FINDING: Five-fold rotational symmetry is forbidden in periodic lattices but emerges in quasicrystals via aperiodic tiling governed by the golden ratio. MATH: Golden ratio φ = (1+√5)/2 ≈ 1.618; its reciprocal φ⁻¹ ≈ 0.618; complex golden ratio ζ = e^(iπ/5) = φ/2 + i√(3-φ)/2 (a 5th root of unity). Pe…

This chapter reviews thermal boundary resistance and conductance at metal–metal interfaces, with emphasis on cryogenic and sub-Kelvin temperatures. Thermal boundary resistance causes a temperature discontinuity at interfaces due to limited real contact area, leading to high local heat flux. While t…
