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…
Symmetry protected phases in inhomogeneous spin chains
Nadir Samos Sáenz de Buruaga, Silvia N. Santalla, Javier Rodríguez-Laguna +1
It has been shown recently that inhomogenous spin chains can exhibit exotic phenomena such as the breaking of the area law of the entanglement entropy. An example is given by the r…
Engineering large end-to-end correlations in finite fermionic chains
Hernán Santos, José E. Alvarellos, Javier Rodríguez-Laguna
We explore deformations of finite chains of independent fermions which give rise to large correlations between their extremes. After a detailed study of the Su-Schrieffer-Heeger (S…
Kardar-Parisi-Zhang Universality in First-Passage Percolation: the Role of Geodesic Degeneracy
Pedro Córdoba-Torres, Silvia N. Santalla, Rodolfo Cuerno +1
We have characterized the scaling behavior of the first-passage percolation (FPP) model on two types of discrete networks, the regular square lattice and the disordered Delaunay la…
