A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, ...

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 ...

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

But for all its successes, quantum field theory has its own puzzles. Infamously, a straightforward calculation of the quantum corrections to the scattering probability of two particles often ...

A collaborative team of researchers from the Max Planck Institute for Structure and Dynamics of Matter (MPSD), Nanjing ...

Under quantum field theory, particles interact over zero distance in spacetime. Under the general theory of relativity, the theorized force carrier particle for gravity, the graviton, cannot ...

Albert Einstein’s special theory of relativity, which explains what happens when things move very fast – to create what are known as quantum field theories. Three different quantum field ...

I did my Ph.D. in Theoretical Physics, in the area of Quantum Field Theory, which strangely enough, works amazingly well in explaining the real world. The fact that nature seems to obey the rules ...

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. Physicists have performed a ...

Researchers have successfully simulated particle creation in an expanding universe using IBM's advanced quantum computers.
