A step towards quantum gravity

In Einstein's theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein's equations by using quantities that ...

Ultracold atoms dressed by light simulate gauge theories

Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons or quarks) and explain ...

Robotic motion in curved space defies standard laws of physics

When humans, animals, and machines move throughout the world, they always push against something, whether it's the ground, air, or water. Until recently, physicists believed this to be a constant, following the law of conservation ...

Do 'bouncing universes' have a beginning?

In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.

Up a creek without paddle? Researchers suggest 'gunwale bobbing'

Stand up in a canoe and you'll probably find yourself in the water before too long. Jump up and down on the upper edges of the sides of the canoe, and you'll likely end up in the drink as well. But get the balance right and ...

Putting a new spin on the football spiral

Only a handful of researchers have studied why an American football flies in such a unique trajectory, rifling through the air with remarkable precision, but also swerving, wobbling, and even tumbling as it barrels downfield. ...

In search of universal laws of diffusion with resetting

The manner in which animals penetrate a neighborhood searching for food shows similarities to the movements of liquid particles in plant capillaries or gas molecules near an absorbing wall. These phenomena—and many others ...

Optimizing SWAP networks for quantum computing

A research partnership at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) and Chicago-based Super.tech (acquired by ColdQuanta in May 2022) demonstrated how to optimize the execution ...

New materials research sees transformations at an atomic level

When manufacturing techniques turn metals, ceramics or composites into a technologically useful form, understanding the mechanism of the phase transformation process is essential to shape the behavior of those high-performance ...
