Abstract
We describe how tightly confining magnetic waveguides for atoms
can be created with microfabricated or nanofabricated wires. Rubidium atoms
guided in the devices we have fabricated would have a transverse mode
energy spacing of 
K. We discuss the creation of a single-mode
waveguide for atom interferometry whose depth is comparable to
magneto-optical trap (MOT) temperatures. We also discuss the application of
microfabricated waveguides to low-dimensional systems of quantum degenerate
gases, and show that confinement can be strong enough to observe
fermionization in a strongly interacting bosonic ensemble.
