Mapping the twist-angle disorder and Landau levels in magic-angle graphene

Nature, 2019
The recently discovered flat electronic bands and strongly correlated and superconducting phases in magic-angle twisted bilayer graphene (MATBG) 1 , 2 crucially depend on the interlayer twist angle, θ .

How “Magic” is a Magic Metal Cluster?

Physical Review Letters, 1996
The stability of a closed-shell metal cluster, Na{sub 8}, is studied in a variety of surroundings using {ital ab} {ital initio} molecular dynamics. On the insulating NaCl(001) surface, Na{sub 8} is magic; even at 600 K it retains its intrinsic structure. On the Na(110) surface it spontaneously collapses, forming an epitaxial adlayer.

Magic rectangles and modular magic rectangles

Journal of Statistical Planning and Inference, 1996
A magic \(( m, n)\) rectangle is an \(m\times n\) matrix with entries \(1,\dots, mn\) for which all the row sums are the same and all the column sums are the same. A modular magic \((m, n)\) rectangle is an \(m\times n\) matrix with entries \(1,\dots, mn\) for which all the row sums are congruent modulo \(mn\) and all the column sums are congruent ...
