 abstract = {We study defect production in a quantum system subjected to a nonlinear
power-law quench which takes it either through a quantum critical or
multicritical point or along a quantum critical line. We elaborate on
our earlier work [D. Sen, K. Sengupta, and S. Mondal, Phys. Rev. Lett.
101, 016806 (2008)] and present a detailed analysis of the scaling of
the defect density n with the quench rate tau and exponent alpha for
each of the above-mentioned cases. We also compute the correlation
functions for defects generated in nonlinear quenches through a quantum
critical point and discuss the dependence of the amplitudes of such
correlation functions on the exponent alpha. We discuss several
experimental systems where these theoretical predictions can be tested.},
