Quantum Dynamics and Elementary Excitations in Superfluid He4 Films at Low Temperatures
Vladimir I. Kruglov, Houria Triki
We have formulated a novel quantum nonlinear Schrodinger equation describing of superfluid He4 in films at low temperatures. It is shown that in classical limit the found nonlinear…

Pulse-train propagation in nonlinear Kerr media governed by higher-order dispersion
Houria Triki, Vladimir I. Kruglov
We discover three novel classes of pulse-train waveforms in an optical Kerr nonlinear medium possessing all orders of dispersion up to the fourth order. We show that both single- a…
