Recent studies have shown that (a) quantum effects may be sufficient tosupport a wormhole throat and (b) the total amount of "exotic matter" can bemade arbitrarily small. Unfortunately, using only small amounts of exoticmatter may result in a wormhole that flares out too slowly to be traversable ina reasonable length of time. Combined with the Ford-Roman constraints, thewormhole may also come close to having an event horizon at the throat. Thispaper examines a model that overcomes these difficulties, while satisfying theusual traversability conditions. This model also confirms that the total amountof exotic matter can indeed be made arbitrarily small.Comment: 8 pages, AMSTe

Can a wormhole supported by only small amounts of exotic matter really be traversable?
