We consider a vacuum to be the lowest energy state of the Universe. But it's possible that there's an even lower-energy, more ...

A new method developed at LMU overcomes fundamental resolution limits and may provide insights into high-temperature ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...

A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon ...

Lattice gauge theory provides a powerful framework for discretising gauge theories to explore the fundamental interactions that underlie particle physics and complex condensed matter phenomena. By ...

The background: To understand how complex materials behave at the atomic level, physicists calculate what are known as ...

For the first time, scientists have directly imaged the quantum process underlying superconductivity, a phenomenon in which ...

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

By adapting ideas from gauge theory, the researchers show how quantum information spread-out across a machine can be measured using only local checks, significantly lowering computing overhead. Their ...
