Stochastic binary networks with asymmetric and time-delayed interactions
Hantao Zhang, Sidra Gibeault, Matthew W. Daniels +4
Stochastic binary networks are widely used to describe collective dynamics in complex systems and to perform neuromorphic computation, yet realistic networks often contain both asy…
Quantum Spin Transfer of Spin-Correlated Electron Pairs
Seongmun Hwang, Jung Hyun Oh, Paul M. Haney +2
We theoretically investigate quantum spin transfer from spin-correlated conduction-electron pairs to localized spins in a ferromagnet, given that electrons are correlated intrinsic…
Electric Field-Induced Kerr Rotation on Metallic Surfaces
Farzad Mahfouzi, Mark D. Stiles, Paul M. Haney
We use a combination of density functional theory calculations and optical modeling to establish that the electric field-induced Kerr rotation in metallic thin films has contributi…
Strain effects on the fluctuation properties in noncollinear antiferromagnets: a first-principles and macrospin-based study
Mohammad M. Rahman, Farzad Mahfouzi, Matthew W. Daniels +1
We present a theoretical investigation of epitaxial strain effects on the magnetic fluctuation properties of MnSn noncollinear antiferromagnets. Employing density functional th…
Sampling from exponential distributions in the time domain with superparamagnetic tunnel junctions
Temitayo N. Adeyeye, Sidra Gibeault, Daniel P. Lathrop +8
In the superparamagnetic regime, magnetic tunnel junctions switch between two resistance states due to random thermal fluctuations. The dwell time distribution in each state is exp…
