Quantum Entanglement is the biggest mystery of science that could upend life as we know it, writes Satyen K. Bordoloi.

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Visualization of a quantum field theory calculation showing virtual particles in the quantum vacuum. (Specifically, for the strong interactions.) Even in empty space, this vacuum energy is non-zero.

The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology. Professor Albion Lawrence ...

Quantum mechanics is perhaps the most unintuitive theory ever devised. And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum ...

The quantum and gravitational theory group of the Brandeis Physics Department conducts research on a range of topics in theoretical physics, including string theory, classical and quantum gravity, ...

Towards an Ontology for Quantum Field Theory, Philosophy of Science, Vol. 66, Supplement. Proceedings of the 1998 Biennial Meetings of the Philosophy of Science Association.

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 ...

There are several rationales for using a quantum field theory. First, it is a natural generalization of classical field theories, which are our most successful (non-quantum) theories of Nature.

"A quantum theory of gravity is needed to understand what kind of phenomena there are in cases where there's a gravitational field and high energies," says Partanen.
