High-precision calculations in quantum statistical physics using a divergent sum

Theorists from LKB and LPS have developped a new method for computing properties of many fermions.

Theorists from LKB and LPS have developped a new method for computing properties of many fermions that interact strongly. The first results agree with experimental measurements on ultracold atomic gases.

The development of such a method is important for several branches of physics, such as nuclear physics or solid-state physics.

Example of Feynman diagram taken into account in the calculation. Arrows represent fermions, and rectangle represent pairs of fermions.
