Electrical control of the linear optical properties of particulate composite materials [PDF]

open access: yes, 2006
The Bruggeman formalism for the homogenization of particulate composite materials is used to predict the effective permittivity dyadic of a two-constituent composite material with one constituent having the ability to display the Pockels effect ...

Waveform control of orientation-dependent ionization of DCl in few-cycle laser fields [PDF]

open access: yes, 2011
Strong few-cycle light fields with stable electric field waveforms allow controlling electrons on time scales down to the attosecond domain. We have studied the dissociative ionization of randomly oriented DCl in 5 fs light fields at 720 nm in the ...
