A holographic dual description of inhomogeneous systems is discussed. Notably, finite temperature results for the entanglement entropy in both the rainbow chain and the SSD model are obtained holographically by choosing appropriate foliations of the BTZ spacetime. Other inhomogeneous theories are also discussed. The entanglement entropy results are verified numerically, indicating that a wide variety of inhomogeneous field theory phenomenology can be seen in different slicings of asymptotically $AdS_3$ spacetimes.

    hep-th 2026-07 accept novelty 5.0

    Periodically driven non-relativistic conformal field theories show three Floquet phases — oscillatory, heating, and power-law transition — fixed exactly by the SO(2,1) representation parameter ρ.
