    Review Article
  • Magnetic molecules have been widely proposed for different quantum technologies due to their bewildering quantum properties. This Review describes techniques of paramount importance for the characterization, understanding and, ultimately, manipulation of the electronic properties of these systems.

  • Phonon heat conduction at the microscale and the nanoscale exhibits rich phenomena beyond the predictions of Fourier’s law, rivalling the phenomena of electrons. This Review discusses phonon heat conduction regimes, including the Casimir–Knudsen size effect, hydrodynamic transport, coherent transport (from quantization and localization) and divergence.

    Research Highlight
  • Majorana zero modes are non-Abelian anyons that hold promise for realizing topologically protected quantum computation. This Review discusses how scanning tunnelling microscopy can identify Majorana zero modes and investigate their properties, and outlines future research direction of the field.

    Review Article
  • Anecdotal but elusive reports suggest that hot water quenched in a cold container can sometimes begin to freeze sooner than warm water under similar initial conditions. John Bechhoefer and colleagues discuss recent experiments that show how this ‘Mpemba effect’ can be reliably reproduced and quantitatively understood.
