A. Kamenev et al., CONDUCTANCE OF AHARONOV-BOHM RINGS - FROM THE DISCRETE TO THE CONTINUOUS-SPECTRUM LIMIT, Europhysics letters, 28(6), 1994, pp. 391-396
The average dissipative conductance of an array of mesoscopic rings, s
ubject to an a.c. magnetic flux, is investigated. The magnitude and si
gn of the magnetoconductance is found to depend on the statistical ens
emble (canonical or grand-canonical), the temperature and inelastic le
vel broadening.
