  We consider the properties of the type II Weyl semimetals at low temperatures
basing on the particular tight - binding model. In the presence of electric
field directed along the line connecting the Weyl points of opposite chirality
the occupied states flow along this axis giving rise to the creation of
electron - hole pairs. The electrons belong to a vicinity of one of the two
type II Weyl points while the holes belong to the vicinity of the other. This
process may be considered as the manifestation of the chiral anomaly that
exists without any external magnetic field. It may be observed experimentally
through the measurement of conductivity. Next, we consider the modification of
the theory in the presence of elastic deformations. In the domain of the
considered model, where it describes the type I Weyl semimetals the elastic
deformations lead to the appearance of emergent gravity. In the domain of the
type II Weyl semimetals the form of the Fermi surface is changed due to the
elastic deformations, and its fluctuations represent the special modes of the
zero sound. We find that there is one - to one correspondence between them and
the sound waves of the elasticity theory. Next, we discuss the influence of the
elastic deformations on the conductivity. The particularly interesting case is
when our model describes the intermediate state between the type I and the type
II Weyl semimetal. Then without the elastic deformations there are the Fermi
lines instead of the Fermi points/Fermi surface, while the DC conductivity
vanishes. However, even small elastic deformations may lead to the appearance
of large conductivity.
