Superfluid helium reveals a manageable analog to the Schwinger effect. It deepens understanding of vortices and quantum ...

The theory failed to unite gravity and quantum mechanics. But it still has become one of the most useful tools in science.

Field Theory in Webster Groves offers new options for outdoor enthusiasts From the co-owner of Civil Alchemy, the shop in the Old Orchard neighborhood specializes in outdoor apparel, gear, and ...

Ivan Todorov, theoretical physicist of outstanding academic achievements and a man of remarkable moral integrity, passed away ...

Might the universe we can observe be just half the tale, with a mirror universe moving in reverse through time filling out ...

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 ...

Quantum mechanics isn’t sufficient to explain the Universe; for that, quantum field theory is needed. This is why. Schematic animation of a continuous beam of light being dispersed by a prism.

So in your head every time you read or hear “conformal field theory” you can just replace it with “scale invariant field theory”. Our universe is, by and large, decidedly not scale invariant.

The quantum field theory framework needed some adjustment for Borinsky and Vogtmann to get the right count. For instance, in quantum field theory, two graphs that are mirror images of each other are ...
