The nature of non-phononic excitations in disordered systems
Walter Schirmacher, Matteo Paoluzzi, Felix Cosmin Mocanu +4
Using heterogeneous-elasticity theory (HET) and a generalisation of HET theory (GHET), obtained by applying a newly developed procedure for obtaining the continuum limit of the gla…
Diffusion of light in turbid media and Kubelka-Munk theory
Walter Schirmacher, Giancarlo Ruocco
We show that the Kubelka-Munk equations for the description of the intensity transfer of light in turbid media are equivalent to a one-dimensional diffusion equation, which is obta…
The electric and magnetic disordered Maxwell equations as eigenvalue problem
Walter Schirmacher, Thomas Franosch, Marco Leonetti +1
We consider Maxwell's equations in a 3-dimensional material, in which both, the electric permittivity, as well as the magnetic permeability, fluctuate in space. Differently from al…
Instantaneous normal modes in liquids: a heterogeneous-elastic-medium approach
Stefano Mossa, Taras Bryk, Giancarlo Ruocco +1
The concept of vibrational density of states in glasses has been mirrored in liquids by the instantaneous-normal-mode spectrum. While in glasses instantaneous configurations corres…
Terahertz Dynamics in the Glycerol-Water System
Johanna Kölbel, Walter Schirmacher, Evgenyi Shalaev +1
The model glass-former glycerol and its aqueous mixtures were investigated with terahertz-time domain spectroscopy (THz-TDS) in the frequency range of 0.3--3.0\,THz at temperatures…
Comment on "Explaining the specific heat of liquids based on instantaneous normal modes"
Walter Schirmacher, Taras Bryk, Giancarlo Ruocco
In a recent paper (Phys. Rev. E {\bf 104}, 014103 (2021) ) M. Baggioli and A. Zaccone formulate a theoretical description of the specific heat of liquids by using Debye's expressio…
