“…At the late stages of the Hawking evaporation process, one should take into account the strong effects coming from the underlying theory of quantum gravity that can modify Hawking temperature [1] and Bekenstein entropy [3]. These modifications expressed in terms of generalized uncertainty principle (GUP) have been investigated in the context of string theory [26][27][28][29][30], loop quantum gravity [31,32], modified dispersion relations and from black hole physics [34,[36][37][38][39][40][41][42][43][44][45]. As a consequence of these modifications, black holes do not evaporate completely and are left with a remnant of order of Planck size arXiv:1801.09660v3 [gr-qc] 22 Feb 2018 with finite entropy.…”

Generalized uncertainty principle impact onto the black holes information flux and the sparsity of Hawking radiation

We investigate the generalized uncertainty principle (GUP) corrections to the entropy content and the information flux of black holes, as well as the corrections to the sparsity of the Hawking radiation at the late stages of evaporation. We find that due to these quantum gravity motivated corrections, the entropy flow per particle reduces its value on the approach to the Planck scale due to a better accuracy in counting the number of microstates. We also show that the radiation flow is no longer sparse when the mass of a black hole approaches Planck mass which is not the case for non-GUP calculations.

Considerable attention has been devoted to the wormhole physics in the past 30 years by exploring the possibilities of finding traversable wormholes without the need for exotic matter. In particular, the thin-shell wormhole formalism has been widely investigated by exploiting the cut-and-paste technique to merge two space-time regions and to research the stability of these wormholes developed by Visser. This method helps us to minimize the amount of the exotic matter. In this paper, we construct a four-dimensional, spherically symmetric, dyonic thin-shell wormhole with electric charge , magnetic charge , and dilaton charge Σ, in the context of Einstein-Maxwell-dilaton theory. We have applied Darmois-Israel formalism and the cut-and-paste method by joining together two identical space-time solutions. We carry out the dyonic thin-shell wormhole stability analyses by using a linear barotropic gas, Chaplygin gas, and logarithmic gas for the exotic matter. It is shown that, by choosing suitable parameter values as well as equation of state parameter, under specific conditions, we obtain a stable dyonic thin-shell wormhole solution. Finally, we argue that the stability domain of the dyonic thin-shell wormhole can be increased in terms of electric charge, magnetic charge, and dilaton charge.

“…For this purpose, many kinds of energy of states (EOS) are used that are also familiar to us from cosmological models, such as Chaplygin gas [59], generalized Chaplygin gas [60], modified Chaplygin gas (MCG) [61], barotropic fluids [26], logarithmic gas, etc. [13,14,16,18,19,32,33,62]. The increasing number and precision of cosmological experiments has revealed more evidence of the standard ΛCDM model, which is an accurate description of gravity on cosmological scales [63][64][65][66][67][68].…”

In this paper, we construct generic, spherically symmetric thin-shell wormholes and check their stabilities using the unified dark sector, including dark energy and dark matter. We give a master equation, from which one can recover, as a special case, other stability solutions for generic spherically symmetric thin-shell wormholes. In this context, we consider a particular solution; namely we construct an effective thin-shell wormhole under Lorentz symmetry breaking. We explore stability analyses using different models of the modified Chaplygin gas with constraints from cosmological observations such as seventh-year full Wilkinson microwave anisotropy probe data points, type Ia supernovae, and baryon acoustic oscillation. In all these models we find stable solutions by choosing suitable values for the parameters of the Lorentz symmetry breaking effect.
