Piercing the rainbow: entanglement on an inhomogeneous spin chain with a defect
Nadir Samos Sáenz de Buruaga, Silvia N. Santalla, Javier Rodríguez-Laguna +1
The {\em rainbow state} denotes a set of valence bond states organized concentrically around the center of a spin 1/2 chain. It is the ground state of an inhomogeneous XX Hamiltoni…
Nanowire reconstruction under external magnetic fields
Eva M. Fernández, Silvia N. Santalla, José Enrique Alvarellos +1
We consider the different structures that a magnetic nanowire adsorbed on a surface may adopt under the influence of external magnetic or electric fields. First, we propose a theor…
Efficient computation of matrix elements of generic Slater determinants
Javier Rodríguez-Laguna, Luis Miguel Robledo, Jorge Dukelsky
We present an extension of the Löwdin strategy to find arbitrary matrix elements of generic Slater determinants. The new method applies to arbitrary number of fermionic operators,…
Entanglement as geometry and flow
Sudipto Singha Roy, Silvia N. Santalla, Javier Rodríguez-Laguna +1
We explore the connection between the area law for entanglement and geometry by representing the entanglement entropies corresponding to all bipartitions of an -party pure…
