How Quantum Orders Decouple Under Ultrafast Drive
Cooperative quantum phases arise from the interplay between distinct degrees of freedom- electronic, structural, magnetic, or otherwise- that together stabilize ordered states. When driven out of equilibrium, these intertwined components can respond on different timescales and with unequal resilience. In some cases, electronic order collapses rapidly while structural distortions persist. This selective breakdown reveals how the couplings that bind the system can be weakened, reconfigured, or dynamically removed. We study this phenomenon in 1T-TiSe2, uncovering long-lived, nonthermal states that challenge the indivisibility of hybrid order. Such behavior points toward a new strategy for controlling quantum materials: not by tuning equilibrium phases, but by reshaping their internal dynamics in time.
