Twisted Light in Exotic Materials: Unveiling Chiral Graviton Modes
![The calculated graviton spectrum, examined across varying bond dimensions for both [latex]S=+2[/latex] and [latex]S=-2[/latex] sectors with an interaction strength of [latex]V_{AB}=0.71[/latex] on a [latex]N=2N_{x}N_{y}[/latex] system-where [latex]N_{x}=24[/latex] and [latex]N_{y}=3[/latex]-demonstrates a stable and increasingly prominent chiral graviton mode, achieved with parameters [latex]\eta=0.05[/latex] and [latex]T=100[/latex].](https://arxiv.org/html/2601.05196v1/x6.png)
New research reveals the existence of stable, chiral gravitational waves within a unique class of quantum materials, bridging theoretical predictions with potential experimental observation.





![The Regge-pole spectrum of a Schwarzschild black hole, when perturbed, exhibits a migration pattern reminiscent of Nariai spacetime, where increasing perturbation strength causes most poles to shift towards lower real values, while select poles diverge, creating bifurcated trajectories that are attracted to or repelled from specific points-a dynamic governed by integral curves and reflecting the system’s inherent instability as described by [latex]Eq.
