Revealing "hidden" phases of matter through the power of light

A new study reveals a "hidden" phase of strontium titanate. On the left, extremely fast light pulses activate atoms in the crystal structure (red arrows), which bring the material into a new ferroelectric phase. Vibrations of other atoms then stabilize the hidden phase (right fields). Picture credits: Felice Macera Most people think that water exists only in one of three …
