Ultrafast lattice and electron dynamics induced in a PbSe crystal by an intense terahertz pulse
A. A. Melnikov, Yu. G. Selivanov, D. G. Poydashev +1
We have studied the ultrafast optical response of a PbSe crystal to an intense picosecond terahertz pulse with a peak electric field strength of up to 500 kV/cm. The reflect…
Phonon-driven ultrafast symmetry lowering in a BiSe crystal
A. A. Melnikov, Yu. G. Selivanov, S. V. Chekalin
Selective excitation of coherent high-amplitude vibrations of atoms in a solid can induce exotic nonequilibrium states, in which the character of interactions between electronic, m…
Anisotropic ultrafast optical response of terahertz pumped graphene
A. A. Melnikov, A. A. Sokolik, A. V. Frolov +2
We have measured the ultrafast anisotropic optical response of highly doped graphene to an intense single cycle terahertz pulse. The time profile of the terahertz-induced anisotrop…
Coherent phonons in a film generated by an intense single-cycle THz pulse
A. A. Melnikov, K. N. Boldyrev, Yu. G. Selivanov +3
We report an observation of coherent phonons of , , , and symmetry generated in a single-crystal film of by an intense single-cycle THz p…
Generation of coherent phonons in bismuth by ultrashort laser pulses in the visible and NIR: displacive versus impulsive excitation mechanism
A. A. Melnikov, O. V. Misochko, S. V. Chekalin
We have applied femtosecond pump-probe technique with variable pump wavelength to study coherent lattice dynamics in Bi single crystal. Comparison of the coherent amplitude as a fu…
