In a stadium, spectators do the wave: they stand and sit, and the wave runs through the rows. In the superconducting crystal Au₆Te₁₂Se₈, scientists saw something similar, but the atoms shift sideways, as if each spectator steps aside. The displacement is record-breaking: 4 angstroms, almost half a nanometer. Usually such charge waves vanish if the sample is made thinner. Here, it’s the opposite: in a micron-thick plate, the wave intensified and appeared at a temperature 20 degrees higher — up to –163°C. In a thick piece, it wasn’t there at all.

Using spectroscopy (transillumination) and computer simulations, they confirmed that the wave is transverse, "pushed" by thermal lattice vibrations. Precise measurements revealed how thermal conductivity changes during the transition. The charge wave interferes with superconductivity, and here a complex quantum state emerges, where waves superimpose and lose their coherence. The most amazing part: the giant atomic shift was seen directly, without complex processing, as if you could see ripples on water with the naked eye, normally only visible under a microscope. This discovery, rooted in the work of Bardeen and Landau, brings us closer to creating materials that can switch between normal and superconducting states.
