@article{ISI:000228065400076, abstract = {We use the finite-size, density-matrix-renormalization-group (FSDMRG) method to obtain the phase diagram of the one-dimensional (d=1) extended Bose-Hubbard model for density rho=1 in the U-V plane, where U and V are, respectively, onsite and nearest-neighbor interactions. The phase diagram comprises three phases: superfluid (SF), Mott insulator (MI), and mass-density-wave (MDW). For small values of U and V, we get a reentrant SF-MI-SF phase transition. For intermediate values of interactions the SF phase is sandwiched between MI and MDW phases with continuous SF-MI and SF-MDW transitions. We show, by a detailed, finite-size scaling analysis, that the MI-SF transition is of Kosterlitz-Thouless (KT) type whereas the MDW-SF transition has both KT and two-dimensional Ising characters. For large values of U and V we get a direct, first-order, MI-MDW transition. The MI-SF, MDW-SF, and MI-MDW phase boundaries join at a bicritical point at (U,V)=(8.5 +/- 0.05,4.75 +/- 0.05).}, article-number = {104508}, author = {Pai, RV and Pandit, R}, doi = {10.1103/PhysRevB.71.104508}, eissn = {2469-9969}, issn = {2469-9950}, journal = {PHYSICAL REVIEW B}, month = {MAR}, number = {10}, times-cited = {25}, title = {Superfluid, Mott-insulator, and mass-density-wave phases in the one-dimensional extended Bose-Hubbard model}, unique-id = {ISI:000228065400076}, volume = {71}, year = {2005} }
