  • The heavy-fermion compound YbRh2Si2 possesses a quantum critical point, at which the standard theory of electron behaviour in metals is expected to break down; such anomalous behaviour has now been observed.

  • New theoretical work shows that skyrmions can form stable ground states in various types of magnetic metals and may be observed directly with modern magnetic microscopy techniques. Moreover, it predicts that spontaneous skyrmion ground states exist generally in a large number of materials.
