Klein paradox for bosons, wave packets and negative tunnelling times
(Nature, 2020-11-05)
We analyse a little known aspect of the Klein paradox. A Klein-Gordon boson appears to be able to cross a supercritical rectangular barrier without being reflected, while spending there a negative amount of time. The ...
Nanofocusing of acoustic graphene plasmon polaritons for enhancing mid-infrared molecular fingerprints
(De Gruyter, 2020)
Mid-infrared (mid-IR) optical spectroscopy of molecules is of large interest in physics, chemistry, and biology. However, probing nanometric volumes of molecules is challenging because of the strong mismatch of their ...
Toward Supramolecular Nanozymes for the Photocatalytic Activation of Pt(IV) Anticancer Prodrugs
(Royal Society Of Chemistry, 2020-09-16)
A supramolecular nanozyme for the photocatalytic conversion of a Pt(IV) anticancer complex to cisplatin is described herein. We employed 1.9 nm Au nanoparticles decorated with thiol ligands bearing a TACN (1,4,7-triazacyclononane) ...

First search for the ηc2(1D) in B decays at Belle
(Springer, 2020-05-08)
The first dedicated search for the ηc2(1D) is carried out using the decays B+→ ηc2(1D)K+, B0 → ηc2(1D)K0S, B0→ ηc2(1D)π−K+, and B+→ ηc2(1D)π+K0S with ηc2(1D) → hcγ. No significant signal is found. For the ηc2(1D) mass range ...
The Spanish Plurinational Labyrinth. Practical Reasons for Criticising the Nationalist Bias of Others While Ignoring One’s Own Nationalist Position
(MDPI, 2019-12-31)
To analyse the Spanish national question requires considering the relationship between the idea of the nation and the phenomenon of nationalism on one side, and the question of political plurality on the other. The approval ...
The Musical Bridge—Intercultural Regionalism and the Immigration Challenge in Contemporary Andalusia
(MDPI, 2019-12-30)
The ideals of tolerance and cultural exchange associated with the interfaith past of Muslim Spain (al-Andalus) have become a symbol for Andalusian regionalism and for the integration of Moroccan communities. Nowhere is ...
A Dual-Species Bose-Einstein Condensate with Attractive Interspecies Interactions
(MDPI, 2020-03-21)
We report on the production of a 41 K- 87 Rb dual-species Bose–Einstein condensate with tunable interspecies interaction and we study the mixture in the attractive regime; i.e., for negative values of the interspecies ...
Some New Results on Coincidence Points for Multivalued Suzuki-Type Mappings in Fairly Complete Spaces
(MDPI, 2020-03-17)
In this paper, we introduce Suzuki-type generalized and modified proximal contractive mappings. We establish some coincidence and best proximity point results in fairly complete spaces. Also, we provide coincidence and ...
Identification, Computational Examination, Critical Assessment and Future Considerations of Distance Variables to Assess Collective Tactical Behaviour in Team Invasion Sports by Positional Data: A Systematic Review
(MDPI, 2020-03-17)
The aim of the study was the identification, computational examination, critical assessment and future considerations of distance variables to assess collective tactical behaviour in team invasion sports by positional data. ...
