Implementation Considerations

• Requires expertise in nanotube handling, vacuum sealing, and high-temperature material processing under inert atmosphere.
• Dependent on tunable laser systems, vibrationally isolated spectrometers, and precision optical components (VBG, half-wave plates).
• Necessitates cross-team standardization of sample loading, laser power calibration, and temperature control protocols.
• Adaptation across model systems requires re-optimization of photon excitation energy to match van Hove singularities in 1D density of states.
• Practical limitation: Signal saturation at high laser power necessitates careful power modulation to maintain linear response regime.
