A Fractional-Order Infectivity SIR Model
Christopher N Angstmann, Bruce I Henry, Anna V McGann
Fractional-order SIR models have become increasingly popular in the literature in recent years, however unlike the standard SIR model, they often lack a derivation from an underlyi…
Anomalous dynamic behaviour of optically trapped high aspect ratio nanowires
Wen Jun Toe, Ignacio O. Piwonka, Christopher Angstmann +5
We investigate the dynamics of high aspect ratio nanowires trapped axially in a single gradient force optical tweezers. A power spectrum analysis of the Brownian dynamics reveals a…
A fractional order recovery SIR model from a stochastic process
C. N. Angstmann, B. I. Henry, A. V. McGann
Over the past several decades there has been a proliferation of epidemiological models with ordinary derivatives replaced by fractional derivatives in an an-hoc manner. These model…
Precision isotope shift measurements in Ca using highly sensitive detection schemes
Florian Gebert, Yong Wan, Fabian Wolf +3
We demonstrate an efficient high-precision optical spectroscopy technique for single trapped ions with non-closed transitions. In a double-shelving technique, the absorption of a s…
