Terahertz electro-optic effect in Bi $_{2}$ Se $_{3}$ crystals

A. A. Melnikov, A. A. Sokolik, Yu. G. Selivanov +1

We report the observation of the electro-optic effect in Bi $_{2}$ Se $_{3}$ crystals induced by an intense single-cycle terahertz pulse. The effect reveals itself as a transient change o…

Anharmonic coherent dynamics of the soft phonon mode of a PbTe crystal

A. A. Melnikov, Yu. G. Selivanov, S. V. Chekalin

We investigate the ultrafast optical response of PbTe to an intense single-cycle terahertz pulse, resonant with the soft transverse optical (TO) phonon mode of the crystal. We dete…

Anomalous behavior of the $E_{u}^{1}$ infrared-active phonon mode in a Bi $_{2 - x}$ Sr $_{x}$ Se $_{3}$ crystal

A. A. Melnikov, K. N. Boldyrev, Yu. G. Selivanov +1

We have studied spectral evolution of the $E_{u}^{1}$ phonon line of a topological insulator Bi $_{2 - x}$ Sr $_{x}$ Se $_{3}$ with temperature. Unlike the Raman-active phonons, the $E_{u}^{1}$ mode…
