First experimental evidence of hopfions in crystals

First experimental evidence of hopfions in crystals

Condensed matterMaterialsPhysics

By César Tomé

Hopfions, magnetic spin structures predicted decades ago, have become a hot and challenging research topic in recent years. The first experimental evidence has just been presented in Nature . A deeper understanding of how different components of materials function is important for the development of innovative materials and future technology. The research field of spintronics […]

Chemical contamination of water bodies on one hand, and water shortages due to overexploitation on the other, have increased the need for effective and efficient water treatment and decontamination processes. Two important aspects need to be taken into consideration to define what is an “effective and efficient” treatment. First, as current methods of removing pathogens […]

nanocolloids The increasing attention to the design and experimental development of self-oscillating matter is primarily motivated by the potential use of such systems in emerging technologies (e.g., light engines) comprising compact components and minimum energy consumption. Self-oscillation is the generation of a periodic change in a system fuelled by a steady, non-periodic power source. The […]

The recent COVID-19 pandemic has demonstrated the vulnerabilities of our society to infectious diseases and the limitations of the tools available for viruses detection. Polymerase chain reaction (PCR) and antigens tests have been useful to monitor and contain the extension of the last pandemic, however it demonstrated to have severe limitations. PCR is a highly […]

roof Concrete sidewalks, black asphalt streets, traffic, brick and steel buildings. These common city elements can retain heat and increase temperatures in a phenomenon called the urban heat island effect. With increasingly warming temperatures during the summer months, urban cities like Chicago need to arm decision makers and communities with information about strategies to help […]

BiomedicineMolecular biology

By Rosa García-Verdugo

One of the biggest challenges of medical imaging technologies is actually resolving the structures of interest, be it a tumour, a lung or a blood vessel, without the “noise” from other bodily parts like skin or muscle. A new imaging technique allows for visualisation inside intact animals at higher resolution than ever before. A team […]

The intricate relationship between lattice geometry and topological electronic behaviour determines the ground state properties of materials. The non-trivial band topology of the kagome lattice – it consists of the vertices and edges of the trihexagonal tiling – is being extensively explored as candidates to engineer Dirac fermions, topological flat bands, magnetic Weyl semimetals or […]

By César Tomé

Billions of tiny particles packed into rechargeable lithium-ion battery electrodes are responsible for storing charge and making it available when it’s needed to do work. X-ray movies of this process show the particles absorbing and releasing lithium ions as the battery charges and discharges. Now, in an important step forward, researchers have used a type […]

Magnons or spin waves are elementary quasiparticles, which represent a collective motion of magnetic moments in ordered systems. Spin waves can propagate in materials and therewith transport a spin current. This spin flow requires no electrical charge transport and therefore no electrical losses creating Joule heating. Spin waves enclose a wide frequency range, from gigahertz […]
