Breaking the Area Law: The Rainbow State
Giovanni Ramírez, Javier Rodríguez-Laguna, Germán Sierra
An exponential deformation of a 1D critical Hamiltonian, with couplings falling on a length scale , gives rise to ground states whose entanglement entropy follows a volume…

Quantum Entanglement In Inhomogeneous 1D Systems
Giovanni Ramírez
The entanglement entropy of the ground state of a quantum lattice model with local interactions usually satisfies an area law. However, in 1D systems some violations may appear in…
