Twisted curve geometry underlying topological invariants
Radha Balakrishnan, Rossen Dandoloff, Avadh Saxena
Topological invariants such as winding numbers and linking numbers appear as charges of topological solitons in diverse nonlinear physical systems described by a unit vector field…
Exact Hopfion Vortices in a 3D Heisenberg Ferromagnet
Radha Balakrishnan, Rossen Dandoloff, Avadh Saxena
We find exact static soliton solutions for the unit spin vector field of an inhomogeneous, anisotropic three-dimensional Heisenberg ferromagnet. Each soliton is labeled by two inte…
Solitons in a hard-core bosonic system: Gross-Pitaevskii type and beyond
Radha Balakrishnan, Indubala I Satija
A unified formulation that obtains solitary waves for various background densities in the Bose-Einstein condensate of a system of hard-core bosons with nearest neighbor attractive…
Quantum Dynamics of Solitons in Strongly Interacting Systems on Optical Lattices
Chester P. Rubbo, Indubala I. Satija, William P. Reinhardt +3
Mean-field dynamics of strongly interacting bosons described by hard core bosons with nearest-neighbor attraction has been shown to support two species of solitons: one of Gross-Pi…
Other incarnations of the Gross-Pitaevskii dark soliton
Indubala I Satija, Radha Balakrishnan
We show that the dark soliton of the Gross-Pitaevskii equation (GPE) that describes the Bose-Einstein condensate (BEC) density of a system of weakly repulsive bosons, also describe…
The Gross-Pitaevskii Soliton: Relating Weakly and Strongly Repulsive Bosonic condensates and the magnetic soliton
Indubala I Satija, Radha Balakrishnan
We show that the dark soliton of the Gross-Pitaevskii equation (GPE) that describes the Bose-Einstein condensate (BEC) density of a system of weakly repulsive bosons, also describe…
