A new dissipation-based method to probe quantum correlations
Quantum systems are known to be prone to dissipation, a process that entails the irreversible loss of energy and that is typically linked to decoherence. Decoherence, or the loss of coherence, occurs when interactions between ...
How do bird nests stay together? Researchers unravel entanglement between stiff, straight rods
The concept of constructing a self-supporting structure made of rods—without the use of nails, ropes, or glue—dates back to Leonardo da Vinci. In the Codex Atlanticus, da Vinci illustrated a design for a self-supporting ...

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 cosmology with final states can explain the accelerated expansion of the universe
Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and that it is not compatible ...
High-intensity shock tube reveals high-speed interface flow mechanism
Research teams have established a theoretical method for designing smooth curved wall surfaces with variable cross-section shock tubes, and developed an integrated, high-intensity multifunctional shock tube device. Led by ...
