WebAny Hamiltonian matrix with a finite dimension has a discrete spectrum. So all the physical systems (or all the Hamiltonian) are gapped. Certainly, the above is not what we mean by "gapped Hamiltonian" in physics. But what does it mean for a Hamiltonian to be gapped? WebTools. A Hamiltonian cycle around a network of six vertices. In the mathematical field of graph theory, a Hamiltonian path (or traceable path) is a path in an undirected or directed graph that visits each vertex …
