A new scientific frontier opened in 2009 with the start of operations of the world's first x-ray
free-electron laser (FEL), the Linac Coherent Light Source (LCLS), at SLAC National …

This review provides a comprehensive overview of the applications of helium nanodroplets
in the study of ensembles of atoms and molecules, ie clusters and complexes. These …

Self-bound quantum droplets are a newly discovered phase in the context of ultracold
atoms. In this Letter, we report their experimental realization following the original proposal …

The extreme energy densities generated by ultra-relativistic collisions between heavy atomic
nuclei produce a state of matter that behaves surprisingly like a fluid, with exceptionally high …

Self-bound many-body systems are formed through a balance of attractive and repulsive
forces and occur in many physical scenarios. Liquid droplets are an example of a self-bound …

X-ray free-electron lasers (XFELs) and table-top sources of x-rays based upon high
harmonic generation (HHG) have revolutionized the field of ultrafast x-ray atomic and …

The extreme energy densities generated by ultra-relativistic collisions between heavy atomic
nuclei produce a state of matter that behaves surprisingly like a fluid, with exceptionally high …

Intense femtosecond x-ray pulses from free-electron laser sources allow the imaging of
individual particles in a single shot. Early experiments at the Linac Coherent Light Source …

It was recently found that the Lee-Huang-Yang (LHY) correction to the mean-field
Hamiltonian of binary atomic boson condensates suppresses the collapse and creates …

The ability to observe ultrafast structural changes in nanoscopic samples is essential for
understanding non-equilibrium phenomena such as chemical reactions, matter under …
