Rotational dynamics. a Hij for a chain of N = 5 identical particles with D = 10 nm made of SiC, which are uniformly distributed with a center-to-center distance d = 1.5D. b Diagonal components of hij (blue) and the corresponding \(h_i^0\) (red). Notice the different scale. c Natural modes of the chain obtained by diagonalizing Hij and the corresponding decay rates. d–f Temporal evolution of the angular velocity of each particle in the chain for three different initial conditions
