Hermite–Gaussian solitons in 1+2 dimensional nonlocal nonlinear systems with Y0-oscillatory response

AIP Advances
We investigate the Hermite–Gaussian solitons in 1+2 dimensional nonlocal nonlinear systems with Y0-oscillatory response. The iterative solution of the solitons is numerically found using the accelerated imaginary-time evolution method with amplitude ...

Spontaneous symmetry breaking for solitons and local meta-stability: an elliptic functions based formulation

European Physical Journal C: Particles and Fields
We show that in an elliptic function based formulation for fields with large amplitudes, the rolling down of solitons towards the degenerate vacua can be described as transitions through local meta-stable potentials; the kink-like solitons constructed ...

Discrete solitons in optical BEC lattices. Effects of n-body interactions [PDF]

, 2006
In this poster we show some recent results concerning discrete solitons in strong optical lattices, which can be described by the Discrete Nonlinear Schrödinger equation.

Hyperbolic conformal Ricci solitons and gradient hyperbolic conformal Ricci solitons on bulk viscous fluid string spacetime

European Physical Journal C: Particles and Fields
We explore the Geometrization of hyperbolic conformal Ricci solitons and examine the properties of bulk viscous fluid string spacetime in conjunction with the hyperbolic conformal Ricci solitons in this research note. A $$\varnothing ({\mathfrak {Q}})$$ ∅

Affine Toda solitons and fusing rules [PDF]

, 1994
This thesis is concerned with various soliton solutions to some of the affine Toda field theories. These are field theories in 1+1 dimensions that possess a rich underlying Lie algebraic structure and they are known to be integrable.

The complex sine-Gordon model on a half line [PDF]

, 2003
In this thesis, we study the complex sine-Gordon model on a half line. The model in the bulk is an integrable (l+1) dimensional field theory which is U(1) gauge invariant and comprises a generalisation of the sine-Gordon theory.
