New era of magnetization: Research sheds light on future applications in spintronics and valleytronics
Altermagnets, which exhibit momentum-dependent spin splitting without spin–orbit coupling (SOC) or net magnetization, have recently attracted significant international attention.

Physicists uncover a metallic altermagnet with d-wave spin splitting at room temperature
For many years, physics studies focused on two main types of magnetism, namely ferromagnetism and antiferromagnetism. The first type entails the alignment of electron spins in the same direction, while the latter entails ...

Quantum genesis: The emergence of a flat universe and its mirror from nothing
I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely ...

Revealing the hidden symmetries of a superconductor
A possible method for probing the properties of exotic particles that exist on the surfaces of an unusual type of superconductor has been theoretically proposed by two RIKEN physicists.

Optical fiber link to make CERN more on time than ever
A new optical fiber link between CERN and Paris will provide the Laboratory with an accurate frequency reference, enhancing precision and supporting experiments like ALPHA in their search for matter–antimatter differences.

Optical tweezers reveal forward and backward motion is symmetric in molecular shuttling
In molecular shuttles, a ring molecule is threaded onto a linear molecular strand and can move between two portions of the strand, called stations, in response to external stimuli. Chemical stimuli, light or mechanical forces ...

Simulations reveal Anderson transition for light in 3D disordered systems
The Anderson transition is a phase transition that occurs in disordered systems, which entails a shift from a diffusive state (i.e., in which waves or particles are spread out) to a localized state, in which they are trapped ...

Physicists uncover evidence of two arrows of time emerging from the quantum realm
What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could flow forward or backwards due to processes taking place at the quantum level. This is the thought-provoking ...

Illuminating an asymmetric gap in a topological antiferromagnet
Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their surfaces conduct electricity, yet their interiors do not, instead acting as insulators. Physicists ...
