Unruh effect detection through chirality in curved graphene

Autor: Jairo Martínez-Montoya, J. Madrigal-Melchor, J. R. Suárez-López, Alberto Molgado

We analyze a generalization of the analogue Unruh effect based on curved graphene. To this end, we consider the fourth order in derivatives field theoretic version of the Pais-Uhlenbeck oscillator, for which the Unruh effect may be interpreted as the

Magnetic properties of the ordered and disordered double perovskite Sr2Fe1+xMo1−xO6 (−1 ≤ x ≤ 1/3)

Autor: M. Avignon, J. R. Suárez, F. Estrada, O. Navarro

Publikováno v: The European Physical Journal B. 84:53-58

We have studied the effect of cationic disorder on the spin polarization of the double perovskite system Sr2Fe1+x Mo1−x O6 with −1 ≤ x ≤ 1/3. The composition x = 0 corresponds to the well-known double-perovskite Sr2FeMoO6, which is expected t

Magneto-elastic phase transition in a linear chain within the double and super-exchange model

Autor: Michel Avignon, Oracio Navarro, J R Suárez, E. Vallejo

Publikováno v: Journal of Magnetism and Magnetic Materials. 322:1064-1068

In this work a magneto-elastic phase transition in a linear chain was obtained due the interplay between magnetism and lattice distortion in a double and super-exchange model. We consider a linear chain consisting of classical localized spins interac

Few particles correlation in a one-dimensional quasiperiodic lattice

Autor: O. Navarro, J R Suárez, E. Vallejo, E. Carvajal

Publikováno v: physica status solidi (b). 242:1759-1762

During the last two decades, two of the most important discoveries in condensed matter physics have been the discovery of quasicrystals and the discovery of high-Tc ceramic superconductors. These topics have generated a large number of experimental a
