Spatial delocalization of cold oscillators in hollow-core fibers
Soumya Chakraborty, Pardeep Kumar, Gordon K. L. Wong +2
Trapped particles in hollow-core fibers enable long-range sensing, though advanced control of their in-fiber motion, such as multimodal cooling and squeezing, remains challenging.…

Modelling spectra of hot alkali vapour in the saturation regime
Daniel R Häupl, Clare R Higgins, Danielle Pizzey +5
Laser spectroscopy of hot atomic vapours has been studied extensively. Theoretical models that predict the absolute value of the electric susceptibility are crucial for optimising…

Prospects of phase-adaptive cooling of levitated magnetic particles in a hollow-core photonic-crystal fibre
P. Kumar, F. G. Jimenez, S. Chakraborty +3
We analyze the feasibility of cooling of classical motion of a micro- to nano-sized magnetic particle, levitated inside a hollow-core photonic crystal fiber. The cooling action is…
