Abstract
Ringholes are space-time tunnelings connecting two asymptotically flat regions by means of a throat with the topology of a torus. This report considers the processes of semiclassical thermal emission from ringholes. It is shown that at or near the throat the ringholes can be characterized as a mixture of two thermal sources, one at positive temperature and the other at negative temperature which, respectively, emit usual black body radiation and phantom-like radiation, leading to two possible limiting situations, one similar to a wormhole in that it behaves just like a diverging lens, and the other similar to a black hole in that it behaves only as a converging lens.
