Quantum field theory (QFT) provides a comprehensive framework for describing the fundamental interactions of matter and radiation. In the context of atom‐field interactions, QFT elucidates how atoms ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

Sorta sparked by this comment someone made to me but it's similar to what other people have told me before: I was listening to a lecture on quantum electrodynamics and it helped me conceptualize the ...

The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of ...

Quantum mechanics would allow the Universe to eventually tunnel to the lowest energy state, or the ‘true’ vacuum, and that process would result in a cataclysmic global event. (CREDIT: Professor Zlatko ...

Magnetic fields play a pivotal role in quantum chromodynamics (QCD), the fundamental theory of strong interactions. Their presence induces significant modifications in the behaviour of quarks and ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

Tiny highly uniform magnetic fields are known to pervade the universe, influencing various cosmological processes. To date, however, the physical mechanisms underpinning the generation of these fields ...

For two decades, a deceptively simple question has split condensed‑matter physicists: do the electrons in gold quietly align their spins, or is the metal as magnetically featureless as textbooks claim ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has been a cornerstone of the standard model, withstanding the scrutiny of ...

Researchers at the University of Innsbruck have shown that quantum sensors can remain highly accurate even in extremely noisy conditions. It's the first experimental realization of a powerful quantum ...
