    A useful way to obtain the central charge of entanglement Hamiltonian -- Nested entanglement entropy

    In this paper, we review how to obtain the central charge of a critical entanglement Hamiltonian through the nested entanglement entropy which was first introduced in [J. Lou et al. PRB 84, 245128 (2011)]. The critical phenomena of the entanglement Hamiltonian can be identified by the central charge obtained by the nested entanglement entropy. We review our previous studies[J. Lou et al. PRB 84, 245128 (2011), S. Tanaka et al. PRA 87, 214401 (2013)] in which we investigated certain entanglement nature of two-dimensional valence-bond-solid (VBS) state and quantum hard-square models on square and triangle ladders using the nested entanglement entropy.Comment: 5 pages, 3 figures, to appear in Interdisciplinary Information Science

    Existiendo un claro desfase entre el actual Catálogo de Áreas de Conocimiento de la Ley Universitaria ,con sus Descriptores, y la realidad de la investigación en Arquitectura y Urbanismo, por cuanto no es encuadrable en la división, apartados y catalogación que aquella propone, es urgente su revisión, máxime con la nueva Reforma que la LOU va a sufrir y las líneas que ésta va a implantar

    Statistical switching kinetics in ferroelectrics

    Full text link
    By assuming a more realistic nucleation and polarization reversal scenario we build a new statistical switching model for ferroelectrics, which is different from either the Kolmogorov-Avrami-Ishibashi (KAI) model or the Nucleation-Limited-Switching (NLS) model. After incorporating a time-dependent depolarization field this model gives a good description about the retardation behavior in polycrystalline thin films at medium or low fields, which can not be described by the traditional KAI model. This model predicts correctly n=1 for polycrystalline thin films at high Eappl or ceramic bulks in the ideal case
