The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Both perturbative calculations and numerical Monte Carlo simulations suggest a qualitative change in several scaling properties of the buckling transition. The critical compressional strain for thermal buckling now increases with system size... thermal buckling is controlled by a new fixed point with different critical exponents compared to classical Euler buckling.

C2weakest assumption

The polymer is treated as an extensible worm-like chain whose bending and stretching modes couple nonlinearly under fixed end-to-end strain, with thermal fluctuations treated perturbatively around the Euler state.

C3one line summary

Thermal fluctuations in extensible semiflexible polymers produce a buckling transition whose critical compressional strain increases with system size and is controlled by a new renormalization-group fixed point with altered exponents.
