Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Physicists have long relied on elegant theorems to connect the abstract math of quantum theory with the tangible behavior of ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

Quantum theory – our best understanding of the world at the smallest level – is famously weird and notoriously confusing. It’s a theory that seems to say particles can be in two places at once, or ...

An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, ...

Katie has a PhD in maths, specializing in the intersection of dynamical systems and number theory. She reports on topics from maths and history to society and animals. Katie has a PhD in maths, ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary ...

According to quantum mechanics, the physics theory that describes the zoo of subatomic particles, all matter can be described as both particles and waves. But is it real? When you purchase through ...

There may be an infinite amount of energy locked in the vacuum of space-time. So could we ever harness this energy for anything useful? The idea of vacuum energy comes from quantum field theory, which ...

A new study enhances hydrogen molecule predictions, achieving unprecedented precision in testing fundamental physics and ...
