Abstract

• We study the competition of antiferromagnetism and d-wave superconductivity at zero temperature in the two-dimensional Hubbard model using cellular dynamical mean-field theory for a 2x2 plaquette, and solve the associated cluster impurity model at zero temperature by means of exact diagonalization. The interplay between the two phases depends strongly on the strength of the correlation. At strong coupling (U greater than or similar to 8t) the two phases do not mix, and a first-order transition takes place as a function of doping between two pure phases. At weak coupling (U less than or similar to 8t) the two order parameters coexist within the same solution in a range of doping and the system smoothly evolves from the antiferromagnet to the superconductor. When the transition between the superconducting and the antiferromagetic phases is of the first-order, it is accompanied by a phase separation. (literal)
