Holographic complexity for Lifshitz system

The subregion holographic complexity of a $3 + 1$-dimensional Lifshitz spacetime having a scaling symmetry is computed. The change in the holographic complexity between the excited state and the ground state is then obtained. It is found that there is a nontrivial change in holographic complexity at first order in the perturbation of the pure Lifshitz geometry. The difference is next related to the changes in the energy and the entanglement chemical potential of the system. The calculation is carried out for both the values of the dynamical scaling exponent $z$ in the Lifshitz spacetime. The relations have a very similar form to the corresponding relation involving the change in entanglement entropy known to be an analogous relation to the first law of thermodynamics.
