Spin excitations in a 4f-3d heterodimer on MgO
A. Singha, F. Donati, F. D. Natterer +6
We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic transition metal-lanthanide compound. The dimers are adsorbed on ultrathin MgO(…
Nuclear Tunnelling and Dynamical Jahn-Teller Effect in Graphene with Vacancy
Z. S. Popović, B. R. K. Nanda, S. Satpathy
We show that the substitutional vacancy in graphene forms a dynamical Jahn-Teller center. The adiabatic potential surface resulting from the electron-lattice coupling was computed…
Electronic structure of the substitutional vacancy in graphene: Density-functional and Green's function studies
B. R. K. Nanda, M. Sherafati, Z. Popović +1
We study the electronic structure of graphene with a single substitutional vacancy using a combination of the density-functional, tight-binding, and impurity Green's function appro…
Airy-function electron localization in the oxide superlattices
Z. S. Popovic, S. Satpathy
Oxide superlattices and microstructures hold the promise for creating a new class of devices with unprecedented functionalities. Density-functional studies of the recently fabricat…
