英文摘要We study the constraint on the inflationary energy scale from the recently proposed trans-Planckian censorship conjecture (TCC). We find a universal upper bound on the inflationary Hubble expansion rate H-inf which is solely determined by the reheating temperature T-rh: H-inf/M-pl less than or similar to T-0/T-rh, where T-0 is the photon temperature today. The upper limit can be saturated by a postinflationary oscillatory stage with the critical equation-of-state parameter w approximate to 1/3, or by an inflation model with multiple stages. In the lowest reheating temperature required for big bang nucleosynthesis, the upper bound on the tensor-to-scalar ratio r at the CMB scales is r less than or similar to 10(-8), which can be realized in many string-inspired inflation models.
