| Research Abstract |
The geometric phase is the most famous example of quantum holonomy, where an adiabatic cycle induces a nontrivial change for Examples of the quantum holonomy of exotic kind (also known as Cheon's anholonomies) have been found, where eigenenergies (or quasienergies) as well as eigenspaces of bound states exhibit multiple-valuedness in the parameter space. Through this research project, the theory of the exotic quantum holonomy has been further developed. Also, new examples of the exotic quantum holonomy have been found. Although the present results are purely theoretical, it is expected that the further study along this line will lead to the experimental realization of the exotic quantum holonomy.
