Entangled Gravity: A New Path to Primordial Wave Detection
![The study demonstrates that as [latex] \lambda k(s) [/latex] approaches 0.5 - specifically transitioning from 0.1, 0.3 to 0.49 and 0.499 - the uncertainty product [latex] \Delta q \Delta_{q} [/latex] exhibits a critical behavior, suggesting a fundamental limit to precision even before accounting for slow-roll corrections.](https://arxiv.org/html/2602.20734v1/x2.png)
A novel theoretical framework suggests that quantum entanglement between hidden gravitational sectors could amplify primordial gravitational waves, offering a potential solution to longstanding constraints on early universe cosmology.




![Altermagnetic textures give rise to emergent spin-orbit coupling and odd-parity magnetism, demonstrated by the vanishing of an emergent Zeeman field [latex]V\_z \propto \cos 2\varphi[/latex] at specific points within circular Néel domain walls-where energy splitting stems solely from a metric-induced term [latex]\boldsymbol{\mathtt{g}}\_{\boldsymbol{p}}\propto\boldsymbol{p}\cdot\nabla\phi[/latex]-and, conversely, by the elimination of nodes in the energy contours of skyrmion textures due to contributions from both [latex]\nabla\theta[/latex] and [latex]\sin\theta\nabla\phi[/latex].](https://arxiv.org/html/2602.20236v1/x5.png)
