Light induced magnetization dynamics can be as fast as few tens of femtoseconds. Here, Zayko et al show ultrafast microscopy based on high-harmonic radiation for direct imaging of ultrafast phenomena and capture femtosecond spin dynamics at the nanos

Femtosecond core-level transient absorption spectroscopy is utilized to investigate photoinduced dynamics of the charge density wave in 1T-TiSe_{2} at the Ti M_{2,3} edge (32–50 eV). Photoexcited carriers and phonons are found to primarily induce s

A key element of optical spectroscopy is the link between observable selection rules and the underlying symmetries of an investigated physical system. Typically, selection rules directly relate to the sample properties probed by light, yielding infor

Fluctuations and stochastic transitions are ubiquitous in nanometre-scale systems, especially in the presence of disorder. However, their direct observation has so far been impeded by a seemingly fundamental, signal-limited compromise between spatial

We use high-sensitivity ultrafast high-harmonic spectroscopy to track coherent phonons in the charge-density wave phase of 1T-TiSe2. Using harmonics near the Ti-M-edge, we distinguish spectral signatures of the 3.3-THz amplitude mode and 6-THz optica

Light-induced magnetization changes, such as all-optical switching, skyrmion nucleation, and intersite spin transfer, unfold on temporal and spatial scales down to femtoseconds and nanometers, respectively. Pump-probe spectroscopy and diffraction stu

We present the first nanoscale imaging of femtosecond phenomena using high-harmonic radiation that combines these extreme scales. Capturing the ultrafast spin dynamics in real-space reveals simultaneously local demagnetization and nonlocal phenomena
