A bstract Quantum extremal islands reproduce the unitary Page curve of an evaporating black hole. This has been derived by including replica wormholes in gravitational path integral, but for transient, holes most relevant to Hawking’s paradox, these have not analyzed any detail. In this paper we study formed collapse Jackiw-Teitelboim gravity, and confirm that they lead island rule entropy. The...

A bstract We study the doubly holographic model of [1] in situation where a black hole two-dimensional JT gravity theory is coupled to an auxiliary bath system at arbitrary finite temperature. Depending on initial temperature relative temperature, can lose mass by emitting Hawking radiation, stay equilibrium with or gain absorbing thermal radiation from bath. In all these scenarios, unitary Pag...

using solvent evaporating and atomic emission spectrophotometric methods, the solubility of li2co3 in waterat 25°c was determined. comparing the value of thermodynamic solubility product constant, ksp(th),(ksp(tn) = exp(—ag.ss/rt)) of the mentioned salt to the value which is obtained from the observed solubility,shnoll-1 , and activity coefficients, f+ and f, which are estimated upon the extend...
