Here, we investigate the stability, and the effect of different parameters on the stability, of a class of nonrotating thin-shell wormholes formed by nonrotating lower-dimensional non-linear electrodynamics regular black holes. We find that the event horizon radius shifts outward when the parameter

L

and the black hole charge are increased, as seen in the graph of the metric function (

G (r)

). This suggests that these factors significantly affect the location of the horizon. Furthermore, the black hole’s mass is critical; wormholes with larger masses are more stable, whereas wormholes with smaller masses have smaller stability zones. As the equation of state parameter varies across multiple values, more research reveals the effect of diverse matter compositions on the stability of nonrotating thin-shell wormholes. We identify stable configurations with a concave-up potential function for configurations where

χ > - 1 / 3

. On the other hand, dark energy configurations (

χ < - 1 / 3

) are stable as well, whereas phantom energy configurations (

χ < - 1

) cause instability with a concave-down potential. An examination of generalized Chaplygin gas reveals that specific kinds of matter can cause wormhole structures to become unstable. This sheds light on the intricate yet vital connection between the state equations and the stability of thin-shell wormholes, which can direct subsequent theoretical investigations in spacetime physics.

Stellar isotropic model in the symmetric teleparallel equivalent of general relativity theory

Recently, the theory of symmetric teleparallel equivalent of general relativity (STEGR) has gained much interest in the cosmology and astrophysics community. Within this theory, we discuss the method of deriving a stellar isotropic model. In this respect, we implement the equations of motion of STEGR theory to a spacetime that is symmetric in a spherical manner, resulting in a set of nonlinear differential equations with more unknowns than equations. To solve this issue, we assume a special form of

g_{t t}

, and suppose a null value of the anisotropy to obtain the form of

g_{r r}

. We then investigate the possibility of obtaining an isotropic stellar model consistent with observational data. To test the stability of our model, we apply the adiabatic index and the Tolman–Oppenheimer–Volkoff equation. Furthermore, we examine our model using different observed values of radii and masses of pulsars, showing that all of them fit in a consistent way.

This paper examines charged wormhole models within

f (R, L_{m})

gravity, supported by anisotropic energy–momentum tensors and Maxwell fields. The wormhole geometry is shaped by dark matter halo profiles, including the Universal Rotation Curve (URC), Navarro–Frenk–White (NFW), and Scalar Field Dark Matter (SFDM) models, assuming a constant redshift function. Using the

f (R, L_{m}) = \frac{R}{2} + L_{m}^{n}

model, shape functions are derived by correlating the energy densities of dark matter halo profiles with those predicted by

f (R, L_{m})

gravity. The null energy condition (NEC) is analyzed at the wormhole throat,

r = r_{0}

, demonstrating specific parameter regimes where the NEC is violated. Stability is assessed through the equilibrium of hydrostatic and anisotropic forces, which cancel each other. The volume integral quantifier (VIQ) is utilized to evaluate the distribution of exotic matter near the throat, offering a detailed understanding of its role in stabilizing the wormhole. Finally, embedding diagrams are presented to illustrate the wormhole geometry, providing a visual representation of its spatial structure.

Bose-Bose gases with nonuniversal corrections to the interactions: A droplet phase

Through an effective quantum field theory within Bogoliubov’s framework and taking into account nonuniversal effects of the interatomic potential we analytically derive the leading Gaussian zero- and finite-temperature corrections to the equation of state of ultracold interacting Bose-Bose gases. We calculate the ground-state energy per particle at zero and low temperature for three- two- and one-dimensional two-component bosonic gases. By tuning the nonuniversal contribution to the interactions we address and establish conditions under which the formation and stability of a self-bound liquidlike phase or droplet with nonuniversal corrections to the interactions (DNUC) is favorable. At zero temperature in three-dimensions and considering the nonuniversal corrections to the attractive interactions as a fitting parameter the energy per particle for DNUC is in good agreement with some diffusion Monte Carlo results. In two dimensions the DNUC present small deviations regarding conventional droplets. For the one-dimensional DNUC the handling of the nonuniversal effects to the interactions achieves a qualitative agreement with the trend of some available Monte Carlo data in usual droplets. We also introduce some improved Gross–Pitaevskii equations to describe self-trapped DNUC in three, two and one dimension. We briefly discuss some aspects at low temperature regarding nonuniversal corrections to the interactions in Bose-Bose gases. We derive the dependencies on the nonuniversal contribution to the interactions but also on the difference between intra- and inter-species coupling constants. This last dependence crucially affect the three- and the two-dimensional DNUC driving thus to a thermal-induced instability. This thermal instability is also present in one-dimensional Bose-Bose gases, but it is not relevant on the formation of DNUC. This is explained because the necessary attraction mechanism to achieve this phase naturally arises in the fluctuations at zero temperature without major restrictions as it happens in the other dimensions.

Mechanisms behind the Aschenbach effect in non-rotating black hole spacetime

General relativity predicts that a rotating black hole drags the spacetime due to its spin. This effect can influence the motion of nearby objects, causing them to either fall into the black hole or orbit around it. In classical Newtonian mechanics, as the radius (r) of the orbit increases, the angular velocity (

Ω

) of an object in a stable circular orbit decreases. However, Aschenbach discovered that for a hypothetical non-rotating observer, contrary to usual behavior, the angular velocity increases with radius in certain regions (Aschenbach, 2004). Although the possibility of observing rare and less probable ”rotational” behaviors in a rotating structure is not unlikely or impossible. However, observing such behaviors in a “static” structure is not only intriguing but also thought-provoking, as it raises questions about the factors that might play a role in such phenomena. In seeking answers to this question, various static models, particularly in the context of nonlinear fields, were examined, with some results presented as examples in the article. Among the models studied, the model of Magnetic Black Holes in 4D Einstein–Gauss–Bonnet Massive Gravity Coupled to Nonlinear Electrodynamics (M-EGB-Massive) appears to be a candidate for this phenomenon. In the analysis section, we will discuss the commonalities of this model with previous models that have exhibited this phenomenon and examine the cause of this phenomenon. Finally, we will state whether this phenomenon is observable in other black holes and, if not, why.

Universal behaviors of dynamical quantum transition in trapped large spin fermions

Dynamical universality in far-from-equilibrium quantum systems has already attracted significant attention. We have performed a systematic study on the long-time spin-mixing dynamics of harmonically trapped spin-

3 / 2

Fermi gases by solving the time-dependent Hartree–Fock equations. Our findings reveal that the evolution process goes through two distinct stages, both of which exhibit interesting universal behaviors. In the beginning, the so-called giant oscillation is observed, with the amplitude damping in a universal power-law,

A (t) = A_{0} - γ t^{α}

, where the exponent

α

remains constant regardless of the particle number and interaction strength. Then a revival-like phenomenon appears in the long-time stage, with the oscillation amplitude increasing suddenly and soon decreasing again. Differently, the damping seems in an exponential-law,

A (t^{'}) = A_{0}^{'} + k {exp}^{- β t^{'}}

, where the parameter

β

depends on both the particle number and interaction strength. Such difference indicates that the second stage is not a simple revival of the first one, which implies that a dynamical quantum transition occurs between the two stages.
