Viscoelastic dynamics of nanoparticles optically trapped in moving fringe pattern in air-filled hollow-core fiber
Soumya Chakraborty, Gordon K. L. Wong, Philip St. J. Russell +1
We report optical trapping and transport of nanoparticles in a moving interference pattern in hollow-core photonic crystal fiber at atmospheric pressure, when competition between t…

Optomagnetic forces on YIG/YFeO3 microspheres levitated in chiral hollow-core photonic crystal fibre
Soumya Chakraborty, Gordon K. L. Wong, Ferdi Oda +9
We explore a magnetooptomechanical system consisting of a single magnetic microparticle optically levitated within the core of a helically twisted single-ring hollow-core photonic…

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…
