Gold density of states
Gold is the most malleable of all metals. It can be drawn into a wire of single-atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre (11 sq ft), and an avoirdupois ounce into 300 square feet (2… WebThousands of gold placer claims are maintained in every state, evidence that there is still gold to be discovered, and in many cases is being actively mined.

WebThe density of states is defined by ρ ( ε) = ∑ n ψ n ψ n δ ( ε − ε n), where ε n is the eigenvalue of the eigenstate ψ n . Inserting a complete orthonormal basis, this can be rewritten as ρ ( ε) = ∑ i ρ i ( ε), ρ i ( ε) = ∑ n ψ n i i ψ n δ ( ε − ε n) ρ ( ε) = ∫ d r ρ ( r, ε), ρ ( r, ε) = ∑ n ψ n r r ψ n δ ( ε − ε n)
