| 摘 要： | We investigate in underdoped cuprates possible coexistence of the superconducting order at zero momentum and pair density wave(PDW) at momentum Q=(π,π) in the presence of a Neel order.By symmetry,the d-wave uniform singlet pairing dS0 can coexist with the d-wave triplet PDW dTQ,and the p-wave singlet PDW pSQ can coexist with the p-wave uniform triplet pT0.At half filling,we find that the novel pSQ+pT0 state is energeticall.y more ...
