Defect Wormholes Are Defective
Universe, 2023 The various “defect wormholes” developed by Klinkhamer have recently attracted considerable attention—especially in view of the fact that the simplest example, the so-called “vacuum defect wormhole”, was claimed to be an everywhere-vacuum everywhere ...

Energy conditions and cosmic acceleration [PDF]
Physical Review D, 2007 In general relativity, the energy conditions are invoked to restrict general energy-momentum tensors $T_{μν}$ in different frameworks, and to derive general results that hold in a variety of general contexts on physical grounds. We show that in the standard Friedmann-Lemaitre-Robertson-Walker (FLRW) approach, where the equation of state of the ...

Nanocomposites, 2023 In this work, Ni-W/diamond composite alloy coatings were successfully fabricated on low carbon steel by using direct current (DC) electrodeposition. The Ni-W molar ratio was varied in the range of 0.22–2 in the plating bath. The effect of variation of Ni-

Energy conditions for an imperfect fluid
Classical and Quantum Gravity, 1988 The authors investigated energy conditions of a viscous fluid with heat flow energy moment tensor. They considered Segre type [111, 1], [11, 2] and their degeneracies. Their main results are in the form of general theorems to help as a guide for testing energy conditions of imperfect fluids.

Derivation of the null energy condition
Physical Review D, 2015 We derive the null energy condition, understood as a constraint on the Einstein-frame Ricci tensor, from worldsheet string theory. For a closed bosonic string propagating in a curved geometry, the spacetime interpretation of the Virasoro constraint condition is precisely the null energy condition, to leading nontrivial order in the alpha-prime ...
