Published: Photoinduced long-lived state in FeSe0.4Te0.6

We exploit tr-ARPES to study ultrafast electron dynamics in FeSe0.4Te0.6 following photoexcitation by near-infrared pump pulses. By exploiting probe-polarization-dependent matrix element effects, we reveal a photoinduced long-lived state, lasting for a few tens of picoseconds, showing features compatible with a nematic state.
