Square Net TaSiAs Nanowires with Topological Surface Conduction and Linear Magnetoresistance
Anand Roy, Ofek Goldreich, Guy Ohad +7
Square-net topological materials exhibit various interesting properties arising from the interplay of their structural diversity, topologically protected bands and different possib…
Automated Workflow for Non-Empirical Wannier-Localized Optimal Tuning of Range-Separated Hybrid Functionals
Stephen E. Gant, Francesco Ricci, Guy Ohad +3
We introduce an automated workflow for generating non-empirical Wannier-localized optimally-tuned screened range-separated hybrid (WOT-SRSH) functionals. WOT-SRSH functionals have…
Foundations of the ionization potential condition for localized electron removal in density functional theory
Guy Ohad, MarÃa Camarasa-Gómez, Jeffrey B. Neaton +3
Optimal tuning of functional parameters in density functional theory approximations, based on enforcing the ionization potential theorem, has emerged as the method of choice for th…
Resolving Contradictory Estimates of Band Gaps of Bulk PdSe: A Wannier-Localized Optimally-Tuned Screened Range-Separated Hybrid Density Functional Theory Study
Fred Florio, MarÃa Camarasa-Gómez, Guy Ohad +3
Palladium diselenide (PdSe) -- a layered van der Waals material -- is attracting significant attention for optoelectronics due to the wide tunability of its band gap from the i…
