U. Leonhardt, Comment on "Aharonov-Bohm scattering of neutral atoms with induced electric dipole moments" by J. Audretsch and V.D. Skarzhinsky, PHYS LETT A, 253(5-6), 1999, pp. 370-372
Audretsch and Skarzhinsky [Phys. Lett. A 241 (1998) 7] use standard scatter
ing theory in Aharonov-Bohm (AB) type situations. However, the long-range c
haracter of AB interactions leads to severe mathematical problems that call
for an appropriate modification of scattering theory [U. Leonhardt, M. Wil
kens, Europhys. Lett. 42 (1998) 365]. Furthermore, in their paper absorptio
n is treated in an inconsistent way. (C) 1999 Elsevier Science B.V.
