Holographic entanglement entropy

We study entanglement entropy in the presence of the heat and magnetic fields in the holographic model. Since the heat and magnetic fields are mixed in the holographic model and the heat field is mixed in the holographic model, we find that the entanglement entropy of the holographic model is also proportional to the temperature and the magnetic fields. We also examine the entanglement entropy in the presence of the heat and the magnetic fields in the holographic model. The entanglement entropy decreases towards the heat-field, but increases towards the magnetic fields.
