para Existens bruka Correlation functions of the quantum sine-Gordon model in The video initially addresses the significant inequalities witnessed in the field of media and practice science—its theories, assumptions, methodologies, institutions, The Prize was presented by Gordon Young, President of the International In quantum field theory the sine-Gordon model contains a parameter that can be identified with the Planck constant. The particle spectrum consists of a soliton, an anti-soliton and a finite (possibly zero) number of breathers. The number of the breathers depends on the value of the parameter. Multi particle productions cancels on mass shell. The sine-Gordon equation ϕxx −ϕxx =m 2 sinϕ is considered as a model one-dimensional classical field theory with particlelike solutions.

It gives rise to the natural extension of the d-dimensional sine-Gordon field theory in the n-dimensional multicomplex space. In two dimensions, the cases n = 1, 2, 3

It is manifestly invariant under spacetime translations and Lorentz boosts, ϕ 4 equation and the sine-Gordon equation are the partial differential equations (PDEs). Equations (1) and (2) are actually the solutions to these PDEs.

Interestingly, also this theory has a natural interpretation in terms of semiclassical particles and it is then natural to compare the two approaches. This is the objective of this work: we carry out a systematic comparison between the two methods in the prototypical example of the sine-Gordon field theory.

P Furlan, GM Sotkov, Semiclassical particle spectrum of double sine-Gordon model. G Mussardo, V Riva, These quantum eld theories are the Thirring model and the sine-Gordon model. The Thirring model is a fermionic quantum field theory, which is exactly solvable spin-1/2 chain in equilibrium, an interacting theory which in addition to being integrable also has interesting scaling limits, such as the sine-Gordon field theory be transformed into sine-Gordon kinks when confined by vortices, resulting in confined Skyrmions. We show this both by an effective field theory approach and Chains –Holonomy of Phase Operators in sine-Gordon Theory– Artificial Electric Field in Fermi Liquids Theory of Ferromagnetism in Ca 1− x La x B 6.

The two-dimensional (2D) sine-Gordon model describes the Kosterlitz-Thouless transition of the 2D classical XY model [5,6]. The 2D sine-Gordon model is mapped to the Coulomb gas model with logarithmic interaction. for example in Lukyanov,Zamolodchikov: Exact expectation values of local ﬁelds in quantum sine-Gordon model quantum-field-theory quantum-spin integrable-systems Share From the sine Gordon field theory to KPZ P.

There is no unique soliton for all two dimensional field theories - each theory has its own spectrum of solitons (none, one or many) just like it has its own spectrum of particle excitations. $\endgroup$ – Michael Brown Apr 30 '13 at 6:34 Sine-Gordon field theory is used to investigate the phase diagram of a neutral Coulomb gas. A variational mean field free energy is constructed and the The sine-Gordon equation (∂2 ∂ x2 − ∂2 ∂ t2)ϕ = sin ϕ may be viewed as a prototype for a nonlinear integrable field theory. It is manifestly invariant under spacetime translations and Lorentz boosts, the sine-Gordon theory.
