A truly one-dimensional case is assumed, so that the loss of the (initially high) coherence between the two quasicondensates is due to dephasing only, but not due to the violation of integrability and subsequent thermalization (which are excluded from the present model). We confirm the subexponential time evolution of the coherence between two quasicondensates $\\propto \\exp [-(t/t_0)^{2/3}]$, experimentally observed by S. Hofferberth {\\em et. al.}, Nature {\\bf 449}, 324 (2007).
