Nature Physics, Published online: 11 November 2019; doi:10.1038/s41567-019-0705-3

Short pulses of light shift the balance between two competing charge density wave phases, allowing the weaker one to manifest transiently while suppressing the stronger one. This shows that competing phases can be tuned in a non-equilibrium setting.
