Building a doped Mott system by holography

Understand

We construct a holographic model in the framework of Q-lattices whose dual exhibits metal-insulator transitions.

• By introducing an interacting term between the Q-lattice and the electromagnetic field in bulk geometry, we find such kind of transition can be Mott-like.
• The evidences are presented as follows.
• i) The transition from a metallic phase to an insulating phase occurs when the lattice constant becomes larger.
