The energy of a graph is the sum of the moduli of the eigenvalues of its adjacency matrix. We study the energy of integral circulant graphs, also called gcd graphs. Such a graph can be characterized ...

Circulant matrices are a special class of structured matrices that underpin a diverse range of applications in mathematics and engineering. Characterised by the property that each row is a cyclic ...

Quantum state transfer on graphs encompasses the study of how quantum information, often stored as a state in a quantum system, can be reliably transmitted across interconnected networks modelled by ...
