  Fast scramblers are quantum systems which thermalize in a time scale
logarithmic in the number of degrees of freedom of the system. Non-locality has
been argued to be an essential feature of fast scramblers. We provide evidence
in support of the crucial role of non-locality in such systems by considering
the approach to thermalization in a (strongly-coupled) high temperature
non-commutative gauge theory. We show that non-locality inherent to
non-commutative gauge theories does indeed accelerate the rate of dissipation
in the heat bath in stark contrast to the slow random walk diffusive behavior
prevalent in local field theories.
