Erratum: Collapse and revival oscillations as a probe for the tunneling amplitude in an ultracold Bose gas [Phys. Rev. A 82, 043601 (2010)]

Abstract

In the analytic expression for the revival time in Eq.(13), there is an incorrect factor 2 in the definition of f (u). The correct expression is trev=
∫ u2 u1 duf (u),(1) where f (u)={d2J2 (1− u2)[1−(2γ− u) 2]−(H0− Au) 2}− 1 2(2) and where γ= 2n− 1 and H0=− 4n (1− n) dJ− γA is the energy at the quench (t= 0) up to a constant C≡−(µ− A) γ− A. The boundaries u1 and u2 are determined as the roots of the polynomial of fourth order f− 1 (u)= 0, where u1= γ as described in the article. For the plots in Figs. 6 and 7, the correct integral was used. For the case of half filling, the constant A is missing in the expression for the upper boundary u2 of the preceding integral. The correct expression is u2= A
