Second-harmonic generation in the system with fractional diffraction
Pengfei Li, Hidetsugu Sakaguchi, Liangwei Zeng +3
We construct a family of bright optical solitons composed of fundamental frequency (FF) and second-harmonic (SH) components in the one-dimensional (planar) waveguide with the quadr…
One- and two-dimensional solitons in spin-orbit-coupled Bose-Einstein condensates with fractional kinetic energy
Hidetsugu Sakaguchi, Boris A. Malomed
We address effects of spin-orbit coupling (SOC), phenomenologically added to a two-component Bose-Einstein condensate composed of particles moving by Levy flights, in one- and two-…
Dragging spin-orbit-coupled solitons by a moving optical lattice
Hidetsugu Sakaguchi, Fumihide Hirano, Boris A. Malomed
It is known that the interplay of the spin-orbit-coupling (SOC) and mean-field self-attraction creates stable two-dimensional (2D) solitons (ground states) in spinor Bose-Einstein…
Damping of macroscopic oscillation and interference pattern in coupled Gross-Pitaevskii equations without self-interaction
Hidetsugu Sakaguchi, Fumihide Hirano
Quantum phenomena appear in a macroscopic scale in Bose-Einstein condensates. The Gross-Pitaevskii (GP) equation describes the dynamics of the weakly interacting Bose-Einstein cond…
Slow decay of infection in the inhomogeneous SIR model
Hidetsugu Sakaguchi, Yuta Nakao
The SIR model with spatially inhomogeneous infection rate is studied with numerical simulations in one, two, and three dimensions, considering the case that the infection spreads i…
Star shaped patterns caused by colloidal aggregation during the spreading process of a droplet
Michiko Shimokawa, Hiroyuki Kitahata, Hidetsugu Sakaguchi
This research found that when an acidic solution with a low surface tension spread on the surface of a glycerol solution mixed with milk, a star shaped pattern was spontaneously fo…
