Ultrafast Faraday Rotation Probe of Chiral Phonon-Polaritons in LiNbO3
Megan F. Biggs, Sin-hang, Ho +4
Time reversal symmetry breaking motion of chiral phonon-polaritons in LiNbO3 is probed via the ultrafast Faraday effect. By combining a pair of perpendicularly polarized THz pulses…

-Induced Artifact Overwhelming the Third-Order Signal in 2D Raman-THz Spectroscopy of Non-Centrosymmetric Materials
Seyyed Jabbar Mousavi, Megan F. Biggs, Jeremy A. Johnson +2
Through comprehensive data analysis, we demonstrate that a -induced artifact, arising from imperfect balancing in the conventional electro-optic sampling (EOS) detection s…
