Subcycle videography of Landau–Zener–Majorana transitions in graphene - Nature

An experimental concept enabling attosecond-precision, subcycle band-structure videography covering the entire first Brillouin zone is demonstrated and used to visualize the lightwave-driven electron motion of Landau–Zener–Majorana transitions in gr…

Experimental setup
The subcycle momentum microscopy setup (Extended Data Fig.1a) is based on two ytterbium-doped potassium gadolinium tungstate (Yb:KGW) amplifiers (CARBIDE, Light Conversion Inc.). …
