Structural glasses model using disorder fields: the boson peak from local ground states
M. M. Balbino, I. P. de Freitas, A. M. S. Macedo +2
We show the emergence of a contribution characteristic of the boson peak in the spectral density of structural glasses. To model the vitreous state, we consider static density-fluc…

Hydrodynamic fields in fluctuating environment: a model for isochoric heat capacity of simple liquids
I. P. de Freitas, F. Sobrero, A. M. S. Macedo +1
Using functional methods, we investigate the sound quanta arising from quantized hydrodynamic fields in simple liquids at low temperatures, under the influence of high-energy proce…
