Ultrafast spectroscopy and control of correlated quantum materials
… generation evidence for an amplitude-mode electromagnon in CuBr₂. I conclude by reflecting on the progress achieved in correlated electron physics as a result of this work, and by giving my own perspective on the future of this field.

Controlling and probing nonlinear collective mode dynamics in quantum materials
… in which spatially heterogeneous responses of electromagnon modes in a van der Waals multiferroic are revealed through terahertz photon echo measurements. Together, these results highlight how tailored light-matter interactions can be leveraged to probe, control, and manipulate material degrees …

Mueller matrix spectroscopic ellipsometry of multiferroics
… shown in the far-IR Mueller matrix spectra of electromagnon excitations. Detail studies of optical properties of hexagonal multiferroic oxides RMnO_3, (R = Ho, Er, Tm, Yb, and Lu), are studied in the far-infrared spectral range between 100 and 2000 cm-1 and temperatures between 1.5 K and 300 K …

Ultrafast Terahertz Spectroscopy for the Manipulation and Elucidation of Correlated Quantum Materials
… evidence for a new type of quasiparticle, an electromagnon-polariton, is demonstrated in a non-equilibrium sample. Further, preliminary data regarding the measurement of a new type of Kondo hybridization gap (a pseudogap) in the kagome strange metal Ni3In is reported using the photoexcited …

Analysis of far-infrared optical spectra of multiferroics
The optical spectra of multiferroic crystals Dy_3Fe_5O_{12}, Tb_3Fe_5O_{12}, and four hexagonal RMnO_3 (5D= Er, Tm, Yb, Lu) are studied using intense bright synchrotonic light in the infrared spectral range. In regards to the materials analyzed, two rare earth iron garnets and four rare earth …
