Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The d-wave superconductivity (dSC) and antiferromagnetism are analytically studied in a renormalized mean-field theory for a two-dimensional t-J model plus an on-site repulsive Hubbard interaction U. The purpose of introducing the U term is to partially impose the no-double-occupancy constraint by employing the Gutzwiller approximation. The phase diagrams as functions of doping δ and U are studied. Using the standard value of t /J=3.0 and in the large-U limit, we show that the antiferromagnetic (AF) order emerges and coexists with the dSC in the underdoped region below the doping δ∼0.1. The dSC order parameter increases from zero as the doping increases and reaches a maximum near the optimal doping δ∼0.15. In the small-U limit, only the dSC order survives while the AF order disappears. As U increases up to a critical value, the AF order shows up and coexists with the dSC in the underdoped regime. At half-filling, the system is in the dSC state for small U and becomes an AF insulator for large U. Within the present mean-field approach, we show that the ground-state energy of the coexistent state is always lower than that of the pure dSC state. ©2005 The American Physical Society.
