Abstract The behavior of persistent current in a mesoscopic cylinder threaded by an Aharonov–Bohm flux ϕ is carefully investigated within a Hartree–Fock mean field approach. We examine the combined effect of second‐neighbor hopping integral and Hubbard correlation on the enhancement of persistent current in presence of disorder. A significant change in current amplitude is observed compared to the traditional nearest‐neighbor hopping model and the current amplitude becomes quite comparable to experimental realizations. Our analysis is found to exhibit several interesting results which have so far remained unaddressed.
