Coherent energy exchange between carriers and phonons in Peierls-distorted bismuth unveiled by broadband XUV pulses
Romain Géneaux, Iurii Timrov, Christopher J. Kaplan +3
In Peierls-distorted materials, photoexcitation leads to a strongly coupled transient response between structural and electronic degrees of freedom, always measured independently o…

Attosecond time-domain measurement of core-excitonic decay in magnesium oxide
Romain Géneaux, Christopher J. Kaplan, Lun Yue +11
Excitation of ionic solids with extreme ultraviolet pulses creates localized core-excitons, which in some cases couple strongly to the lattice. Here, core-excitonic states of magne…
