Ultrafast Carrier Relaxation and Second Harmonic Generation in a Higher‐Fold Weyl Fermionic System PtAl

Ultrafast Carrier Relaxation and Second Harmonic Generation in a Higher‐Fold Weyl Fermionic System PtAl

Abstract In topological materials, shielding of bulk and surface states by crystalline symmetries has provided hitherto unknown access to electronic states in condensed matter physics. Interestingly, photoexcited carriers relax on an ultrafast timescales, demonstrating large transient mobility that...
