Approximate quantum cloaking and almost-trapped states.
Physical review letters, no. 22 (2008): 220404-220404
We describe potentials which act as approximate cloaks for matter waves. These potentials are derived from ideal cloaks for the conductivity and Helmholtz equations. At most energies E, if a potential is surrounded by an approximate cloak, then it becomes almost undetectable and unaltered by matter waves originating externally to the cloa...更多
