Optical Rectification and Electro-Optic Sampling in Quartz
Vasileios Balos, Martin Wolf, Sergey Kovalev +1
We report electro-optic sampling (EOS) response and terahertz (THz) optical rectification (OR) in z-cut alpha-quartz. Due to its small effective second-order nonlinearity, echo-fre…
Rotational Coherence of Encapsulated Ortho and Para Water in Fullerene-C60
Sergey S. Zhukov, Vasileios Balos, Gabriela Hoffman +13
Encapsulation of a single water molecule in fullerene-C60 via chemical surgery provides a unique opportunity to study the distinct rotational dynamics of the water spin isomers at…
Terahertz-Magnetic-Field Induced Ultrafast Faraday Rotation of Molecular Liquids
Vasileios Balos, Genaro Bierhance, Martin Wolf +1
Rotation of the plane of the polarization of light in the presence of a magnetic-field, known as the Faraday rotation, is a consequence of the electromagnetic nature of light and h…
Energy Transfer within the Hydrogen Bonding Network of Water Following Resonant Terahertz Excitation
Hossam Elgabarty, Tobias Kampfrath, Douwe Jan Bonthuis +7
Energy dissipation in water is very fast and more efficient than in many other liquids. This behavior is commonly attributed to the intermolecular interactions associated with hydr…
Anharmonic Coupling between Intermolecular Motions of Water Revealed by Terahertz Kerr Effect
Tobias Kampfrath, Martin Wolf, Mohsen Sajadi
Formation of local molecular structures in liquid water is believed to have marked effect on the bulk properties of water, however, resolving such structural motives in an experime…
The sign of the polarizability anisotropy of polar molecules is obtained faithfully from terahertz Kerr effect
Tobias Kampfrath, Martin Wolf, Mohsen Sajadi
Optically heterodyned detected terahertz Kerr effect of gases of polar molecules is reported. Strikingly, the birefringence signal from fluoroform is found to have opposite polarit…
Ultrabroadband single-cycle terahertz pulses with peak fields of 300 kV cm from a metallic spintronic emitter
T. Seifert, S. Jaiswal, M. Sajadi +5
To explore the capabilities of metallic spintronic thin-film stacks as a source of intense and broadband terahertz electromagnetic fields, we excite a W/CoFeB/Pt trilayer on a larg…
Transient birefringence of liquids induced by terahertz electric-field torque on permanent molecular dipoles
Mohsen Sajadi, Martin Wolf, Tobias Kampfrath
Microscopic understanding of low-frequency molecular motions in liquids has been a longstanding goal in soft-matter science. So far, such low-frequency motions have mostly been acc…
