Terahertz parametric amplification as a reporter of exciton condensate dynamic

Autor: Haque, S., Michael, M., Zhu, J., Zhang, Y., Windgätter, L., Latini, S., Wakefield, J., Zhang, G., Zhang, J., Rubio, A., Checkelsky, J., Demler, E., Averitt, R.

Condensates are a hallmark of emergence in quantum materials with superconductors and charge density wave as prominent examples. An excitonic insulator (EI) is an intriguing addition to this library, exhibiting spontaneous condensation of electron-ho

Fresnel-Floquet theory of light-induced terahertz reflectivity amplification in Ta2NiSe5

Autor: Michael, M., Haque, S., Windgätter, L., Latini, S., Zhang, Y., Rubio, A., Averitt, R., Demler, E.

We theoretically investigate a new pathway for terahertz parametric amplification, initiated by above-gap optical excitation in the candidate excitonic insulator Ta2NiSe5. We show that after electron photoexcitation, electron-phonon coupling can lead

Strong electron phonon correlation in quasi one-dimensional crystals and the excitonic insulator candidate Ta2NiSe5

Autor: Windgätter, L.

Understanding and controlling the interaction between quasiparticles in quantum materials is still an ongoing endeavour in condensed matter physics. In this thesis the interaction between phononic, electronic and excitonic degrees of freedom is inves

Ta2NiSe5 is one of the most promising materials for hosting an excitonic insulator ground state. While a number of experimental observations have been interpreted in this way, the precise nature of the symmetry breaking occurring in Ta2NiSe5, the ele
