Description

In low energy, the gravitational force is well-described by the metric field (spin-2 symmetric tensor field). A question here is whether such a field is fundamental or not. In this talk, we discuss several possibilities that tensorial degrees of freedom emerge from matter. As examples, we are going to introduce the TTbar deformed scalar theory and fermion-induced gravity.
