Electro-Optical Metalens for Near-Surface Cooling of a Levitated Particle
Pedro Rosso Gomez, Bruno Melo, Adeel Afridi +3
Advanced levitation optomechanics in the quantum regime requires sophisticated quantumengineered protocols operating at shorter length and time scales, demanding an increasing cont…
3D trapping of a meta-atom in an intensity minimum
Bin Lu, Adeel Afridi, Nadine Meyer +1
High-refractive-index particles have recently attracted a growing interest in optical levitation experiments, offering the ability to further engineer optical forces through electr…
Cooling of an optically levitated nanoparticle via measurement-free coherent feedback
Bruno Melo, Daniel Veldhuizen, Gregoire F. M. Tomassi +2
We demonstrate coherent, measurement-free optical feedback control of a levitated nanoparticle, achieving phonon occupations down to a few hundred phonons. Unlike measurement-based…
Controlling the sign of optical forces using metaoptics
Adeel Afridi, Bruno Melo, Nadine Meyer +1
Precise manipulation of small objects using light holds transformative potential across diverse fields. While research in optical trapping and manipulation predominantly relies on…
Accelerated State Expansion of a Nanoparticle in a Dark Inverted Potential
Gregoire F. M. Tomassi, Daniel Veldhuizen, Bruno Melo +5
While the wave packet of a massive particle grows linearly under free dynamics, it grows exponentially in an inverted harmonic potential, offering a pathway to rapidly increase qua…
Optical Supertorque Induced by Mie-Resonant Modes
Ivan Toftul, Mihail Petrov, Romain Quidant +1
We introduce the concept of resonant optical torque that allows enhancing substantially a transfer of optical angular momentum (AM) of light to a subwavelength particle. We conside…
Vacuum levitation and motion control on chip
Bruno Melo, Marc T. Cuairan, Gregoire F. M. Tomassi +2
Levitation in vacuum has evolved into a versatile technique which has already benefited diverse scientific directions, from force sensing and thermodynamics to material science and…
Accurate mass measurement of a levitated nanomechanical resonator for precision force sensing
Francesco Ricci, Marc T. Cuairan, Gerard P. Conangla +2
Nanomechanical resonators are widely operated as force and mass sensors with sensitivities in the zepto-Newton and yocto-gram regime, respectively. Their accuracy, however, is usua…
