 abstract = {We study the generation of defects when a quantum spin system is
quenched through a multicritical point by changing a parameter of the
Hamiltonian as t/tau, where tau is the characteristic timescale of
quenching. We argue that when a quantum system is quenched across a
multicritical point, the density of defects (n) in the final state is
not necessarily given by the Kibble-Zurek scaling form n similar to
1/tau(d nu)/((z nu+1)), where d is the spatial dimension, and. and z are
respectively the correlation length and dynamical exponent associated
with the quantum critical point. We propose a generalized scaling form
of the defect density given by n similar to 1/(tau d/(2z2)), where the
exponent z(2) determines the behavior of the off-diagonal term of the 2
x 2 Landau-Zener matrix at the multicritical point. This scaling is
valid not only at a multicritical point but also at an ordinary critical
point.},
