• The 'extended Aharonov-Bohna (AB) period' recently pn'oposed by [K. Ktrsakabe and H. Aoki:J. Phys, Soc. Jpn. 65 (1996) 2772] is extensively stttdied nttnuerically for finite size systems ofstrongly correlated electrons. XVhi[e the extended AB period is the systena length tiznes the fltzxquantuun for noninteracting systems, we have fotrnd the existence of the botrndary across whichthe period is halved or another botrndary into an even shorter period on the phase diagr?tzn f'orthese models. If we conapare this result xvith the phase diagram predicted frorn the TounonagaLttttinger theory, devised for low-energy physics, the halved period (or shorter periods) laas aone-to-one correspondence to the existence of the pairing (phase separation or naetal-insulatortransition) in these rnodels. We have also found for the t-J model tlaat the extended AB perioddoes not change across the integrable-nonintegrabJe botrndary despite the totally different levelstatistics.
