El voladís de la Casa de la Universitat de la Ciutat de Mallorca : un compendi d'escultura i fusteria al segle XVII
/
Bauçà de Mirabò Gralla, Concepció (Universidad Pontificia de Comillas. Centro de Enseñanza Superior Alberta Giménez)
La darrera restauració del voladís de l'Ajuntament de Palma recuperà en gran part el valor artístic i simbòlic que aquest havia perdut després d'anys de degradació. L'esmentat element segueix jugant avui un paper rellevant en l'escenografia que desplega la façana de l'edifici consistorial en presidir la plaça de Cort, un nucli fonamental de la vida ciutadana de Palma. [...]
The most recent restoration of the cornice of Palma town hall largely recovered the artistic and symbolic importance it had lost after years of degradation. Today, this element continues to play an important role in the decoration that runs along the facade of the town council building that presides over Plaça de Cort, a key focus of public life in Palma.

Magnetic topological insulators constitute a novel class of materials whose topological surface states (TSSs) coexist with long-range ferromagnetic order, eventually breaking time-reversal symmetry. The subsequent bandgap opening is predicted to co-occur with a distortion of the TSS warped shape from hexagonal to trigonal. [...]

We evidence the possibility for coherent electrical manipulation of the spin orientation of topologically protected edge states in a low-symmetry quantum spin Hall insulator. By using a combination of ab initio simulations, symmetry-based modeling, and large-scale calculations of the spin Hall conductivity, it is shown that small electric fields can efficiently vary the spin textures of edge currents in monolayer 1T'-WTe2 by up to a 90-degree spin rotation, without jeopardizing their topological character.

Some metastable polymorphs of bismuth monolayers (bismuthene) can host non-trivial topological phases. However, it remains unclear whether these polymorphs can become stable through interaction with a substrate, whether their topological properties are preserved, and how to design an optimal substrate to make the topological phase more robust.
