Abstract The effects of the spin–orbit couplings (SOC) including the Rashba and the Dresselhaus interactions are considered for the high T c cuprates with superconducting gap (DSC) and the pseudogap ( d ‐density wave, DDW) phase. The sole Rashba or the Dresselhaus interaction is shown to have a stronger effect on the superconducting phase when compared to the mixed SOC. The temperature dependencies of the DSC and DDW parameters along with the specific heat of both the underdoped and the overdoped cuprates were considered.
