2D graphene spin valve leverages van der Waals magnet proximity for efficient spintronics
Graphene, particularly in its purest form, has long been considered a promising material for developing spintronic devices. These devices leverage the intrinsic angular momentum (i.e., spin), as opposed to the charge, of electrons to transmit and process data.
Study explores the effectiveness of honesty oath for reducing dishonest behaviors
Over the past decades, psychologists and policymakers have been trying to devise interventions that could dissuade individuals from engaging in dishonest social behaviors, such as tax evasion or fraud. One promising strategy they identified entails asking people to...
New family of optimized magnetic fields could display enhanced fusion plasma confinement
Physicists have been trying to design fusion reactors, technologies that can generate energy via nuclear fusion processes, for decades. The successful realization of fusion reactors relies on the ability to effectively confine charged particles with magnetic fields,...
Physicists identify key mechanism behind chiral charge density wave in TiSe₂
Chirality is a property of some molecules, subatomic particles, living organisms and other physical or biological systems. This property entails a lack of mirror symmetry in these systems' underlying structures.
Researchers demonstrate universal control of a quantum dot-based system with four singlet-triplet qubits
Being able to precisely manipulate interacting spins in quantum systems is of key importance for the development of reliable and highly performing quantum computers. This has proven to be particularly challenging for nanoscale systems with many spins that are based on...
Quasiperiodicity changes the ground-state properties of 1D narrow-band moiré systems, study demonstrates
Moiré materials, such as twisted bilayer graphene, are materials generally formed by stacking two or more layers of 2D materials on top of each other with a small lattice mismatch. This slight mismatch creates a unique pattern known as the moiré pattern, which is...
Theoretical framework could improve data gathering in biological systems
To effectively adapt to change, living organisms rely on their ability to rapidly detect and process sensory information in their surroundings. The sensory information available at a given time continuously changes, which means that it can typically only be observed...
Mesoporous MoS₂ strategy boosts efficiency and stability of perovskite solar cells
The efficiency and performance of photovoltaics (PVs) have improved significantly over the past decades, which has led to an increase in the adoption of solar technologies. To further enhance the performance of solar cells, energy researchers worldwide have been...
Study gathers strong evidence of the doubly magic nature of ¹⁰⁰Sn
Recent experiments at CERN have shed new light on the nuclear properties of atomic nuclei (i.e., the central regions of atoms accounting for most of their mass). A key objective of recent research into atomic nuclei has been to better understand the properties of...
