Gravitational realization of magnons in a ferromagnetic spin chain
Juan Diego Chang, Rodrigo de Leon Ardon, Juan Ponciano +1
A gravitational model of magnons in thermal equilibrium with a ferromagnetic spin chain is developed in a phenomenological bottom-up approach. A large Schwarzschild-AdS black hole…
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…
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…
