Internal Stresses as Origin of the Anomalous Low-Temperature Specific Heat in Glasses
Walter Schirmacher, Giancarlo Ruocco
We apply a recently developed theory of the nonphononic vibrational density of states (DOS) in glasses to investigate the impact of local frozen-in stresses on the low-temperature…

Exotic collective dynamics in molten Carbon
Taras Bryk, Giancarlo Ruocco, Jean-François Wax +1
Collective longitudinal and transverse propagating modes in molten Carbon at ~K and pressure range - GPa are reported from {\it ab initio} based as well as machine…

Comment on "Universal effect of excitation dispersion on the heat capacity and gapped states in fluids"
T. Bryk, N. Jakse, I. Mryglod +2
We discuss the validity of recent results in [Phys. Rev. Lett. 125, 125501 (2020)] on an universal relation between the heat capacity and dispersions of collective excitations in l…
