Creativity and Innovation in Cante from the Estado Novo to the present

UID/HIS/04666/2019 Copyright Year 2020As we covered through Cante Alentejano throughout the 20th century to the present day, we intend to identify its practices and roles in different historical periods, verifying its adaptability and capacity to recreate and innovate over time.  We also intend to verify, in its relationship with the power, how Cante was able to review itself in these historical moments and how this contributed to its dissemination and also to be recognized as Intangible Heritage by UNESCO and what were the consequences of this recognition. In its ability to address new realities, we also want to measure how Cante combines in experimental projects with other musical expressions and how important the teaching of Cante is in the classroom for its protection.authorsversionpublishe

The poets of territorial space in the Garbe al-Andalus of the first Renaissance (11th to 13th centuries)

UIDB/04666/2020 UIDP/04666/2020The territorial space of our focus locates in the Iberian Peninsula. It is delimited to the West and takes the designation of Garbe al-Andalus in the historical period under study: the end of the 10th to the 13th century. We will find almost five dozen essential poets in this brief historical period of about 250 years. We propose to demonstrate how they will mark the poetic perpetuity in the context of the civilizational apogee of this region, enabling the emergence of what is considered the first Renaissance in al-Andalus. In this western region of the peninsula where the new kingdom of Portugal will emerge, we still intend to understand the influence of the poetry referred to over the centuries and its relevance as its interpretation continues in contemporary times.publishersversionpublishe

Current-driven skyrmion motion along disordered magnetic tracks

The motion of skyrmions along ferromagnetic strips driven by current pulses is theoretically analyzed by means of micromagnetic simulations. Analytical expressions describing the skyrmion dynamics during and after the current pulse are obtained from an extended rigid skyrmion model, and its predictions are compared with full micromagnetic simulations for perfect samples with a remarkable agreement. The dynamics along realistic samples with random disorder is also studied by both models. Our analysis describes the relevant ingredients behind the current-driven skyrmion dynamics, and it is expected to be useful to understand recent and future experimental.Comment: Micromagnetic simulations and analytical expressions describing the dynamics of skyrmions under current-pulses along realistic strip

Current-driven domain wall motion along ferromagnetic strips with periodically-modulated perpendicular anisotropy

The dynamics of magnetic domain walls along ferromagnetic strips with spatially modulated perpendicular magnetic anisotropy is theoretically studied by means of micromagnetic simulations. Ferromagnetic layers with a periodic sawtooth profile of the anisotropy depict a well-defined set of energy minima where the walls are pinned in the absence of external stimuli, and favor the unidirectional propagation of domain walls. The performance of the current-driven domain wall motion along these ratchet-like systems is compared to the field-driven case. Our study indicates that the current-driven domain wall motion exhibits significant improvements with respect to the field-driven case in terms of bit shifting speed and storage density, and therefore, it is suggested for the development of novel devices. The feasibility of these current-driven ratchet devices is studied by means of realistic micromagnetic simulations and supported by a one-dimensional model updated to take into account the periodic sawthooth anisotropy profile. Finally, the current-driven domain wall motion is also evaluated in systems with a triangular modulation of the anisotropy designed to promote the bidirectional shifting of series of walls, a functionality that cannot be achieved by magnetic fields.Comment: 32 pages, 11 figure
