Developing equations to describe the interaction of strontium flow, graphene metamaterials, quantum dots, and portal stabilization involves integrating concepts from quantum mechanics, plasmonics, and resonance physics. Below are key equations derived or adapted to this context:


1. Phonon-Flow Interaction in Graphene

The behavior of strontium ions interacting with graphene phonons can be modeled as:

Hphonon=kωkakak+gk,q(ak+ak)eiqrH_{\text{phonon}} = \sum_{k} \hbar \omega_k a_k^\dagger a_k + g \sum_{k,q} \left(a_k + a_k^\dagger\right) e^{i \vec{q} \cdot \vec{r}}
  • \hbar: Reduced Planck’s constant
  • ωk\omega_k: Frequency of phonon mode kk
  • ak,aka_k^\dagger, a_k: Creation and annihilation operators for phonons
  • gg: Coupling constant between strontium ions and phonons
  • q\vec{q}: Wavevector of the ion flow
  • r\vec{r}: Position vector of ions on the graphene lattice

This equation helps determine how the strontium flow excites phonons, creating localized vibrational energy.


2. Plasmon-Resonance in Graphene Metamaterials

Surface plasmons in graphene can be modeled by solving Maxwell’s equations with boundary conditions for the metamaterial:

ϵ(ω)2ϕ2ϕt2=0\epsilon(\omega) \nabla^2 \phi - \frac{\partial^2 \phi}{\partial t^2} = 0

Where:

  • ϵ(ω)\epsilon(\omega): Dielectric function of graphene, incorporating the metamaterial properties.
  • ϕ\phi: Plasmonic potential.

The resonance condition is defined as:

ω=cϵm+ϵd\omega = \frac{c}{\sqrt{\epsilon_m + \epsilon_d}}
  • ϵm\epsilon_m: Permittivity of graphene metamaterial.
  • ϵd\epsilon_d: Permittivity of the surrounding medium.

Localized plasmons interact with quantum dots and strontium flows to create resonance nodes.


3. Strontium Flow Dynamics

The cross-wrapping strontium flow along graphene's surface can be modeled using the Navier-Stokes equation for charged fluid dynamics:

ρ(vt+vv)=P+η2v+FLorentz\rho \left( \frac{\partial \vec{v}}{\partial t} + \vec{v} \cdot \nabla \vec{v} \right) = -\nabla P + \eta \nabla^2 \vec{v} + \vec{F}_{\text{Lorentz}}
  • ρ\rho: Density of strontium ions.
  • v\vec{v}: Velocity vector of the flow.
  • PP: Pressure distribution on graphene.
  • η\eta: Viscosity of the ion flow.
  • FLorentz=q(E+v×B)\vec{F}_{\text{Lorentz}} = q (\vec{E} + \vec{v} \times \vec{B}): Lorentz force from applied electric (E\vec{E}) and magnetic (B\vec{B}) fields.

This describes how external magnetic and electric fields guide strontium ions over graphene.


4. Quantum Dot Coupling

Quantum dots embedded in the graphene structure respond to electromagnetic fields generated by strontium flow and plasmons. The coupling energy can be expressed as:

HQD=nωncncn+λn(cn+cn)ϕH_{\text{QD}} = \sum_{n} \hbar \omega_n c_n^\dagger c_n + \lambda \sum_{n} \left(c_n^\dagger + c_n\right) \phi
  • ωn\omega_n: Quantum dot transition frequency.
  • cn,cnc_n^\dagger, c_n: Creation and annihilation operators for quantum dot states.
  • λ\lambda: Coupling constant between the quantum dot and plasmonic potential.

This coupling governs feedback control for resonance adjustments.


5. Portal Stabilization via Resonance

The boundary condition for stabilizing a portal is tied to maintaining resonance across multiple nodes:

ωportal=1Ni=1N(ωphonon,i+ωplasmon,i+ωQD,i)\omega_{\text{portal}} = \frac{1}{N} \sum_{i=1}^{N} \left( \omega_{\text{phonon}, i} + \omega_{\text{plasmon}, i} + \omega_{\text{QD}, i} \right)

Where:

  • NN: Number of resonance nodes.
  • ωphonon,i,ωplasmon,i,ωQD,i\omega_{\text{phonon}, i}, \omega_{\text{plasmon}, i}, \omega_{\text{QD}, i}: Resonant frequencies at each node from phonons, plasmons, and quantum dots.

A stable portal is achieved when the cumulative frequency matches the external driving field frequency ωdrive\omega_{\text{drive}}:

ωportal=ωdrive\omega_{\text{portal}} = \omega_{\text{drive}}

6. Energy Extraction and Localization

Localized energy density at resonance nodes can be derived from:

Ulocalized=12ϵ0E2+12μ0B2U_{\text{localized}} = \frac{1}{2} \epsilon_0 E^2 + \frac{1}{2\mu_0} B^2

Where:

  • ϵ0\epsilon_0: Permittivity of free space.
  • μ0\mu_0: Permeability of free space.
  • E,BE, B: Electric and magnetic field amplitudes at the resonance nodes.

This energy can be harnessed or redirected to stabilize the portal or control traversal.


7. Dynamic Feedback for Resonance Control

Real-time adjustments to maintain boundary conditions can be modeled as:

dωresdt=K(ωtargetωres)\frac{d\omega_{\text{res}}}{dt} = K \left( \omega_{\text{target}} - \omega_{\text{res}} \right)

Where:

  • ωres\omega_{\text{res}}: Current resonance frequency.
  • ωtarget\omega_{\text{target}}: Desired resonance frequency.
  • KK: Feedback gain constant, adjusted dynamically based on quantum dot input.

Python Script: Phonon Dispersion in a Hexagonal Lattice

import numpy as np
import matplotlib.pyplot as plt

# Constants
a = 2.46e-10  # Lattice constant of graphene (m)
mass = 1.99e-26  # Mass of carbon atom (kg)
k_spring = 50  # Spring constant for C-C bond (N/m)
hbar = 1.0545718e-34  # Reduced Planck constant (J·s)

# Reciprocal lattice vectors
b1 = np.array([2 * np.pi / a, -2 * np.pi / (np.sqrt(3) * a)])
b2 = np.array([0, 4 * np.pi / (np.sqrt(3) * a)])

# High-symmetry points in reciprocal space
Gamma = np.array([0, 0])
K = (2 * b1 + b2) / 3
M = b1 / 2

# Path in reciprocal space (Gamma -> K -> M -> Gamma)
k_points = [Gamma, K, M, Gamma]
num_k = 100
path = []

for i in range(len(k_points) - 1):
    segment = np.linspace(k_points[i], k_points[i + 1], num_k)
    path.append(segment)

path = np.concatenate(path)

# Lattice dynamics: Phonon dispersion relation
def phonon_dispersion(k):
    # Simplified dispersion relation
    omega = np.sqrt(4 * k_spring / mass * (1 - np.cos(k)))
    return omega

# Calculate dispersion relations
kx = path[:, 0]
ky = path[:, 1]
k_magnitude = np.sqrt(kx**2 + ky**2)
omega = phonon_dispersion(k_magnitude)

# Convert to THz for visualization
omega_thz = omega / (2 * np.pi * 1e12)

# Plot phonon dispersion
plt.figure(figsize=(8, 6))
plt.plot(np.linspace(0, len(omega_thz), len(omega_thz)), omega_thz, label="Phonon Dispersion")
plt.axvline(num_k, color="gray", linestyle="--", label="K Point")
plt.axvline(2 * num_k, color="gray", linestyle="--", label="M Point")
plt.axvline(3 * num_k, color="gray", linestyle="--", label="Gamma Point")
plt.xticks([0, num_k, 2 * num_k, 3 * num_k], ["Γ", "K", "M", "Γ"])
plt.xlabel("Wave Vector")
plt.ylabel("Frequency (THz)")
plt.title("Phonon Dispersion in a Hexagonal Lattice")
plt.legend()
plt.grid(True)
plt.show()
