When Graphs Refuse to Quantum Dance with Symmetry

Symmetry Beyond the Classical Horizon Symmetry is a language nature speaks fluently, from the petals of a flower to the orbits of planets. In mathematics, symmetry often reveals itself through automorphisms — transformations that shuffle parts of an object without changing its essence. For graphs, these automorphisms are permutations of vertices preserving connections, the classical…

A Giant THz Wave Rides the Plasma Wake

When a ultrafast laser dives into a gas, it leaves behind more than a bright flash of light. It carves a wake in the plasma, a sweeping ripple that can accelerate electrons to remarkable energies. In a new strand of experiments, scientists have found something else riding that wake: a giant, coherent terahertz surface wave…
