Phys. Rev. Lett. 92, 067002 (2004) [4 pages]Incipient Order in the t-J Model at High TemperaturesSee Also: Erratum Received 12 June 2003; published 10 February 2004 We analyze the high-temperature behavior of the susceptibilities towards a number of possible ordered states in the t-J-V model using the high-temperature series expansion. From all diagrams with up to ten edges, reliable results are obtained down to temperatures of order J, or (with some optimism) to J/2. In the unphysical regime, t<J, large superconducting susceptibilities are found which, moreover, increase with decreasing temperatures, but for t>J, these susceptibilities are small and decreasing with decreasing temperature; this suggests that the t-J model does not support high-temperature superconductivity. We also find modest evidence of a tendency toward nematic and d-density wave orders. © 2004 The American Physical Society URL:
