Central role of exchange-correlation hole in the 2D metal-insulator | J.S. Thakur

31 Dec 1999 | Subject: | Strongly Correlated Electrons | cond-mat.str-el | Abstract: | We show that the metal to insulator transition, whether generated by decreasing the electron density or by increasing the spin alignment, is determined by a universal functional form of the two-electron correlation function g(r). This result provides direct evidence of the central role of the Coulomb repulsion and exchange in driving the metal-insulator transition. | Source: | arXiv, cond-mat/0001435 | Services: | Forum | Review | PDF | Favorites |
