  • At a zero-temperature phase transition, quantum, rather than thermal, fluctuations determine the behaviour both at the transition and in a finite temperature ‘quantum critical’ region. Here the authors give a quantitative definition of the quantum critical region that could be applied to experimental data.

  • Magnetic quasiparticles in a doped quantum magnet are shown to be well suited for realizing and exploring the ‘glassy’ states that are predicted to emerge for interacting bosons in the presence of disorder.

  • In the dipolar XY model, quench dynamics from a polarized initial state lead to spin squeezing that improves with increasing system size, and two refinements show further enhanced squeezing and extended lifetime of the squeezed state by freezing its dynamics.
