From conformal to volume-law for the entanglement entropy in exponentially deformed critical spin 1/2 chains
Giovanni Ramírez, Javier Rodríguez-Laguna, Germán Sierra
An exponential deformation of 1D critical Hamiltonians gives rise to ground states whose entanglement entropy satisfies a volume-law. This effect is exemplified in the XX and Heise…

Entanglement in low-energy states of the random-hopping model
Giovanni Ramírez, Javier Rodríguez-Laguna, Germán Sierra
We study the low-energy states of the 1D random-hopping model in the strong disordered regime. The entanglement structure is shown to depend solely on the probability distribution…
