Lump soliton: a stable, 3D wave packet of light that maintains its shape even after colliding with other waves

"only observed in 1D before... waves distort/ lose information due to turbulence, overcome applying external voltage to strontium-barium niobate crystals, making solitons integrable in 3D space possessing conserved energy/ momentum keeping them stable, turned crystal's interior into photon fluid enabling light movement control through it, generating light beam matching mathematical lump... wave packet did not spread out/ distort as traveled, 2 lump solitons colliding through each other left properties/ shapes intact"
