A real-time TDDFT study of femtosecond laser driven monolayer NbSe2
Towfiq Ahmed, Jinkyoung Yoo, Rohit Prasankumar +1
High harmonic generation (HHG) spectra have the potential to show novel signatures of ordered phases in condensed matter. We studied the femtosecond laser-driven electronic respons…
First principles investigation of nanopore sequencing using variable voltage bias on graphene-based nanoribbons
Hannah L. McFarland, Towfiq Ahmed, Jian-Xin Zhu +2
In this study, we examine the mechanism of nanopore-based DNA sequencing using a voltage bias across a graphene nanoribbon. Using density functional theory and a non-equilibrium Gr…
Combining electronic structure and many-body theory with large data-bases: a method for predicting the nature of 4f states in Ce compounds
Heike. C. Herper, Towfiq. Ahmed, John. M. Wills +5
Here we present the first large scale investigation of electronic properties and correlated magnetism in Ce-based compounds accompanied by a systematic study of the electronic stru…
Graphene/MoS2 van der Waals Bilayer as the Anode Material for Next Generation Li-ion Battery: A First-Principles Investigation
Towfiq Ahmed, N. A. Modine, Jian-Xin Zhu
We performed density functional theory (DFT) calculations for a bi-layered heterostructure combining a graphene layer with a MoS2 layer with and without intercalated Li atoms. Our…
GW+U real-space Green's function calculations of x-ray spectra
Towfiq Ahmed, J. J. Kas, J. J. Rehr
The Hubbard model is implemented in real-space Green's function calculations of x-ray spectra using an effective self-energy adapted from the LSDA+U method of Anisimov et al. This…
