Congratulations to physicists for reaching such a stunning breakthrough. Their innovation consisted of a new kind of soliton, dubbed a “breathing” soliton, which remained stable over long timescales, even in systems in which energy is not conserved. Jonas Veenstra and his fellow collaborators are at the forefront of this advanced research. Their foundational research provides new perspectives on wave phenomena in various fields of physics, including shallow water, optics, and magnetic fields.
Solitons are fascinating waveforms that maintain their shape and direction for long distances and times. This wondrous quality renders them exceedingly mysterious to scientists. In 1834, engineer John Scott Russell stumbled upon a captivating phenomenon. Solitons first came to his attention while walking the banks of Scotland’s Union Canal. Since then, the field of solitons research blossomed, with scientists and mathematicians exploring the phenomenon in fields ranging from fluid dynamics to electromagnetic waves.
Understanding Solitons
Solitons are incredibly interesting waveforms that aren’t like most waves. They originate from a sensitive interplay between nonlinearity and dispersion in a given medium. Unlike normal waves that waste energy and eventually disperse, solitons can move eternally without changing form. This rare trait allows for broad research across various fields of physics. Wave effects are at the center of this research.
The initial theoretical explanation came in 1895 from Diederik Korteweg and Gustav de Vries, who found the mathematical framework that allowed scientists to describe the behavior of solitons. Their efforts formed the foundation that began to explain how these stable waves worked, and how they propagate through various media. In the decades since, scientists have found solitons in a variety of environments.

The study of solitons has expanded into magnetic fields and other domains, revealing their versatility and importance in modern physics. Researchers are constantly looking for new ways to create and control solitons to study their behavior under many different conditions.
The Creation of Breathing Solitons
In a remarkable advance, Jonas Veenstra and his crew at the University of California, Davis, have produced tabletop-sized soliton or “particle” beams. They’ve added an amazing new twist: breathing solitons. These solitons are unique in that they oscillate in amplitude but retain their stability for an indefinite period. This innovation is more than just cool because this breakthrough is happening in systems which are not bound by classical energy conservation laws.
To investigate these breathing solitons, Veenstra’s group utilized a system developed in Corentin Coulais’ lab, which comprises active mechanical oscillators. This modular arrangement consists of small, solid rods powered by individual micromotors and connected through elastic bands. The design makes possible the formation of solitonic waves, giving researchers a highly controlled environment in which to study these phenomena.
The research team first witnessed the appearance of the first experimental breather soliton six years ago. Since then, they have been working on improving their experimental conditions. Their objective is to identify the precise circumstances necessary for stable propagation of these solitons under the influence of non-reciprocal forces. Their continuing research strives to figure out how solitons behave on two-dimensional surfaces of non-reciprocal oscillators. We hope that this work will lead to interesting and fruitful new directions in probing wave dynamics.
Implications for Future Research
The first evidence of breathing solitons, a fundamental wave phenomenon with deep connections to optics and beyond. Their robustness in non-conservative systems can push technological progress in several important technologies. This spills over into other disciplines such as telecommunications and materials science, where wave propagation is a fundamental component. The long-range potential to control the persistence of soliton states might even lead to new approaches for data transmission, or increase the efficiency of energy systems.
As Veenstra and his collaborators continue their investigations, they are likely to uncover more about the intricacies of soliton behavior. From their work, we hope that new theories or even applications will arise that take advantage of these unique waveforms in novel and creative ways.
