HIGHLIGHTS
- who: A. Ferraz from the a International Institute of Physics, UFRN, Department of Experimental and Theoretical Physics, UFRN, Natal, Brazil have published the research work: Effective action for strongly correlated electron systems, in the Journal: (JOURNAL)
- what: The work has actually been motivated by Shankar's contribution . The authors show that Shankar's effective action can indeed be derived from the su(2|1) path-integral representation of the partition function of the t-J model. As the authors show below the remaining integral in_(52) over the bosonic fields z̄k, zk precisely cancels . . .
