“…Note that the role of quantum corrections on the stability of the wormhole is similar to the role played by a charge on the wormholes stability [8]. In the end we speculate that, if the origin of these quantum effects is related to the presence of dark matter and dark energy, as suggested by [30], the bottom line of this reasoning is that dark matter and dark energy may support the stability of the wormhole. …”

“…It is interesting to note that, in contrast to the ordinary Schwarzschild solution, these corrections leads to a non-zero components of the stress-energy tensor T μν . Moreover, according to [30], this may be a result of dark energy and dark matter. The outer horizon radius is calculated as…”

Recently, Ali and Khalil (Nucl Phys B, 909, 173-185, 2016), based on Bohmian quantum mechanics, derived a quantum corrected version of the Schwarzschild metric. In this paper, we construct a quantum corrected Schwarzschild thin-shell wormhole (QSTSW) and investigate the stability of this wormhole. First we compute the surface stress at the wormhole throat by applying the Darmois-Israel formalism to the modified Schwarzschild metric and show that exotic matter is required at the throat to keep the wormhole stable. We then study the stability analysis of the wormhole by considering phantom-energy for the exotic matter, generalized Chaplygin gas (GCG), and the linearized stability analysis. It is argued that quantum corrections can affect the stability domain of the wormhole.

“…This certainly invalidates the whole subsequent works [5,[10][11][12][13][14] that adopted the QRE approach and built on it. We believe that this QRE question needs to be fully addressed and settled before any further works based on QRE are contemplated.…”

We address the validity of the formalism and results presented in [ S. Das, Phys. Rev. D89 084068 (2014)] with regard to quantum Raychaudhuri equation. The author obtained the so called quantum Raychaudhuri equation by replacing classical geodesics with quantal trajectories arising from Bhommian mechanics. The resulting modified equation was used to draw some conclusions about the inevitability of focussing and the formation of conjugate points and therefore singularity. We show that the whole procedure is full of problematic points, on both physical relevancy and mathematical correctness. In particular, we illustrate the problems associated with the technical derivation of the so called quantum Raychaudhuri equation, as well as its invalid physical implications. The polar decomposition of the scalar field Φ is utilized as Φ = R exp iS and then using Bhom's interpretation to define new congruence with tangent vector field given byand consequently the norm of the velocity field u µ is given byform which the acceleration field follows asIf we compare this resultant acceleration with the corresponding one given in [1], we find a missing factor
