Such a RDB soliton has a ring-shaped notch (zero in density) imprinted on a 2D bright soliton free to move in the x - z plane. At medium velocity the head-on collision of two such solitons is found to be quasi-elastic with practically no deformation. The possibility of creating the RDB soliton by phase imprinting is demonstrated. The findings are illustrated using numerical simulation employing realistic interaction parameters in a dipolar 164Dy BEC.engBoseEinstein condensationdipolar atomssolitonArtigo10.1088/1612-2011/13/3/035502Acesso aberto2-s2.0-849748153782-s2.0-84974815378.pdf
