Black Hole Entropy with Modified Dispersion Relations

Communications in Theoretical Physics, 2009
There is much interest in resolving the quantum corrections to Bekenstein–Hawking entropy with a large length scale limit. The leading correction term is given by the logarithm of black hole area with a model-dependent coefficient. Recently the research for quantum gravity implies the emergence of a modification of the energy-momentum dispersion ...

Maximum entropy analysis of dispersed seismic signals

Geophysics, 1986
Abstract Conventional moving-window analyzers based on Fourier transforms sometimes lack the resolution required to separate each of the modes in a seismic wave-guide. It is possible to enhance the resolution of a moving-window analyzer by using a maximum entropy power spectral estimator to approximate the spectrum of each windowed ...

Entropy-induced dispersion of bulk liquids

Journal of Colloid and Interface Science, 1975
Abstract The possibility that two-phase fluid systems will emulsify spontaneously, due to entropy effects, is investigated theoretically. It is discovered that for interfacial tensions below about 2 dynes/cm, such spontaneous dispersions can occur, although with large tensions the dispersed particles are not macroscopic.

Instability and entropy for a class of dispersing billiards

Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 1998
Summary: The billiard in the exterior of a finite disjoint union \(K\) of strictly convex bodies in \(\mathbb{R}^d\) with smooth boundaries is considered. The existence of global constants \(0

Dispersive graded entropy on computing dynamical complexity

Physica A: Statistical Mechanics and its Applications, 2018
Abstract We propose a phase space based statistical disorder to investigate the dynamical complexity of chaotic models. The statistical disorder is defined by introducing a grade function, inversely maps the mean dispersion of the trajectories in the phase space. We denote the associate entropy by the dispersive graded entropy (DGE).
