  • Terahertz radiation is used to directly probe magnetotransport in metallic multilayers on the timescale of electron momentum scattering—the fundamental conditions of Nevill Mott’s model of spin-dependent conduction in metals.

  • The field effect tunability of 2D semiconductors is at the basis of their technological appeal, but it is usually implemented via electrostatic gating. Here, the authors demonstrate an ultrafast THz field effect in 2D MoS2 embedded in a nanoantenna converting the incident radiation field into an out-of-plane electric field of ~ MV/cm scale.

  • A linear energy–momentum relation of graphene results in a high direct-current electron mobility, but this is not necessarily true at terahertz frequencies. Here, the authors show that its ultrafast conductivity is dependent on a highly nonlinear interplay between heating and cooling of the electron gas.

  • Ultrastrong light-matter interactions with dominant antiresonant terms are expected to give rise to interesting phenomena such as quantum fluctuation suppression. Here, the authors propose a system of ultrastrongly coupled magnon modes in a rare earth orthoferrite as a platform for exploring such phenomena.

  • External stimuli can induce significant changes in the magnetisation of a material; however, these changes can occur very rapidly, making measurements difficult. Herein the authors demonstrate a method of ultrafast magnetometry, enabling the detection of the rapid magnetization changes.

  • A single-source multimodal nonlinear optical imaging system has been developed to probe different endogenous biomolecules. Rapid, stain-free imaging of fresh tissue specimens is possible with short turnaround times for disease diagnosis.

  • Methylammonium lead iodide perovskite, a promising material for efficient photovoltaics, shows a unique temperature dependence of its optical properties. Kim et al. quantify the coupling between the optical gap and a lattice phonon at 1 THz, which favorably contributes to the thermal variation of the gap.

  • Liquid water molecules are in constant vibrational motion, but probing how their local behaviour influences collective dynamics remains a challenge. Here, the authors present terahertz-infrared spectroscopy to elucidate coupling of the O-H stretch vibration to collective, delocalized intermolecular modes.
