What happens when a solid starts flowing like a superfluid, yet still creaks like a crystal? This is the remarkable behaviour of a supersolid — a phase of matter that combines crystalline order with frictionless flow. Once a long-standing theoretical curiosity, supersolidity has now been realised in an exceptionally clean and tunable platform: dilute dipolar Bose–Einstein condensates of highly...

We investigate the behaviour of a pair of atomic ensembles confined to optical cavities which couple to one another through the exchange of light. Such atom-cavity systems are widely studied in quantum optics and have parallels to models from other fields, e.g., condensed-matter and nuclear physics. Hence, understanding the behaviour of such systems is relevant both within quantum optics and...

404. Quantum State Tomography of momentum-entangled atom pairs in a dual-resonant matter-wave interferometer

Contributed Oral

Quantum state tomography provides a complete characterisation of quantum systems through measurements performed in multiple complementary bases [1], enabling the reconstruction of the system's density matrix and the quantification of coherence and entanglement. Here, we report the implementation of quantum state tomography for momentum-entangled atom pairs generated in a double-halo source and...

Active baths are the non-equilibrium equivalent of a thermal bath, comprised of several motile active particles that convert the energy in their surroundings into motion. Understanding the statistical and dynamic properties of an active bath of particles, such as E. coli bacteria, have important implications in uncovering novel far-from-equilibrium physics that are potentially generalisable to...
