  • Two adjacent quantum time crystals implemented by two magnon condensates in the superfluid B-phase of helium-3 are observed to coherently exchange magnons as a manifestation of the AC Josephson effect, offering insights on the dynamics and interactions between these phases of matter.

  • Relaxor ferroelectric polymers are a material of choice for applications such as electrostrictive actuators or electrocaloric cooling. Here, the origin of relaxor behaviour at the molecular level is investigated and found to arise from conformational disorder.

  • Flexoelectricity is the ability of materials to generate electricity upon bending. Here it is demonstrated that adding light to mechanical oscillation enhances effective flexoelectric coefficients by orders of magnitude, with the halide perovskites showing the largest coefficients.
