Thirty Femtoseconds Opened a Hidden State
Six-femtosecond laser pulses exposed a transient bond-order wave that precedes a light-induced state in a metal-organic framework.
Summary
Six-femtosecond laser pulses exposed a transient bond-order wave that precedes a light-induced state in a metal-organic framework.
Researchers at Science Tokyo, Tohoku University and Nagoya Institute of Technology tracked reflectance immediately after a metal-organic framework absorbed light. Experiment and theory indicate that a short-lived bond-order wave, with alternating stronger and weaker electronic bonding, forms before atomic shifts establish a potentially polar hidden state within about 30 femtoseconds. The July 22 Physical Review Letters result reveals an intermediate step and a way to study light-controlled materials, not a ready high-speed device.
