Time-resolved THz Stark spectroscopy of molecules in water
Elnaz Zyaee, Vladislav Slama, Seyyed Jabbar Mousavi +3
Stark spectroscopy is a powerful method for probing molecular dipole moment changes, charge transfer dynamics, and polarizability under applied electric fields. Time-Resolved Terah…

Anharmonic phonon coupling enabled by local inversion symmetry breaking at domain walls in ferroelastics
Seyyed Jabbar Mousavi, Vivek Unikandanunni, Niccolo Sellati +7
In ferroelastic materials, spontaneous symmetry breaking leads to the formation of twin domains. Although the bulk crystal typically remains centrosymmetric, inversion symmetry can…

-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…
