Passage of radiation through wormholes of arbitrary shape
, 2010 We study quasinormal modes and scattering properties via calculation of the $S$-matrix for scalar and electromagnetic fields propagating in the background of spherically and axially symmetric, traversable Lorentzian wormholes of a generic shape.

A New Padé Approach to Modeling Wormholes in Dekel‐Zhao Dark Matter Halos
Annalen der Physik, Volume 538, Issue 3, March 2026.A matter‐first Padé strategy is introduced to build traversable wormholes from prescribed dark‐matter halos. Rational Padé fits approximately the Dekel–Zhao density and are analytically integrated to obtain a shape function that exactly reproduces the intended matter content, avoiding spurious poles of geometry‐first schemes.

Topologically Protected Wormholes in Type-III Weyl Semimetal Co3In2X2 (X = S, Se)
Condensed Matter, 2021 The observation of wormholes has proven to be difficult in the field of astrophysics. However, with the discovery of novel topological quantum materials, it is possible to observe astrophysical and particle physics effects in condensed matter physics. It

Estimating saturated hydraulic conductivity of soil samples from Kansas mesonet database
Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.Abstract In soil physics, saturated hydraulic conductivity, Ksat${{K}_{{\mathrm{sat}}}}$, is a key soil hydraulic parameter governing the movement of water and solutes, with broad implications for transport processes under variably saturated conditions. Its accurate estimation, however, is challenging and requires precise characterization of pore space.

, 2011 We construct the asymptotically flat charged thin-shell wormholes of Lovelock gravity in seven dimensions by cut-and-paste technique, and apply the generalized junction conditions in order to calculate the energy-momentum tensor of these wormholes on the

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract We investigate how mineral dissolution reshapes flow pathways and solute transport in three‐dimensional discrete fracture networks using a computationally efficient graph‐based reactive transport model. The DFNs are inspired by field‐site observations of fractured carbonate and represent realistic connectivity and structural heterogeneity ...

Half-wormholes in a supersymmetric SYK model
Journal of High Energy PhysicsWe identify half-wormhole contributions to the non averaged N $$ \mathcal{N} $$ = 1 supersymmetric SYK model in which time has been reduced to a point. As in previously studied examples, the inclusion of half-wormholes restores factorisation in the large

Sculpting Spacetime: Thin Shells in Wormhole Physics
UniverseIn this work, we employ the Darmois–Israel thin-shell formalism to construct both static and dynamic thin-shell configurations surrounding traversable wormholes.

On the stability of thin-shell wormholes in noncommutative geometry
, 2012 This paper reexamines a special class of thin-shell wormholes that are unstable in general relativity in the framework of noncommutative geometry.
