  • Multiferroic quantum criticality — associated with the merging of two distinct quantum critical points — is explored, with implications for fundamental physics and low-temperature applications.

  • Superconductivity in low-carrier-density polar metals, such as SrTiO3, challenges the conventional electron-phonon theory due to the absence of retardation required to overcome Coulomb repulsion. Here, the authors propose that energy fluctuations of quantum-critical phonons could account for the superconductivity of SrTiO3.

  • The formation of Ising quasiparticles in URu2Si2 results from ‘hastatic’ order, which breaks double time-reversal symmetry, mixing states of integer and half-integer spin, and accounts for the large entropy of condensation and the magnetic anomaly observed in torque magnetometry.
