Many incompletely understood phenomena lurk in the borderlands between physical theories - between classical and quantum, between rays and waves, and so on. These borderlands - the domain of physical ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

Theoretical physicists have established a close connection between the two rapidly developing fields in theoretical physics, quantum information theory and non-invertible symmetries in particle ...

This correspondence suggests that certain properties of black holes can be understood through the lens of CFT, which is a type of quantum field theory that is invariant under conformal ...

Rubies and emeralds have the colors they do because, like many substances, they absorb some colors of light. Most visible light, like sunlight, is composed of all the colors of the rainbow: red, ...

Complex Langevin Dynamics is an innovative approach in quantum field theory (QFT) that addresses significant computational challenges, particularly the notorious "sign problem." This problem ...

Physicists have performed a groundbreaking simulation they say sheds new light on an elusive phenomenon that could determine the ultimate fate of the Universe.
