Witrynacube-root dispersion around the singularity, a sublattice sym-metry forces it to have a square-root dispersion [37], which is indeed found to be the case here. We also find that the way the eigenvectors coalesce with one another depends on the path chosen to approach the EP 3 (while a regular EP 3 has three eigenvectors collapsing together … http://www.ece.uah.edu/courses/ee448/appen4_2.pdf

We investigate the topological skin effect in a ring resonator array which can be mapped into the square root of a Su-Schrieffer-Heeger (SSH) model with non-Hermitian asymmetric coupling ...

It is further noted that convergence to the unique positive-definite Hermitian matrix inverse square root of K is guaranteed, if the iterations start from an initial matrix, Q₀, that is a sufficiently small scalar multiple of the identity matrix, I: Q₀=aI. shuttle phoenix to prescott
