  We present heuristic arguments that hint to a possible connection of Lorentz
violation with observed phenomenon in condensed matter physics. Various
references from condensed matter literature are cited where operators in the
Standard Model Extension appear to be enhanced. Furthermore, we consider the
Levy-Leblond equation, which is the analogue of Dirac equation in
non-relativistic quantum mechanics. We show that we can obtain the Levy-Leblond
equation by adding enhanced Lorentz violating operators to the Dirac equation.
Based on these observations, we propose that Lorentz violation exhibits itself
in non-relativistic quantum mechanics.
