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…
Weak- and strong-disorder effects in the continuous random-field Ising model
G. O. Heymans, N. F. Svaiter, B. F. Svaiter +1
We discuss the weak- and strong-disorder effects in the continuous random-field Ising model using the distributional zeta-function method. In the weak-disorder regime, the vacuum i…
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…
Bounds in partition functions of the continuous random field Ising model
G. O. Heymans, N. F. Svaiter, B. F. Svaiter +1
We investigate the critical properties of continuous random field Ising model (RFIM). Using the distributional zeta-function method, we obtain a series representation for the quenc…
Repulsive to Attractive Fluctuation-Induced Forces in Disordered Landau-Ginzburg Model
C. D. Rodríguez-Camargo, A. Saldivar, N. F. Svaiter
Critical fluctuations of some order parameter describing a fluid generates long-range forces between boundaries. Here, we discuss fluctuation-induced forces associated to a disorde…
Fluctuation-Induced Forces in Disordered Landau-Ginzburg Model
C. D. Rodriguez Camargo, A. Saldivar, N. F. Svaiter
We discuss fluctuation-induced forces in a system described by a continuous Landau-Ginzburg model with a quenched disorder field, defined in a -dimensional slab geometry $\mathb…
