Title: 
Optical Nanofibres and Cold Rubidium Atoms 

Abstract:
The use of optical nanofibres, that is silica optical fibres with a subwavelength diameter, in quantum systems is already well-documented with a large number of theoretical and experimental studies reported during the last two decades.   Optical nanofibres can provide very high intensity electric fields with a very steep field gradient at their surface.  Such an electric field can be used to study spin-selection rules in single-frequency, two-photon excitation via non-paraxial light or electric quadrupole excitations in atomic systems.   Here, I will discuss our recent work on integration of Rydberg atoms with optical nanofibres with the aim of designing a 1D chain of Rydberg with interactions mediated via the nanofibre.  I will also show how machine learning can optimize the trap occupancy in fibre-based dipole traps and present some nanofibre based cavity designs suitable for cavity QED.
