Zero Point Density Fluctuations and Electron Brownian Motion
L. H. Ford, G. O. Heymans, N. F. Svaiter
The fluctuations in the phonon vacuum state can lead to zero point density fluctuations in a material, which in turn lead to local zero point fluctuations of the dielectric propert…
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…
When Bob orbits Alice: entanglement harvesting in circular motion
F. Sobrero, M. S. Soares, N. F. Svaiter
We study radiative processes of two qubits coupled to a massless scalar field prepared in the Minkowski vacuum state. The analyze the effects of vacuum fluctuations in the generati…
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…
Time-dependent accelerated Unruh-DeWitt detector without event horizon
F. Sobrero, M. S. Soares, T. Guerreiro +1
We investigate unitarily inequivalent representations of the algebra of operators in quantum field theory in the cases where there is a Fock representation of the commutation relat…
