Motivated by the work of Jang et al., Nat Commun 6:7370 (2015), where the authors experimentally tweeze cavity solitons in a passive loop of optical fiber, we study the amenability to tweezing of cavity solitons ...
Article
Solitons are nonlinear solitary waves which maintain their shape over time and through collisions, occurring in a variety of nonlinear media from plasmas to optics. We present an experimental and theoretical s...

Article
We investigate the generation and propagation of solitary waves in the context of the Hertz chain and Toda lattice, with the aim to highlight the similarities, as well as differences between these systems. We ...
Chapter
The interplay of nonlinearity and topology results in many novel and emergent properties across a number of physical systems such as chiral magnets, nematic liquid crystals, Bose–Einstein condensates, photonic...
Chapter
We explore a \(\phi ^4\) model with an added external parabolic potential term. This term dramatically alters the spectral prop...
Chapter
In this chapter, we touch upon the wide topic of discrete breathers with a special emphasis on the prototypical system of interest, namely the ...
Chapter
Exceptional dicretizations of the \(\phi ^4\) model are reviewed, corresponding conservation laws are reported, and the propert...
Article
Quantum vortices, the quantized version of classical vortices, play a prominent role in superfluid and superconductor phase transitions. However, their exploration at a particle level in open quantum systems h...
Chapter
Shock waves are nonlinear structures characterized by a discontinuous jump in the wave profile. There exist prototypical examples of partial differential equations (PDEs), including the well-known Burgers’ equ...
Chapter
As indicated in the introductory chapter, discrete breathers are one of the most prototypical excitations that can arise in nonlinear dynamical lattices. They are periodic in time and strongly localized in spa...
Chapter
In this section, we finally return to the Newton’s cradle shown in Fig. 1 and Fig. 28a. When the chain of balls is struck at one end, the ball on the opposite end is ejected from the chain, providing a nice il...
Chapter
In the present short volume our aim will be to explore a variety of nonlinear wave structures that are found in a particular physical system, i.e., granular crystals. Many of the readers have almost certainly ...
Chapter
Two-dimensional granular crystals have been investigated far less than 1D configurations. In two spatial dimensions, the nodes can be arranged in a number of ways. While the role of disorder is of particular i...
Chapter
In the present work, we consider the existence, stability, and dynamics of solitary waves in the nonlinear Dirac equation. We start by introducing the Soler model of self-interacting spinors, and discuss its l...
Chapter
Arguably, the most prototypical nonlinear wave structure that can arise in granular crystals consists of traveling waves. While many kinds of traveling waves exist (such as periodic ones [1]), in this chapter we ...
Chapter
Of the three primary structures of interest in this book, solitary waves and breathers have been studied in heterogeneous granular chains, while dispersive shock waves have not. The latter represents an area o...
Article
When mathematical and computational dynamic models reach infinity in finite time, extending analysis and numerics beyond it becomes a notorious challenge. We suggest how, upon suitable transformations, it may ...
Article
In the present work, we consider the mass in mass (or mass with mass) system of granular chains, namely, a granular chain involving additionally an internal (or, respectively, external) resonator. For these ch...
