Matter–Antimatter Asymmetry in the DRUMS Framework
1. Symmetry at the Superfluid Level
At the fundamental level, DRUMS allows symmetric excitation modes corresponding to matter and antimatter:
\[
\Psi_{\pm} = \sqrt{\rho} e^{\pm i\theta}
\]
The \(+\) and \(-\) phase windings correspond to matter and antimatter states, respectively.
2. Substrate-Induced Symmetry Breaking
The cubic magnetic substrate introduces a directional bias in phase evolution due to anisotropic coupling:
\[
\Delta E = E_{+} - E_{-} \neq 0
\]
This arises because phase winding interacts differently with substrate orientation:
\[
E_{\pm} \sim \int \left( \frac{\hbar^2}{2m} |\nabla \theta|^2 \pm \alpha \, \mathbf{B}_{\rm sub} \cdot \nabla \theta \right) dV
\]
The coupling term \(\alpha \, \mathbf{B}_{\rm sub} \cdot \nabla \theta\) breaks symmetry between matter and antimatter.
3. Weak Interaction Asymmetry
Weak bosons couple to chiral modes of the superfluid:
\[
\mathcal{L}_{\rm weak} \sim g \, \bar{\Psi} \gamma^\mu (1 - \gamma^5) \Psi \, W_\mu
\]
In DRUMS, this chirality emerges from preferred rotational direction of vortex modes relative to the substrate.
As a result, decay rates differ:
\[
\Gamma_{matter} \neq \Gamma_{antimatter}
\]
4. Net Matter Production
Over cosmological time, the small energy difference leads to exponential amplification:
\[
\frac{dn}{dt} \sim -\Gamma_{ann} n^2 + \Delta \Gamma \, n
\]
Where \(\Delta \Gamma\) encodes asymmetry. Solution yields:
\[
n(t) \propto e^{\Delta \Gamma t}
\]
This naturally produces a matter-dominated universe.
5. Prediction
- CP violation parameters should correlate with measurable anisotropies in underlying field structure.
- Weak decay asymmetries should show directional dependence relative to large-scale structure.
- Analog superfluid systems with imposed lattice anisotropy should reproduce matter-antimatter imbalance.
6. Conclusion
- Matter and antimatter begin as symmetric phase modes.
- Cubic substrate introduces a small but persistent energy asymmetry.
- This asymmetry propagates through weak interactions and decay channels.
- Over time, this produces the observed dominance of matter.
