The work on Coulomb drag acquainted me with the long-standing problem of evaluating the structure factor for interacting one-dimensional quantum particles with a real, non-linear dispersion relation. The existence of this problem was appreciated for quite a while, but little progress was made, as the standard approach based on Tomonaga-Luttinger model proved to be frustratingly ineffective. We managed to solve the problem! Here our breakthrough paper addressing the problem for fermions: cond-mat/0603458. The emerged theoretical description of one-dimensional quantum fluids was dubbed nonlinear Luttinger liquid theory.
