چکیده
|
We construct a bulk geometry with q-lattice structure, which is implemented by two gauge fields and a coupling between the lattice and the maxwell field. this gravity dual model can describe a novel insulator which exhibits some key features analogous to mott insulator. in particular, a hard gap in insulating phase as well as vanishing dc conductivity can be simultaneously achieved. in addition, we discuss the non-drude behavior of the optical conductivity in low frequency region in insulating phase, which exhibits some novel characteristics different from ordinary mott insulator.
