Scientists have used attosecond transient absorption spectroscopy in combination with theoretical many-body modelling to study the non-adiabatic dynamics of carriers and phonons on the atomic scale.[2] This approach revealed non-adiabatic, energy-dependent electronic responses to lattice motion with previously unattained orbital and site specificity in the prototype two-dimensional Ti3C2TX MXene material.The study focused on ultrafast highly non-equilibrium electron-phonon (e-p) dynamics, which are crucial for heat dissipation in microelectronics.[2] The presented approach showed the connections between ultrafast carrier localization dynamics and the strength of electron-phonon coupling.The results represent an important step towards achieving quantum control over energy dissipation in quantum materials.These findings suggest strategies for thermal management in electronics through crystal structure engineering or tuning of phonon modes.The paper was published in Science, volume 391, number 6780, pages 75-78.[2
