Two-dimensional Keldysh theory for non-resonant strong-field ionization of monolayer 2D materials
Tsing-Hua Her, Che-Hao Chang, Kenan Darden +2
The Keldysh theory of photoionization for solids is generalized to atomically thin two-dimensional semiconductors. We derive a closed-form formula and its asymptotic forms for a tw…

Frequency-induced Negative Magnetic Susceptibility in Epoxy/Magnetite Nanocomposites
Che-Hao Chang, Shih-Chieh Su, Tsun-Hsu Chang +1
The epoxy/magnetite nanocomposites express superparamagnetism under a static or low-frequency electromagnetic field. At the microwave frequency, said the X-band, the nanocomposites…
