Scientists reveal how laser pulses reshape crystal structures in charge-density materials

Researchers discovered that ultrafast laser bursts can dramatically stiffen atomic vibrations and reconstruct the internal structure of titanium diselenide without generating heat. The finding could unlock new ways to manipulate materials for quantum computing and advanced electronics by controlling their properties on picosecond timescales.
