The Hanbury Brown Twiss effect for atomic matter waves

TL;DR

This paper explores the atomic matter wave analogs of the Hanbury Brown Twiss experiment, demonstrating how cold atom experiments with bosons and fermions reveal quantum statistical effects similar to those in optics.

Contribution

It introduces the experimental realization of Hanbury Brown Twiss effects with cold atoms, bridging quantum optics concepts with atomic matter waves.

Findings

Observation of bunching and antibunching in cold atom experiments

Demonstration of quantum statistical effects with both bosons and fermions

Connection to Einstein's thermodynamics of Bose gases

Abstract

This paper discusses our recent work on developing the matter wave analogs to the Hanbury Brown Twiss experiment. We discuss experiments using cold atoms, both bosons and fermions, both coherent and incoherent. Simple concepts from classical and quantum optics suffice to understand most of the results, but the ideas can also be traced back to the work of Einstein on the thermodynamics of Bose gases.
