Non-Scissors-Mode Behaviour of Isovector Magnetic Dipole Orbital Transitions Involving Isospin Transfer
We study the response of isovector orbital magnetic dipole (IOMD) transitions to the quadrupole-quadrupole (Q · Q) interaction, to the isospinconserving pairing interaction (ICP) and to combinations of both. We find qualitatively different behaviours for transitions in which the final isospin differs from the initial isospin versus cases where the two isospins are the same. For N = Z even-even ...
متن کاملDipole-mode vector solitons
We find a new type of optical vector soliton that originates from trapping of a dipole mode by the soliton-induced waveguides. These solitons, which appear as a consequence of the vector nature of the two-component system, are more stable than the previously found optical vortex solitons and represent a new type of extremely robust nonlinear vector structure.
متن کاملCounterpropagating dipole-mode vector soliton.
We experimentally observed a counterpropagating dipole-mode vector soliton in a photorefractive SBN:60Ce crystal. We investigated the transient formation dynamics and show that the formation process differs significantly from the copropagating geometry. The experimental results are compared with fully anisotropic numerical simulations and show good qualitative agreement.
متن کاملMulticomponent dipole-mode spatial solitons.
We study (2+1) -dimensional multicomponent spatial vector solitons with a nontrivial topological structure of their constituents and demonstrate that these solitary waves exhibit a symmetry-breaking instability, provided their total topological charge is nonzero. We describe a novel type of stable multicomponent dipole-mode solitons with intriguing swinging dynamics.
متن کاملisovector GMO
How precisely can we determine the πNN coupling constant from the isovector GMO sum rule? Abstract The isovector GMO sum rule for zero energy forward πN scattering is critically studied to obtain the charged πNN coupling constant using the precise π − p and π − d scattering lengths deduced recently from pionic atom experiments. This direct determination leads to g
