关联电子模型中的有限尺度效应

章节摘录

版权页：   插图：   Summarizing, in this chapter we presented the calculation of finite-sizecorrections to characteristics of exactly solvable models of quantum spinsand correlated electrons with periodic and open boundary conditions, withand without inhomogeneities. We reminded the reader the main featuresof the description of critical phenomena and conformal field theory. Thelatter was used to calculate the asymptotic behaviour of low-energy corre-lation functions of considered models. Also, another finite-size effect, thebehaviour of persistent currents for periodic correlated electron chains isstudied. The calculation of finite size corrections for Bethe ansatz-solvable mod-els was pioneered in [de Vega and Woynarovich (1985)]. The reader canfind calculations of finite size corrections for quantum correlated chains,e.g., in [Woynarovich, Eckle and Truong (1989); Woynarovich (1989);Klümper, Batchelor and Pearce (1991); Pearce and Kliimper (1991);Kawakami and Yang (1991); Barley, Klümper, Schadschneider and Zittartz(1993); Bariev (1994)], homogeneous chains with periodic (twisted) bound-ary conditions, in [Alcaraz, Barber, Batchelor, Baxter and Quispel (1987);Asakawa and Suzuki (1995); Frahm and Zvyagin (1997a); Bediirftig andFrahm (1997)] for chains with open boundary conditions, see also [Frahmand Zvyagin (19975); Zvyagin (2002); Zvyagin (2003)] for quantum chainswith impurities. The dressed charge technique was introduced in [Korepin(1979)]. I can suggest the use of, e.g., the well-known books [Ma (1976);Cardy (1996); Kadanoff (2000); Sachdev (1999)] for the description of crit-ical phenomena in the vicinity of a phase transition. The scaling hy-pothesis was introduced in [Widom (1965a); Widom (19655)], see also[Rushbrooke (1963)], and developed in [Griffiths (1965); Kadanoff (1966);Josephson (1967a); Josephson (1967b); Fisher (1969)]. The conformal fieldtheory was pioneered in [Belavin, Polyakov and Zamolodchikov (1984)].
