Kinks and solitons in SUSY models

Journal of Physics A: Mathematical and General, 1990
The authors consider arbitrary two-dimensional supersymmetric theories including kinks or solitons solutions. Going to sine-Gordon and ( lambda phi 4)1+1 theories, they compute the first quantum correction to the classical mass using a technique which only needs the discrete levels of Schrodinger equations.

Kink solitons in quadratic-cubic nonlinear dispersive media

Physical Review E, 1994
We show analytically that the coexistence of quadratic and cubic nonlinearities in dispersive media offers kink solitons with the Fermi-Dirac distribution. The underlying principle and the ubiquity of the present solitons are discussed.

KINKS AND SOLITONS IN THE GENERALISED GINSBURG-LANDAU EQUATION

Optical Solitons, 1990
The present paper is devoted to the study of localized patterns in models in which a trivial homogeneous state is stable against infinitesimal disturbances, but can be triggered into a nontrivial oscillatory state by a finite disturbance. A well-Known example of a physical medium that demonstrates this property is a layer of a binary liquid heated from

Nonpropagating soliton and kink soliton in a mildly sloping channel

Physics of Fluids A: Fluid Dynamics, 1992
The nonlinear equation governing both the nonpropagating soliton and kink soliton in a channel with slowly varying depth of water has been derived using the perturbation method of multiple scales. Both nonpropagating soliton and kink soliton solutions for the special case of a mildly sloping channel have been given.

Verhakungen, dislocations, solitons, and kinks

International Journal of Materials Research, 2009
Abstract The paper retraces, from a personal viewpoint, the development of atomistic models of dislocations in crystals from the model of Prandtl, Dehlinger, Frenkel, and Kontorova, first conceived in 1912, to recent work on kinks in dislocations.

Comment on “kink solitons and friction”

Physics Letters A, 1986
Abstract Based on hamiltonian density for frictionless φ4 theory it is argued that a recently given “displaced kink soliton” by Lal for the φ4 equation with friction βφt has infinite energy and therefore seems to move lossless. Analyzing the energy loss one finds the velocity υ = υ(β) in agreement with Lal.

Kinks and Solitons in Coupled Pendulum Lattices

Chinese Physics Letters, 1992
Self-localized structures in nonlinear coupled pendulum lattices are investigated by use of the method of multiple-scales under quasi-discreteness approximation. The upper cutoff and noncutoff kinks observed by Denardo et al. recently are theoretically explained qualitatively and a lower cutoff standing soliton is also predicated.

Kink-Solitons in Quantum-Dot Cellular Automata

Japanese Journal of Applied Physics, 2001
We examine the propagation of electric polarization in quantum-dot cellular automata (QCA) as a kink-soliton. We solve the time-dependent Schrödinger equation numerically by the Hartree approximation and also by the exact method. By the Hartree approximation, we find that the shape of the kink-soliton can be fitted very well to a function of ...

Demonstration Systems for Kink-Solitons

2007
We consider a mechanical lattice where the basic oscillating units experience a double-well on-site potential, and are linearly and nonlinearly coupled. In the continuum limit the lattice equations can be approximated by a nonlinear partial differential equation. With nonlinear coupling only, this equation exhibits a static kink solution with a compact
