Chaotic Dynamics nlin.CD

Physicists ran two programs on a superconducting chip: an orderly one and a chaotic one. By measuring the distances between energy levels, they found that in chaos, these levels keep a respectful distance, like people in a crowded room forming a circle. On a graph, this looks like a 'donut'—an empty

What the work is about: searching for periodic orbits in the three-body problem. What's new: over 10,000 three-dimensional orbits, many of them stable, including round dances and duets with a solo. Why it matters: these refined movements explain the stability of triple star systems and offer a glimp

New research settles an old debate: ice ages are controlled not by complex chemistry but by sunlight. A simple model links the flow of solar heat to ice volume, accurately reproducing 800,000 years of data. The ocean, like a mute, dampens the slow 400,000-year cycle, making the 100,000-year cycle th
