Promising strategy leverages atomic displacements to control quantum properties of a vanadate perovskite
Perovskites, materials with a crystal structure that mirrors that of the mineral calcium titanate CaTiO₃, exhibit properties that are advantageous for developing various technologies. For instance, they have proved promising for designing photovoltaic (PV) systems and...
Tiny rotating particles create vorticity in viscous fluids, yielding fascinating new behaviors
Vorticity, a measure of the local rotation or swirling motion in a fluid, has long been studied by physicists and mathematicians. The dynamics of vorticity is governed by the famed Navier-Stokes equations, which tell us that vorticity is produced by the passage of...
New blue light-emitting lasers leverage low-toxicity colloidal quantum dots
Blue lasers, lasers that emit a light beam with a wavelength between 400 nm and 500 nm, are key components of various technologies, ranging from high-resolution displays to printers, medical imaging tools and data storage solutions. A key advantage of these lasers is...
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.
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...
