Athermal domain-wall creep near a ferroelectric quantum critical point

At very low temperature, particle-like objects such as atoms and material phase boundaries become less able to move due to thermally inactivity. Here, Kagawa et al. show that ferroelectric domain walls gain energy for creep motion due to quantum fluctuations at low temperature.
