Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal matter counterparts, yet they exhibit an opposite charge and distinct quantum properties.

AI-driven dialogue analysis confirms popular movies have grown more violent over the past 70 years
Movies often reflect the predominant societal and cultural values at the time they were shot. These values can be expressed in various elements of a film, including the interactions between characters, their communication styles and their characterizing traits.
Researchers observe a phase transition in a 1D chain of atoms using a quantum simulator
Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these transitions have primarily been studied in three-dimensional (3D) and two-dimensional (2D) systems, yet theories suggest that they could also occur in...
Molecular simulations provide new insights into the dynamics of supercoiled DNA
DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, development, reproduction and predispositions of individual humans, can undergo different types of mechanical stress inside cells. For instance, it can...
Surface roughness disrupts glass transition in colloidal ellipsoids, offering a new material design parameter
The so-called glass transition is the process by which some liquid-like materials become solid-like, without forming a crystalline structure. In contrast to conventional solid materials, which exhibit an orderly atom arrangement, glass is characterized by a disordered...
Study demonstrates phase-tunable spin-wave-mediated mutual synchronization of spin Hall nano-oscillators
Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that convert direct current into high-frequency microwave signals through spin wave auto-oscillations. This is a type of nonlinear magnetization oscillations that are self-sustained without the need...
Coupled semiconductor lasers generate novel optical patterns, enabling new spectroscopy techniques
The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects. In the field of optics, coupled light sources (e.g., lasers) can influence each other, producing complex light patterns that cannot be emitted...
Sub-GeV dark matter hunt: SENSEI collaboration reports first findings
Detecting dark matter particles and understanding their underlying physics is a long-standing research goal for many researchers worldwide. Dark matter searches have been aimed at detecting different possible signals that could be associated with the presence of these...
NEON experiment shares results from first direct search for light dark matter
Detecting dark matter, the elusive type of matter predicted to account for most of the universe's mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this matter consists of, various large-scale experiments...
Using phononic bandgap materials to suppress decoherence in quantum computers
Quantum computers have the potential of outperforming classical computers on some optimization and computational tasks. Compared to classical systems, however, quantum systems are more prone to errors, as they are more sensitive to noise and prone to so-called...
