Query: An example of a violation of the quantum inequalities for a massless
  scalar field in 1-1 dimensional space-time   It is well known that the energy density of a quantum state can be negative.
It has been shown that there are limits on this negative energy density which
are called the quantum inequalities. In this paper we will demonstrate an
example of a quantum state which violates the quantum inequalities.
