Some novel TWO-body effects analogous to the well-known THREE-body EfimovView original: http://arxiv.org/abs/1201.6014
effect are predicted. In the systems considered, particle A is constrained on a
TRUNCATED or BENT one-dimensional line or two-dimensional plane, or on one side
of a flat mirror in three dimensions (3D). The constraining potential is
fine-tuned such that particle A's ground state wave function is a constant in
the region in which it is constrained. Particle B moves in 3D and interacts
with particle A resonantly. An infinite sequence of giant two-body bound states
are found in each case.
