Terahertz (THz) light has proven to be a fine tool to probe and control quasi-particles and
collective excitations in solids, to drive phase transitions and associated changes in material …

Electromagnetic radiation in the terahertz (THz) frequency range is a fascinating
spectroscopic tool that provides resonant access to fundamental modes, including the …

“Hidden phases” are metastable collective states of matter that are typically not accessible
on equilibrium phase diagrams. These phases can host exotic properties in otherwise …

The solvation of ions changes the physical, chemical and thermodynamic properties of
water, and the microscopic origin of this behaviour is believed to be ion-induced …

We explore the capabilities of metallic spintronic thin-film stacks as a source of intense and
broadband terahertz electromagnetic fields. For this purpose, we excite a W/CoFeB/Pt …

Ultrashort terahertz pulses derived from femtosecond table-top sources have become a
valuable tool for time-resolved spectroscopy during the last two decades. Until recently, the …

Intense single-cycle THz pulses resonantly interacting with molecular rotations are shown to
induce field-free orientation and alignment under ambient conditions. We calculate and …

In its 60 years of existence, the field of nonlinear optics has gained momentum especially
over the past two decades thanks to major breakthroughs in material science and …

The fundamental properties of water molecules, such as their molecular polarizability, have
not yet been clarified. The hydrogen bond network is generally considered to play an …

We investigate the terahertz (THz)-pulse-driven nonlinear response in the d-wave cuprate
superconductor Bi 2 Sr 2 CaCu 2 O 8+ x (Bi2212) using a THz pump near-infrared probe …
