We studied the kink-antikink collision process for the "double sine-Gordon" (DSG) equation in 1+1 dimensions at different values of the potential parameter R>0. For small values of R we discuss the problem of resonance frequencies. We give qualitative explanation of the frequency shift in comparison with the frequency of the discrete level in the potential well of isolated kink. We show that in...

We present detailed energy dispersions near the Fermi level along the high symmetry line GammaX on the monolayer and bilayer strontium ruthenates Sr2RuO4 and Sr3Ru2O7, determined by high-resolution angle-resolved photoemission spectroscopy. A kink in the dispersion is clearly shown for the both ruthenates. The energy position of the kink and the slope in the low-energy part near the Fermi level...

Processes of the nucleation and motion of kinks, determining the dislocation mobilities in crystals with high Peierls barriers, are reviewed. Various mechanisms of an influence of point defects on the kink dynamics are analyzed. To demonstrate these mechanisms experimental data are presented obtained with two-level intermittent loading of Si, Ge, and bulk SiGe alloy single crystals. The instabi...

In this paper, by using bifurcation method, we successfully find the K(2, 2) equation with osmosis dispersion ut+(u )x− (u)xxx = 0 possess two new types of travelling wave solutions called kink-like wave solutions and antikink-like wave solutions. They are defined on some semifinal bounded domains and possess properties of kink waves and anti-kink waves. Their implicit expressions are obtained....

We present a new model for the the kink effect in InAlAs/InGaAs HEMT’s. The model suggests that the kink is due to a threshold voltage shift which arises from a hole pile-up in the extrinsic source and an ensuing charging of the surface and/or the buffer-substrate interface. The model captures the many of the observed behaviors of the kink, including the kink's dependence on bias, time, tempera...

We report that kink motion is a universal plastic deformation mode in all carbon nanotubes when being tensile loaded at high temperatures. The kink motion, observed inside a high-resolution transmission electron microscope, is reminiscent of dislocation motion in crystalline materials: namely, it dissociates and multiplies. The kinks are nucleated from vacancy creation and aggregation, and prop...

Recent results on u l h high purity Cu have shown that the Bordoni peak grow very large after annealing at 800 "C . The size of the peak suggests that the bowout of clean network dislocations through the kink pair formation caused the peak. Based on these results, Takeuchi proposed the model in which the Bordoni peak and yield stress at low temperatures are associated respectively with kink pai...

In this paper, we have investigated the effects of asymmetry in the source and drain capacitance of metallic island single electron transistors. By comparing the source and drain Fermi levels, in the ground and source referenced biasing configurations, with the island’s discrete charging energy levels for various gate voltages, we have derived a set of closed form equations for the device thres...

This paper deals with the transmission of a kink in a random medium described by a randomly perturbed sine-Gordon equation. Different kinds of perturbations are addressed, with time or spatial random fluctuations, with or without damping. We derive effective evolution equations for the kink velocity and width by applying a perturbation theory of the inverse scattering transform and limit theore...

We study the spectrum of stable static fermion bags in the 1 + 1 dimensional GrossNeveu model with N flavors of Dirac fermions, in the large N limit. In the process, we discover a new kink, heavier than the Callan-Coleman-Gross-Zee (CCGZ) kink, which is marginally stable (at least in the large N limit). The connection of this new kink and the conjectured S matrix of the Gross-Neveu model is obs...
