We are pleased to announce a Talk on Thursday, February 5th, at 10:30, at Seminarraum 01.332 (A3), Staudtstraße 7, Erlangen. The talk, titled “Emergent quantum states in driven one-dimensional cuprates” will be presented by Sophia TenHuisen, Havard University.
This event is open to all and is organized and hosted by Daniele Fausti.
Abstract:
Ultrafast optical excitation of quantum materials can reveal hidden electronic states without equilibrium analogs. One-dimensional correlated systems are particularly compelling in this context, as they host rich many-body physics while remaining amenable to accurate theoretical modeling. Using time-resolved x-ray absorption and resonant inelastic scattering, we show how tailored optical excitation induces emergent driven states in the one-dimensional cuprate Sr2CuO3 and the ladder compound Sr14Cu24O41. In both systems, photoexcitation drives a redistribution of charge carriers detected by time-resolved XAS, while time-resolved RIXS exposes new low-energy charge excitations absent in the unperturbed state. Magnetic correlations remain largely intact, underscoring the selectivity of the light–matter interaction. In Sr2CuO3, these photoinduced states decay rapidly, whereas in Sr14Cu24O41 they evolve into metastable configurations persisting for nanoseconds. This combined ultrafast–x-ray approach defines a new framework for capturing and designing emergent quantum phases in correlated systems.
