruma De +2
The non-radiative electron-relaxation dynamics in C molecule is studied after selective initial photoexcitations. The methodology includes nonadibabtic molecular simulation…
Density functional study of the variants of inter-Coulombic decay resonances in the photoionization of Cl@C60
Ruma De, Esam Ali, Steven T. Manson +1
Inter-Coulombic decay (ICD) resonances in the photoionization of Cl@C60 endofullerene molecule are calculated using a perturbative density functional theory (DFT) method. This is t…

First prediction of inter-Coulombic decay of C60 inner vacancies through the continuum of confined atoms
Ruma De, Maia Magrakvelidze, Mohamed E Madjet +2
Considering the photoionization of Ar@C60 and Kr@C60 endofullerenes, the decay of C60 innershell excitations through the outershell continuum of the confined atom via the inter-Cou…
Coherence of Auger and inter-Coulombic decay processes in the photoionization of Ar@C60 versus Kr@C60
Maia Magrakvelidze, Ruma De, Mohammad H. Javani +3
For the asymmetric spherical dimer of an endohedrally confined atom and a host fullerene, an innershell vacancy of either system can decay through the continuum of an outer electro…
Photoionization of bonding and antibonding-type atom-fullerene hybrid states in Cd@C vs Zn@C60
Mohammad H. Javani, Ruma De, Mohamed E. Madjet +2
Powerful hybridization of the Cd 4 state with the -angular momentum state of C symmetry is found in the local density approximation (LDA) structure of Cd@C…
Resonant Auger-intercoulombic hybridized decay in the photoionization of endohedral fullerenes
Mohammad H. Javani, Jacob B. Wise, Ruma De +3
Considering the photoionization of Ar@C60, we predict resonant femtosecond decays of both Ar and C60 vacancies through the continua of atom-fullerene hybrid final states. The resul…
