Research reveals a surprising topological reversal in quantum systems

In principle, one shouldn't compare apples to oranges. However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both ...

Cold Coulomb crystals, cosmic clues: Unraveling the mysteries of space chemistry

While it may not look like it, the interstellar space between stars is far from empty. Atoms, ions, molecules, and more reside in this ethereal environment known as the Interstellar Medium (ISM). The ISM has fascinated scientists ...

Beyond equilibrium: Scientists investigate Floquet Fermi liquids

Researchers from Germany and Singapore have studied a non-equilibrium state of Fermi liquids called the Floquet Fermi liquid (FFL), which is formed when Fermi liquids are subjected to a periodic driving force and kept in ...

Quantum electronics: Charge travels like light in bilayer graphene

An international research team led by the University of Göttingen has demonstrated experimentally that electrons in naturally occurring double-layer graphene move like particles without any mass, in the same way that light ...

How logic alone may prove that time doesn't exist

Modern physics suggests time may be an illusion. Einstein's theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously—with no special ...

Study uses thermodynamics to describe expansion of the universe

The idea that the universe is expanding dates from almost a century ago. It was first put forward by Belgian cosmologist Georges Lemaître (1894–1966) in 1927 and confirmed observationally by American astronomer Edwin Hubble ...
