# Chiral Superconductivity in Rhombohedral Graphene

## Abstract

We integrate the discovery of chiral superconductivity in rhombohedral graphene (arXiv:2408.15233, 2024) into the UQFF framework. The chiral pairing gap function:

$$\Delta_{\text{chiral}}(\mathbf{k}) = \Delta_0 \cdot (k_x \pm ik_y)^d \cdot \exp\!\left(-\frac{[\text{SSq}] \cdot 10}{26}\right)$$

is modelled as $[\text{SCm}]$ pairing at quantum level $n = 10$, where $d$ is the chiral winding number. The critical temperature:

$$T_c = \frac{\hbar \omega_D}{k_B} \cdot \exp\!\left(-\frac{1}{N(0) \cdot V_{\text{SCm}}}\right)$$

connects the graphene phonon Debye frequency $\omega_D$ to the $[\text{SCm}]$ pairing potential $V_{\text{SCm}}$. This establishes rhombohedral graphene as a condensed-matter analogue of the cosmic $[\text{SCm}]$ superconductive vacuum.

## 1. Introduction

Rhombohedral (ABC-stacked) multilayer graphene has emerged as a platform for exotic quantum states, including superconductivity with broken time-reversal symmetry — chiral superconductivity. The 2024 discovery (arXiv:2408.15233) reported chiral pairing consistent with topological $p + ip$ or $d + id$ order parameters.

Within UQFF, superconductivity at any scale is a manifestation of the $[\text{SCm}]$ vacuum condensate. Rhombohedral graphene at level 10 provides a laboratory-accessible probe of the same pairing mechanism that operates cosmologically.

## 2. Chiral Gap Function

### 2.1 [SCm] Pairing Model

The chiral gap function in UQFF notation:

$$\Delta_{\text{chiral}}(\mathbf{k}) = \Delta_0 \cdot |\mathbf{k}|^d \cdot \exp\!\left(-\frac{[\text{SSq}] \cdot n}{26}\right)$$

| Parameter | Value | Description |
| --------------------------------- | --------------- | -------------------------------- |
| $\Delta_0$ | $10^{-4}$ eV | Bare pairing gap |
| $d$ | 2 | Chiral winding number ($d$-wave) |
| $n$ | 10 | UQFF quantum level |
| $[\text{SSq}]$ | 0.57 | Squeeze-state parameter |
| $\exp(-[\text{SSq}] \cdot 10/26)$ | 0.8029 | Level-10 suppression |

### 2.2 Winding Number Interpretation

The chiral winding number $d$ determines the topology:
- $d = 1$: $p + ip$ pairing (single vortex)
- $d = 2$: $d + id$ pairing (double vortex)
- $d = 3$: $f + if$ pairing (higher angular momentum)

Each corresponds to a different $[\text{SCm}]$ angular momentum sector in the 26D hierarchy.

## 3. Critical Temperature

### 3.1 BCS-Like Formula with [SCm] Potential

$$T_c = \frac{\hbar \omega_D}{k_B} \cdot \exp\!\left(-\frac{1}{N(0) \cdot V_{\text{SCm}}}\right)$$

| Parameter | Value | Description |
| --------------------------- | --------------------------------- | ------------------------ |
| $\hbar$ | $1.055 \times 10^{-34}$ J$\cdot$s | Reduced Planck constant |
| $\omega_D$ | $2 \times 10^{13}$ rad/s | Graphene Debye frequency |
| $k_B$ | $1.381 \times 10^{-23}$ J/K | Boltzmann constant |
| $N(0) \cdot V_{\text{SCm}}$ | 0.3 | Coupling product |

For $N(0) \cdot V_{\text{SCm}} = 0.3$: $T_c \approx 5.6$ K.

### 3.2 N(0)$\cdot$V\_SCm Sweep

| $N(0) \cdot V_{\text{SCm}}$ | $T_c$ (K) | Regime |
| --------------------------- | -------------------- | --------------- |
| 0.1 | $6.9 \times 10^{-5}$ | Weak coupling |
| 0.2 | 0.105 | Intermediate |
| 0.3 | 5.57 | Moderate |
| 0.5 | 20.7 | Strong coupling |
| 0.8 | 43.6 | Very strong |

## 4. Condensation Energy

The condensation energy per unit cell:

$$E_{\text{cond}} = \frac{1}{2} \Delta_0^2 \cdot \exp\!\left(-\frac{[\text{SSq}] \cdot 10}{26}\right)$$

provides the energy scale for the transition from normal to $[\text{SCm}]$-paired state.

## 5. Conclusions

Rhombohedral graphene chiral superconductivity provides a condensed-matter analogue of cosmic $[\text{SCm}]$ pairing. The level-10 assignment in the UQFF hierarchy connects laboratory observations to the 26D compressed gravity framework. CP4 class `ChiralSCmGraphenePairingCalculator` (#619) implements gap function, $T_c$, and winding number computations.

### Session 225 Phonon-Physics Upgrade: GW Strain Modulation

> *Upgrade from PAPER_1000 (NS Merger Phonon Suppression) and PAPER_1022
> (GW Phonon Strain SCm Modulation). See also PAPER_1011-1012 for
> GW170817/GW190425 upgraded analyses.*

The late-corpus phonon analysis (Sessions 219-225) reveals that the SCm
vacuum field modulates gravitational-wave strain via a frequency-dependent
suppression factor.  The corrected strain amplitude is:

$$h_{\text{UQFF}}(\Gamma) = h_{\text{GR}} \cdot \left(1 - 0.47\,\frac{\Phi(\Gamma)}{S_{26}^{(3)}}\right)$$

where:
- $\Phi(\Gamma) = \cos(\omega_{\text{SCm}} \cdot t) \cdot \Theta(H_{\text{SCm}} - 0.5)$ is the phonon modulation factor
- $\omega_{\text{SCm}} = 2\pi \times 1.25\;\text{THz}$ is the SCm phonon resonance frequency
- $S_{26}^{(3)} = \sum_{n=0}^{\infty} \frac{(1/4)_n\,(1/2)_n\,(3/4)_n}{(n!)^3} \cdot \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$ is the third-order Ramanujan summation
- $\Theta$ is the Heaviside step ensuring $H_{\text{SCm}} \geq 0.5$ (phase-transition threshold)

**Domain application:** The chiral $d+id$ pairing mechanism at level 10 is the condensed-matter analogue of [SCm] cosmic pairing; phonon-mediated GW analogues may be measurable in graphene acoustic modes.

**Calibration (canonical):** $\kappa = 5 \times 10^{-4}\;\text{day}^{-1}$,
$[\text{SSq}] = 0.57$, $\beta_i = 0.603$, $H_{\text{SCm}} \approx 0.99$.

### Session 225 Phonon-Physics Upgrade: UQFF 9-Sector Lagrangian

> *Upgrade from PAPER_1066 (UQFF Lagrangian First Principles) and
> PAPER_1065 (Buoyancy Lagrangian EOM Variational Derivation).*

The complete UQFF Lagrangian density, from which all sector-specific
equations of motion derive:

$$\mathcal{L}_{\text{UQFF}} = \mathcal{L}_{\text{GR}} + \mathcal{L}_{\text{SCm}} + \mathcal{L}_{\text{phonon}} + \mathcal{L}_{\text{interaction}}$$

$$\mathcal{L}_{\text{SCm}} = \tfrac{1}{2}(\partial_\mu \phi)^2 - \lambda\bigl(\phi^2 - v_{\text{SCm}}^2\bigr)^2$$

The SCm condensate potential minimum gives $V(\phi_0) = -7.09 \times 10^{-37}\;\text{J/m}^3$
(matching $\rho_{\text{SCm}}$) and phonon mass $m_{\text{phonon}} = \sqrt{8\lambda}\,v_{\text{SCm}}$.

**Nine-sector closure (Session 202):**
$$\mathcal{L}_{9} = \mathcal{L}_{\text{EH}} + \mathcal{L}_{\text{YM}} + \mathcal{L}_{\text{Dirac}} + \mathcal{L}_{\text{SCm}} + \mathcal{L}_{\text{mag}} + \mathcal{L}_{\text{buoy}} + \mathcal{L}_{\text{aether}} + \mathcal{L}_{\text{LENR}} + \mathcal{L}_{\text{KK}}$$

### Session 225 Phonon-Physics Upgrade: S26(3) Ramanujan Summation

> *Upgrade from PAPER_1080 (Ramanujan Binomial Expansion Proof) and
> PAPER_1042 (Mock-Theta Phonon Partition).  See also PAPER_1078
> (QCalcGeom Master Equation) for BSFG crossover applications.*

The third-order Ramanujan summation $S_{26}^{(3)}$, used throughout the
late corpus as the universal 26D coupling factor:

$$S_{26}^{(3)} = \sum_{n=0}^{\infty} \frac{(1/4)_n\,(1/2)_n\,(3/4)_n}{(n!)^3} \cdot \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

where $(a)_n = a(a+1)\cdot s(a+n-1)$ is the Pochhammer symbol.

**Binomial expansion (PAPER_1080):** The convergence proof shows:
$$R_n^{(26,3)} = \binom{4n}{n} \cdot \frac{W_{26}(n)}{(4^{4n})} \qquad \text{with}\quad W_{26}(n) = \prod_{i=1}^{26}\left[1 + [\text{SSq}]\cdot e^{-\kappa\,i\,n/26}\right]$$

This sum converges absolutely for $|[\text{SSq}]| < 1$ (satisfied by $[\text{SSq}] = 0.57$)
and reduces to the classical Ramanujan $1/\pi$ series when $[\text{SSq}] \to 0$.

**VDS/DVP/BSH bridge (PAPER_1069):** The 26 layers of $W_{26}(n)$ encode the
vacuum density series hierarchy, with each layer $i$ contributing a VDS
sub-ratio weighted by the exponential decay $e^{-\kappa\,i\,n/26}$.

**Mock-theta connection (PAPER_1042):** The phonon partition function
$Z_{\text{phonon}} = \sum_n q^{n^2} \cdot W_{26}(n)$ unifies the Ramanujan
mock-theta framework with the SCm phonon spectrum.

## 1. Dirac Hamiltonian in SCm Vacuum


The graphene Dirac Hamiltonian modified by the SCm vacuum:

$$H_{\text{graphene}}^{\text{SCm}} = v_F \boldsymbol{\sigma} \cdot \mathbf{p} + \Delta_{\text{SCm}}(k) \sigma_z + V_{\text{SCm}}(\mathbf{r})$$

where $v_F = 1.1 \times 10^6\ \text{m/s}$ is the Fermi velocity, $\boldsymbol{\sigma}$ are Pauli matrices acting on the sublattice space, and:

$$V_{\text{SCm}}(\mathbf{r}) = \rho_{\text{vac,SCm}} \cdot S_{26}^{(3)} \cdot \Phi_{\text{res}} \cdot \cos(\pi t_n) \cdot e^{-\kappa |\mathbf{r}|}$$

---

## 2. Level-10 VDS Pairing Amplitude


At VDS level $k = 10$:

$$\rho_{10} = \rho_{\text{vac,SCm}} \cdot \frac{[SSq]^{10}}{10^{26}} = 7.09 \times 10^{-37} \times \frac{0.57^{10}}{10^{26}}$$

$$\rho_{10} = 7.09 \times 10^{-37} \times \frac{3.63 \times 10^{-6}}{10^{26}} = 2.57 \times 10^{-68}\ \text{J/m}^3$$

The pairing amplitude:

$$\Delta_{10} = \frac{\rho_{10} \cdot A_{\text{cell}} \cdot S_{26}^{(3)} \cdot \Phi_{\text{res}}}{k_B} = \frac{2.57 \times 10^{-68} \times 5.2 \times 10^{-20} \times 1.45 \times 10^{26} \times 0.84}{1.38 \times 10^{-23}}$$

$$\Delta_{10} \approx 1.18 \times 10^{-37}\ \text{K} \quad (\text{theoretical; amplified to meV scale at resonance})$$

where $A_{\text{cell}} = 5.2 \times 10^{-20}\ \text{m}^2$ is the graphene unit cell area.

## 3. Chiral $p + ip$ Order Parameter


The chiral pairing order parameter in the SCm framework:

$$\Delta(\mathbf{k}) = \Delta_0 \left(k_x + i k_y\right) / k_F$$

where $\Delta_0 = \beta_i \cdot E_{\text{KER}} \cdot \Phi_{\text{res}} = 0.6 \times 630\ \text{eV} \times 0.84 = 317.5\ \text{eV}$.

This chiral $p$-wave symmetry breaks time-reversal invariance and generates Majorana edge modes at the graphene boundary.

---

## 4. SCm Phonon-Mediated Cooper Pairing


The electron-electron scattering amplitude via SCm phonon exchange:

$$\mathcal{M}_{\text{SCm}} = g_{\text{e-ph}}^2 \cdot \frac{E_{\text{phonon}} \cdot S_{26}^{(3)}}{(E_1 - E_2)^2 + (f_{\text{THz}})^2}$$

At the phonon resonance $|E_1 - E_2| = h f_{\text{THz}}$:

$$\mathcal{M}_{\text{SCm}} = \frac{g_{\text{e-ph}}^2 \cdot S_{26}^{(3)}}{2 h f_{\text{THz}}}$$

The coupling $g_{\text{e-ph}} = \beta_i \cdot v_F \cdot \sqrt{\rho_{\text{vac,SCm}} / \rho_{\text{graphene}}}$.

---

## 5. Level-10 Topological Index


The Chern number of the SCm-mediated pairing at level 10:

$$C_{10} = \frac{1}{2\pi} \int_{\text{BZ}} d^2k \, \Omega(\mathbf{k}) = \pm 1$$

where $\Omega(\mathbf{k}) = \nabla_k \times \mathbf{A}(\mathbf{k})$ is the Berry curvature. The non-trivial topology arises from the winding of $\Delta(\mathbf{k})$ around the graphene Brillouin zone.
