Cracking the Code: How Attackers Scale Up to Bypass AI Safety
![The study demonstrates that jailbreak success against Llama-3.1-8B-Instruct exhibits diminishing returns with increased attack compute (measured in FLOPs), following a saturating exponential relationship formalized in [latex]Eq.

Taming the Electron-Phonon Beast
![For an 8-site, 8-electron system, a density matrix renormalization group (DMRG) and functional-renormalization-based embedding method accurately trace the ground state energy across weak and strong coupling regimes, with observed deviations at low [latex]U[/latex] and high [latex]g[/latex] attributable to mean-field overstabilization of charge density wave order-an effect that dissipates within the Mott insulating phase.](https://arxiv.org/html/2603.11463v1/x5.png)
