Momentum transfer in the ponderomotive potential of near-infrared laser pulses leads to sizable energy shifts and electron-wavepacket squeezing in time-resolved ARPES
Xinwei Zheng, Martin Weinelt, Christian Strüber
We observe momentum transfer in the ponderomotive potential of near-infrared (NIR) laser pulses in time- and angle-resolved photoemission spectroscopy (tr-ARPES) experiments with u…

Ultrafast non-equilibrium magnon generation and collapse of spin-orbit hybridization gaps in iron
Xinwei Zheng, Shabnam Haque, Christian Strüber +1
We distinguish between longitudinal and transverse spin excitations in the ultrafast response of iron by probing exchange splitting ΔEex and magnetic linear dichroism (MLD) in time…
