Nadya Tolokonnikova,

when the police started shutting down the streets around the art museum.
Police helicopters hovered overhead. Somewhere, through a loudspeaker, an officer delivered a tinny order to disperse.
Tolokonnikova was only three and a half days into what was supposed to be a
“durational performance” reenacting her two ye…

Wormhole Solutions and pre-inflationary in $F(R, T)$ Gravity with Axion Fields
In this study, we investigate wormhole solutions and inflationary initial conditions in the coupled axion-inflaton/scalar field system within $F(R,T)$ gravity. Notably, the Euclidean action is reduced by approximately $10^5$ compared with the GR case. In Euclidean AdS spacetime, we construct Euclidean (semi-)wormhole geometries that naturally set inflationary initial conditions. To enhance the probability of sustained inflation and address the short inflation duration issue in the no-boundary p…

A Study of Non-linear Flows and Shear Banding in Wormlike Micelles Under Varying Elasticity, Flow Curvature, and Surfactant Chemistry
We report the flow dynamics of two shear-banding wormlike micellar solutions with distinct surfactant chemistries in a Taylor-Couette (TC) setup following a startup shear. The solutions, formulated with CTAB/NaSal and CPyCl/NaSal, exhibit comparable bulk rheology and equilibrium microstructural properties. By varying the TC gap size, we systematically examine elasticity number over a range of 128000-4470000, while flow curvature spans from 0.022 to 0.171. Under a step shear into the stress plat…

A viable wormhole model in a five-dimensional spacetime
This paper generalizes two of the author's earlier wormhole solutions that are characterized by an extra spatial dimension. This paper adds the assumption that the components of the line element are functions not only of the radial coordinate $r$ but of the extra coordinate $l$ as well, resulting in a significant generalization. It is shown that the throat of the wormhole can be threaded with ordinary matter and that the unavoidable violation of the null energy condition can be attributed to th…

Pixie cat has been dusting behind the wardrobe.
She likes to go round there from time-to-time to check if there are any nesting birds. Because you never know. Ever the optimist.
It's a bit of a squeeze, and she comes out covered in dust. I have yet to determine how she manages to turn around. I suspect she uses a wormhole or something.

Quasinormal spectra of a wormhole family: overtone features and a parameter-controlled redshift
Though investigated extensively in the past, we take a detailed relook at the study of quasinormal modes (QNM) in a known family of wormholes (ultrastatic ($g_{00}=-1$), as well as spacetimes with different, non-constant $g_{00}$), which includes the familiar Bronnikov-Ellis spacetime as a special case. Our focus here is to go beyond the fundamental mode and obtain some of the QNM overtones using a suitable numerical scheme. Scalar and axial gravitational QNMs including two or three overtones a…

Study of Wormhole in $f(Q)$ gravity with some dark energy models
This study discusses the development of some particular static wormhole models in the background of an extended $f(Q)$ gravity theory. Wormhole solutions are derived by considering the radial pressure to admit an equation of state corresponding to Chaplygin gas. The Chaplygin gas equation of state is taken into consideration in two different forms: $p_{r}=-\frac{Bb(r)^{u}}{ρ^{a}}$, $p_{r}=-\frac{B}{ρ^{a}}$. Wormhole models are also generated assuming that a variable barotropic fluid may expla…
