Magnetic Wormholes and Vertex Operators
, 1994 We consider wormhole solutions in $2+1$ Euclidean dimensions. A duality transformation is introduced to derive a new action from magnetic wormhole action of Gupta, Hughes, Preskill and Wise. The classical solution is presented.

Dissolution and Flow Channeling in Hydrate‐Bearing Sediments: Implications for Permeability
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Estimates of in situ effective permeability of hydrate reservoirs are tens to hundreds of times less than most laboratory measurements on natural hydrate‐bearing sediments. The measured permeabilities are high because methane‐free water creates and expands flow channels in the sample during pressure core storage and laboratory testing.

Engineering Reports, Volume 8, Issue 1, January 2026.Proposed cyber physical system security framework. ABSTRACT The increasing adoption of cyber‐physical systems (CPS) in Industry 4.0 has heightened vulnerability to cyber threats. This study proposes a machine learning–based intrusion detection framework, DBID‐Net, to effectively identify and prevent attacks in CPS environments. The framework integrates

Thin-Shell Wormholes in Einstein and Einstein–Gauss–Bonnet Theories of Gravity
Universe, 2020 We review recent works on the possibility for eternal existence of thin-shell wormholes on Einstein and Einstein–Gauss–Bonnet gravity. We introduce thin-shell wormholes that are categorized into a class of traversable wormhole solutions.

Existence of stable wormholes on a noncommutative-geometric background in modified gravity
, 2017 In this paper, we discuss spherically symmetric wormhole solutions in $f(R,T)$ modified theory of gravity by introducing well-known non-commutative geometry in terms of Gaussian and Lorentizian distributions of string theory. For some analytic discussion,

Charged fermion in $(1+2)$-dimensional wormhole with axial magnetic field
, 2019 We investigate the effects of magnetic field on a charged fermion in a $(1+2)$-dimensional wormhole. Applying external magnetic field along the axis direction of the wormhole, the Dirac equation is set up and analytically solved in two scenarios ...

Replica Wormholes and Quantum Hair
Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract The recent applications of Euclidean path integrals to the black hole information problem are discussed. In calculations with replica wormholes as the next‐to‐leading order correction to the Gibbons–Hawking saddlepoint, the radiation density matrix approaches a pure state at late times, following the Page curve.

Exploring a novel Einstein–Rosen BTZ wormhole
European Physical Journal C: Particles and FieldsWe introduce a novel Einstein–Rosen BTZ wormhole metric as a solution to the Einstein field equations with a negative cosmological constant and explore in detail its various phenomenological aspects. We show that the wormhole metric is characterized by a
