Collective lattice dynamics determine essential aspects of condensed matter, such as elastic
and thermal properties. These exhibit strong dependence on the length-scale, reflecting the …

Fully coherent, soft X-ray attosecond pulses are now available through high-order harmonic
generation (HHG); however, the output energy is insufficient for various applications, such …

Nonlinear optical processes lie at the heart of frequency tunable coherent light sources,
including entangled photon sources and squeezed states of light, and they have become …

Heat management is crucial in the design of nanoscale devices as the operating
temperature determines their efficiency and lifetime. Past experimental and theoretical works …

The advent of free electron lasers has opened the opportunity to explore interactions
between extreme ultraviolet (EUV) photons and collective excitations in solids. While EUV …

The absence of efficient light modulators for extreme ultraviolet (EUV) and X-ray photons
considerably limits their real-life application, particularly when even slight complexity of the …
