And 3000*3000 without rendering the sine-Gordon equation as well as the B acklund Transformation and how our pendula system is used to demonstrate soliton solutions to the sine-Gordon. We also mention applications of this system to physics, including Lorentz invariance. Keywords: sine-Gordon, solitons, Backlund transform 1 Introduction Sine-Gordon equation Korteweg-de Vries equation ABSTRACT. The equation φ tt − φ xx + m 2 sin φ = 0 is presented as a model field theory and studied in 2020-04-14 · The sine-Gordon equation is a traditional wave equation with a sine function term. This equation and its modifications are widely applied in physics and engineering. It used to describe the spread of crystal defects, the propagation of waves, the extension of biological membranes, relativistic field theory, 1 – 3 it can reduce to the Klein–Gordon equation 4 , 5 in some special cases.

As The sine-Gordon equation has conserved quantity E1=12π∫−∞+∞φxdx which equals integer number.

Using this technique, we derive an equation for kink solutions, which is a travelling wave. We also derive a formula for breather solutions, which behave as wave 

Picture. Soliton is a kink which changes the Josephson phase from 0 to 2π (soliton) or from 2π to 0 (anti-soliton). The field of soliton is h = φ x = 2 cosh(√x−ut 1−u2),h| x=0 =2 The sine-Gordon equation is the Euler–Lagrange equation for this Lagrangian.

The nonlinear sine-Gordon equation (SGE), a type of hyperbolic partial differential equation, is often used to describe and simulate the physical phenomena in a variety of fields of engineering and science, such as nonlinear waves, propagation of fluxons and dislocation of metals [ 1 – 4 ].

in 1965, Gordon Moore conducted a survey of the trends in the field and predicted that the A library of first order static device equations for short channel MOSFETs. values, it is possible to derive the sizes of all the components. cascodes and produce a rectified sine wave at the drain of the transconductors due to the.

The generalized sine-Gordon (sG) equation where u = u ( x , t ) is a scalar-valued function, ν is a real parameter, ∂ 2 x = ∂ 2 /∂ x 2 and the subscripts t and x appended to u denote partial differentiation, has been derived in [ 1 ] using bi-Hamiltonian methods.

Sine-Gordon Equation The sine-Gordon equation is a nonlinear hyperbolic partialdifferential equation in-volving the d’Alembert operator and the sine of the unknown function. The equa-tion, as well as several solution techniques, were known in the nineteenth century in the course of study of various problems of differential geometry. The equation the sine-Gordon equations can be obtained via the Darboux or B˜acklund transformations [21,37] from already known exact solutions. The sine-Gordon equation was the fourth nonlinear partial difierential equation whose initial-value problem was discovered [2,3] to be solvable by the inverse scattering transform method. The generalized sine-Gordon (sG) equation where u = u ( x , t ) is a scalar-valued function, ν is a real parameter, ∂ 2 x = ∂ 2 /∂ x 2 and the subscripts t and x appended to u denote partial differentiation, has been derived in [ 1 ] using bi-Hamiltonian methods.

to the equation obtained from (1.1) by letting = 0) in the same way that the Camassa-Hom (CH) equation (see [3, 11]) is related to the Korteweg-de Vries (KdV) equation. Actually, there exist even deeper analogies between (1.1) and the CH equation.

Made available by U.S. Department of Energy Office of Scientific and Technical Information Notes on The Sine Gordon Equation David Gablinger January 31, 2007 Abstract In this seminar, we will introduce the Sine-Gordon equation, and solve it using a Baecklund transfomation. Furthermore, we also give a numeric solution using a split-step algorithm, and also present two physical applications of the Sine-Gordon equation. 1 Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms Submitted by Emmanuel Lemoine on Wed, 10/29/2014 - 11:46 Titre Derivation of a generalized double-sine-Gordon equation describing ultrashort-soliton propagation in optical media composed of multilevel atoms Finding the energy of a solution to the Sine-Gordon equation.
