Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to ...

The level of sociability for atoms and subatomic particles depends on how much spin they have, which is a measure of how fast they spin around themselves. Atoms and subatomic particles with integer ...

Particles can be classified as bosons or fermions. A defining characteristic of a boson is its ability to pile into a single quantum state with other bosons. Fermions are not allowed to do this. One ...

When a one-dimensional gas of strongly interacting bosons expands, the velocity distribution of the bosons transforms into one that is identical to non-interacting fermions. Bosons and fermions, the ...

More than 40 years ago, Andreev, Lifshitz and Chester suggested the possible existence of a peculiar solid phase of matter, the microscopic constituents of which can flow superfluidly without ...

The standard model (SM) of particle physics has developed as a result of painstaking work, over several decades, by a large number of physicists. It is a quantum field theory, combining quantum ...

Physicists are on the hunt for dark forces. These forces are not as ominous as they sound: “dark” simply refers to the fact that no one has observed them before. In this case, they would act between ...

This press release is also available in German. There are two fundamentally distinct families of particles in nature: bosons and fermions. Being a boson or a fermion has profound consequences on the ...
