Ultrafast transient increase of oxygen octahedral rotations in a perovskite
M. Porer, M. Fechner, M. Kubli +13
The ability to control the structure of a crystalline solid on ultrafast timescales bears enormous potential for information storage and manipulation or generating new functional s…
Non-perturbative Interband Response of InSb Driven Off-resonantly by Few-cycle Electromagnetic Transients
F. Junginger, B. Mayer, C. Schmidt +5
Intense multi-THz pulses are used to study the coherent nonlinear response of bulk InSb by means of field-resolved four-wave mixing spectroscopy. At amplitudes above 5 MV/cm the si…
Ultrafast Insulator-Metal Phase Transition in VO2 Studied by Multiterahertz Spectroscopy
A. Pashkin, C. Kübler, H. Ehrke +5
The ultrafast photoinduced insulator-metal transition in VO2 is studied at different temperatures and excitation fluences using multi-THz probe pulses. The spectrally resolved mid-…
Femtosecond Quasiparticle and Phonon Dynamics in Superconducting YBa2Cu3O7 Studied by Wideband Terahertz Spectroscopy
A. Pashkin, M. Porer, M. Beyer +10
We measure the anisotropic mid-infrared response of electrons and phonons in bulk YBa2Cu3O7 after femtosecond photoexcitation. A line shape analysis of specific lattice modes revea…
