We report an experimental study of the 2D dynamics of active particles driven by quantum
vortices on the free surface of superfluid helium at T= 1.45 К. The particle motion at short …

Directly observing atomic motions in molecules during chemical dynamics has long
constituted one of the grand challenges in chemistry. 1 The emergence of X-ray free …

We report electron diffraction results of xenon clusters formed in superfluid helium droplets,
with droplet sizes in the range of 10 5–10 6 atoms/droplet and xenon clusters from a few to a …

We address the collision of two superfluid 4 He droplets at non-zero initial relative velocities
and impact parameters within the framework of liquid 4 He time-dependent density …

Within density functional theory, we have studied self-sustained, deformable, rotating liquid
He cylinders subject to planar deformations. In the normal fluid He 3 case, the kinetic energy …

Diffraction before destruction1, 2 has been a key vision driving the development and
construction of extreme ultraviolet (XUV) and X-ray free-electron lasers (FELs; see Chapter …
