Electro-Optical Ion Trap for Experiments with Atom-Ion Quantum Hybrid Systems
Applied Sciences, 2020 In the development of atomic, molecular, and optical (AMO) physics, atom-ion hybrid systems are characterized by the presence of a new tool in the experimental AMO toolbox: atom-ion interactions.

Molecules, 2021 Continuous rotation of a cholesteric droplet under the heat gradient was observed by Lehmann in 1900. This phenomenon, the so-called Lehmann effect, consists of unidirectional rotation around the heat flux axis.

Orbital Rotation of Trapped Particle in a Transversely Misaligned Dual-Fiber Optical Trap
IEEE Photonics Journal, 2016 We propose and demonstrate a novel optical orbital rotation technique for trapped particle in a transversely misaligned dual-fiber optical trap. The orbital rotation frequency can be controlled by varying the power of two counterpropagating beams.

Positioning Accuracy in Holographic Optical Traps
Micromachines, 2021 Spatial light modulators (SLMs) have been widely used to achieve dynamic control of optical traps. Often, holographic optical tweezers have been presumed to provide nanometer or sub-nanometer positioning accuracy.

Novel Ion Trap Design for Strong Ion-Cavity Coupling
Atoms, 2016 We present a novel ion trap design which facilitates the integration of an optical fiber cavity into the trap structure. The optical fibers are confined inside hollow electrodes in such a way that tight shielding and free movement of the fibers are ...

Forced Atom Interferometers in Optical Harmonic Potentials
AtomsWe present a study of Doppler-sensitive light-pulse atom interferometers operating within optical dipole potentials, where atomic trajectories are manipulated using momentum transfer from light pulses and optical forces from the trap.

Diffusiophoresis driven colloidal manipulation and shortcuts to adiabaticity
New Journal of Physics, 2021 While compressing a colloidal state by optical means alone has been previously achieved through a specific time-dependence of the trap stiffness, realizing quickly the reverse transformation stumbles upon the necessity of a transiently expulsive trap. To
