| Summary: | <p>Abstract</p><p>The retarded Green’s function (<it>E</it>−<it>H</it> + iε)<sup>−1</sup>is given for a dimensionally hybrid Hamiltonian which interpolates between one and two dimensions. This is used as a model for dimensional competition in propagation effects in the presence of one-dimensional subsystems on a surface. The presence of a quantum wire generates additional exponential terms in the Green’s function. The result shows how the location of the one-dimensional subsystem affects propagation of particles.</p> |
