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 […]

spallation Progress in particle physics has traditionally been achieved by a symbiosis of experiments at the energy and intensity frontiers and model-building. This has led to the current situation of the Standard Model (SM) representing our best knowledge of particle physics, but which leaves a number of open questions to be resolved. These include the […]

An international research team has presented a new quantum platform based on the electron spin of single atoms on a solid surface, achieving a ‘multiple qubit (quantum bit)’ system using three electron spins. Unlike previous atomic quantum devices on surfaces where only a single qubit could be controlled, the researchers have successfully demonstrated the ability […]

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 […]

Global energy demand is expected to rise around 30% by 2040 according to the International Energy Agency (IEA). Hydrogen (H2) produced by the electrolysis of water, using renewable electricity, the so-called green hydrogen, has emerged as a promising energy vector to respond to this increasing energy demand with the potential to decarbonize transportation, heating, and […]

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 […]

Phase transitions and their related phenomena lie at the core of modern statistical mechanics and condensed matter physics. At equilibrium, an intriguing aspect of second-order phase transitions is that systems with distinct order parameters can be described by the same set of static critical exponents, a hallmark of universality. Thomas Kibble’s research on phase transitions […]

As early as the 1970s, it was suggested that one-particle reduced density matrix functional theory could be an attractive alternative formalism to wave function-based methods. Unfortunately, calculations based on exact functionals generated by the constrained-search formulation are computationally too expensive, which has prompted the development of approximate functionals for practical applications. The functionals currently in […]
