  Size-controlled quantum dots reveal the impact of intraband transitions on high-order harmonic generation in solids

  Both inter- and intraband transitions contribute to high-harmonic generation in solids, but their exact roles are not fully understood. Experiments with quantum dots show that enhanced intraband transitions lead to increased carrier injection and thus enhanced harmonic generation.

  Real-space imaging of phase transitions in bridged artificial kagome spin ice

  Artificial spin ice formed of nanomagnets arranged on a lattice mimics frustrated magnetism seen in condensed matter. By controlling magnetic interactions, theoretically predicted phase transitions are now observed in artificial kagome-lattice spin ice.

  Binary icosahedral clusters of hard spheres in spherical confinement

  The authors investigate out-of-equilibrium crystallization of a binary mixture of sphere-like nanoparticles in small droplets. They observe the spontaneous formation of an icosahedral structure with stable MgCu₂ phases, which are promising for photonic applications.

  Cooperatively enhanced dipole forces from artificial atoms in trapped nanodiamonds

  The strength of optical trapping of a nanodiamond can be increased by cooperative effects between its numerous colour centres — or artificial atoms: an observation that brings together ideas from atom and nanoparticle trapping.

  Collective magnetic response of CeO₂ nanoparticles

  The magnetic response of nanoparticles made from wide-bandgap oxides that don’t contain any magnetic cations is somewhat of a mystery. Experiments with CeO₂ suggest that the origin may be due to vacuum fluctuations.

  Thermal nonlinearities in a nanomechanical oscillator

  A room-temperature motion sensor with record sensitivity is created using a levitating silica nanoparticle. Feedback cooling to reduce the noise arising from Brownian motion enables a detector that is perhaps even sensitive enough to detect non-Newtonian gravity-like forces.
