A mixed graph is said to be integral if all the eigenvalues of its Hermitian adjacency matrix are integer. The mixed circulant graph Circ ( Z n , C ) is a mixed graph on the vertex set Z n and edge set { ( a, b ) : b − a ∈ C} , where 0 6∈ C . If C is closed under inverse, then Circ ( Z n , C ) is called a circulant graph . We express the eigenvalues of Circ ( Z n , C ) in terms of primitive n -th roots of unity, and find a sufficient condition for integrality of the eigenvalues of Circ ( Z n , C…

Which graphs have integral spectra
The spectrum S(G) of a graph G of order p is defined as the non-increasing sequence of the p real eigenvalues of the adjacency matrix of G. It has been found that certain graphs have an integral
4 - REGULAR INTEGRAL GRAPHS AVOIDING ±3 IN THE SPECTRUM
We determine all connected 4-regular integral graphs avoiding ±3 in the spectrum. There are exactly 16 bipartite and 8 nonbipartite such graphs. The smallest bipartite one is K4,4, while the largest
