This paper consists of two important theoretical observations on theinterplay between l = 2 condensates; d-density wave (ddw), electronic nematicand d-wave superconducting states. (1) There is SO(4) invariance at atransition between the nematic and d-wave superconducting states. The nematicand d-wave pairing operators can be rotated into each other by pseudospin SU(2)generators, which are s-wave pairing and electron density operators. Thedifference between the current work and the previous O(4) symmetry at atransition between the ddw and d-wave superconducting states (Nayak 2000 Phys.Rev. B 62 R6135) is presented. (2) The nematic and ddw operators transform intoeach other under a unitary transformation. Thus, when a Hamiltonian isinvariant under such a transformation, the two states are exactly degenerate.The competition between the nematic and ddw states in the presence of adegeneracy breaking term is discussed.

Intimate relations between electronic nematic, d-density wave and d-wave superconducting states
