The existence and stability of multipeaked solitons are investigated in a parity-time symmetric superlattice with dual periods under both self-focusing and self-defocusing nonlinearity. For self-defocusing nonlinearit...
GaAs (001) substrates are patterned by electron beam lithography and wet chemical etching to control the nucleation of lnAs quantum dots (QDs). InAs dots are grown on the stripe-patterned substrates by solid sourc...
We have determined the drift of the fundamental frequency in the Lorenz model from a large amount of power spectra.This opens the possibility to devise an"absolute"nomenclature for various periods seen in the bifurcat...
