Phase transition from a $d_{x^2-y^2}$ to $d_{x^2-y^2}+d_{xy}$ superconductor

We study the phase transition from a $d_{x^{2} - y^{2}}$ to $d_{x^{2} - y^{2}} + d_{x y}$ superconductor using the tight-binding model of two-dimensional cuprates. As the temperature is lowered past the critical temperature $T_{c}$ , first a $d_{x^{2} - y^{2}}$ superconducting phase is created. With further reduction of temperature, the $d_{x^{2} - y^{2}} + d_{x y}$ phase is created at temperature $T = T_{c 1}$ . We study the temperature dependencies of the order parameter, specific heat and spin susceptibility in these mixed-angular-momentum states on square lattice and on a lattice with orthorhombic distortion. The above-mentioned phase transitions are identified by two jumps in specific heat at $T_{c}$ and $T_{c 1}$ .
