  • Rare quantum tunneling two-level systems are known to govern the glass physics at low temperatures, but it remains challenging to detect them in simulations. Ciarella et al. show a machine learning approach to efficiently identify the structural defects, allowing to predict the quantum splitting.

  • The frequency scaling exponent of low-frequency vibrational excitations in glasses remains controversial in the literature. Here, Schirmacher et al. show that the exponent depends on the statistics of the small values of the local stresses, which is governed by the detail of interaction potential.
