We investigate existence and stability of time periodic solutions for damped Sine-Gordon equations with delay under reasonable assumptions. The key-step is constructing suitable Lyapunov functionals and establishing the priori bound for all possible periodic solutions. We also use the Schaefer fixed-point …

Gogolin arXiv:cond-mat/0203294v2 7 Jun 2002 Department of Mathematics, Imperial College, 180 Queen’s Gate, London SW7 2BZ, United Kingdom Efficient fixed-point sine and cosine algorithms are critical to many embedded applications, including motor controls, navigation, signal processing, and wireless communications. Calculating Sine and Cosine Using the CORDIC Algorithm The Fixed-Point Designer software would automatically store F as 1.3332 and E as -2 because of the normalization condition of 1 ≤ F < 2. To set up the model to use [Slope Bias] scaling: Configure the Signal Generator block to output a sine wave signal with an amplitude defined on the interval [-5 5] . Abstract. We demonstrate that ß-kinks can exist in non-parametrically AC driven sineGordon systems if the AC drive is sufficiently fast. It is found that, at a critical value of the drive amplitude, there are two stable and two unstable fixed points in the sine-Gordon phase.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We demonstrate that ß-kinks can exist in non-parametrically AC driven sineGordon systems if the AC drive is sufficiently fast. It is found that, at a critical value of the drive amplitude, there are two stable and two unstable fixed points in the sine-Gordon phase.

This model is reduced to the conventional sine-Gordon model that describes the Kosterlitz-Thouless transition near the fixed point. In the strong-coupling limit, the model is reduced to a U(N) matrix model. Fig. Renormalization group flow for the SU(N) sine-Gordon model [18].

Conceptual overview. The value of the parameters of the system at which the phase transition occurs defines the “critical point”. In the symmetry breaking phase invariance is lost at a certain characteristic energy scale (commonly called. “mass” or “gap”) which is associated to the degree of order in the system.

2002-09-16 · The Z 3 infrared critical properties of the β 2 =6π self-dual sine-Gordon model are derived using two non-perturbative approaches. On one hand, we map the model onto an integrable deformation of the Z 4 parafermion theory. The latter is known to flow to a massless Z 3 infrared fixed point. XXZ/Sine-Gordon equivalence, paramter correspondance; Luther point in XXZ? It has been argued that isotropic XXZ model corresponds to an SG theory which flows to K = 1, u = 0 fixed point. AFM XXZ model should correspond to some SG theory with K>1, u>0, which is dual to a massive Thirring model.

The designation “sine-Gordon” is also used for various equations that generalize [1] or bear resemblance to it. These include the so-called homogeneous and symmetric space sine-Gordon models, discrete and supersymmetric versions, and generalizations to higher-dimensional spacetimes (i.e., in [1] the spatial derivative is replaced by the Laplace operator in several variables).

The impurity entropy, the impurity specific heat and the conductance are calculated. A delicate point is to put in relation the 4D sine-Gordon model and a suitable O (2) model.
