Consideraciones sobre la cláusula irph a la luz de sus antecedentes y de la doctrina consolidada del tribunal de justicia de la union europea
2021
By issuing its judgment of March 3, 2020, the Court of Justice of the European Union (CJEU) has terminated the last episode in the evolution of the IRPH index to which almost a tenth of mortgages have been referring. in Spain, compared to the rest that the Euribor takes as a reference, declaring in essence that consumers will be able to go to court to declare the abusiveness of the clause that the aforementioned index contains in the deeds of constitution of the mortgage. To understand the scope of the current situation, it is convenient to consider even briefly what the IRPH consists of and the consequences that its application has entailed for the affected consumer borrowers, taking into …
Hierarchies of geometric entanglement
2007
We introduce a class of generalized geometric measures of entanglement. For pure quantum states of $N$ elementary subsystems, they are defined as the distances from the sets of $K$-separable states ($K=2,...,N$). The entire set of generalized geometric measures provides a quantification and hierarchical ordering of the different bipartite and multipartite components of the global geometric entanglement, and allows to discriminate among the different contributions. The extended measures are applied to the study of entanglement in different classes of $N$-qubit pure states. These classes include $W$ and $GHZ$ states, and their symmetric superpositions; symmetric multi-magnon states; cluster s…
Can entanglement be extracted from many body systems?
2007
Some thermodynamical properties of solids, such as heat capacity and magnetic susceptibility, have recently been shown to be linked to the amount of entanglement in a solid. Until now, however, it was not clear whether this entanglement can be used as a resource in quantum information theory. Here we show that this entanglement is physical, demonstrating the principles of its extraction from a typical spin chain by scattering two particles off the system. Moreover, we show how to simulate this process using present-day optical lattice technology. © 2007 World Scientific Publishing Company.
