torsion noncommutative 1/2 spin nonlocal quantum black holes: Gerard 't Hooft wormhole metamaterial
Показать описание
Although that is a theoretical paper, the first steps were moved toward testing the laboratory realization of these scenarios by envisaging Gedankenexperiments on the interplay between an external electromagnetic field (to excite the particle–hole pair and realize the time loops) and a suitable distribution of dislocations described as torsion (responsible for the measurable holonomy in the time loop, hence a current). The general analysis establishes that we need to move to a nonlinear response regime. Then the authors conclude by pointing to recent results from the interaction of laser–graphene that could be used to look for manifestations of the torsion-induced holonomy of the time loop, e.g., as specific patterns of suppression/generation of higher harmonics. As said before, USUSY takes into account torsion and couples its fully antisymmetric component with fermions in a very natural way.
Therefore, it could play a significant role also in this exotic time loop [76]
Quoting Feynman and paraphrasing Bekenstein, those objects are called
“Xons” [ 2]. If such a view is correct, even matter that we deem to be fundamental, i.e., ele-
mentary, is in fact “quasi-matter”, just like the massless quasi-particles, ψ, of graphene [ 30 ]
that owe their properties to the interaction with the lattice1. The most noticeable result
of this “quasi-particle picture” [ 6] is that the evaporation of a BH inevitably leads to an
information loss, in the sense that, in general, there is a nonzero entanglement entropy asso-
ciated to the final products of the evaporation. On the other hand, within the same picture,
in [40], the authors describe BH evaporation from the point of view of the Xons. They see
there that the Bekenstein bound [ 3 –5 ] can be an effect of the Pauli exclusion principle, and
that a full unitary picture, leading to a complete recovering of the initial information, is
only possible if one could track the evolution of those fundamental constituents.

yes unless you realize that humans are originally spirit as coherent biophotons!!
"However, the results in this work show that the situation
changes for a fermionic matter content"
In our approach, the Dirac matter is described
by a quantum wave function rather than a quantum
field. This results in a more tractable model, with
the backreaction of the matter to spacetime geometry
being taken into account.
“From the outside perspective, travel through the wormhole is equivalent to quantum teleportation using entangled black holes,” Dr. Jafferis said.
"Finally, we discuss the possibility of producing
the condensed matter analogous of this wormhole in a graphene sheet and analyze the electronic transport through it."
∆t (without the wormhole, therefore) and the one that
it spends to travel the equivalent distance through the Casimir wormhole, ∆τ , both with the
Fermi velocity. The parameter ℓ = 2.46 ̊A is the lattice constant of the graphene. The graph
suggests that the presence of the wormhole in the sheet represents a vantage with respect
to the efficiency of the electronic transport throughout the material, better the smaller the
size of the throat.
microscopic wormholes seem less far-fetched than in previous theories.
As the physicists report in their study, it is the inclusion of the Dirac field into their model that permits the existence of a wormhole traversable by matter, provided that the ratio between the electric charge and the mass of the wormhole exceeds a certain limit.
When Dr. Goto and his colleagues performed a detailed analysis combining both the standard description and a wormhole picture, their result matched Page’s prediction, suggesting that physicists are right to suspect that information is preserved even after the black hole’s demise.
“But this raises new questions. We still don’t know the basic mechanism of how information is carried away by the radiation.
