Investigation of Polarization-Dependent Optical Force in Optical Tweezers using Generalized Lorenz-Mie Theory
Jai-Min Choi, Heeso Noh
In vectorial diffraction theory, tight focusing of a linearly polarized laser beam produces an anisotropic field distribution around the focal plane. We present a numerical investi…
Tuning the Stiffness Asymmetry of Optical Tweezers via Polarization Control
Jinmyoung So, Jai-Min Choi
Optical tweezers that utilize a highly focused, linearly polarized laser beam exhibit strong trap stiffness asymmetry, which originates from the anisotropic field distribution in t…
Direct Observation and Analysis of Spin Dependent Transport of Single Atoms in a 1D Optical Lattice
Michał Karski, Leonid Förster, Jai-Min Choi +4
We have directly observed spin-dependent transport of single cesium atoms in a 1D optical lattice. A superposition of two circularly polarized standing waves is generated from two…
Imprinting Patterns of Neutral Atoms in an Optical Lattice using Magnetic Resonance Techniques
Michał Karski, Leonid Förster, Jai-Min Choi +5
We prepare arbitrary patterns of neutral atoms in a one-dimensional (1D) optical lattice with single-site precision using microwave radiation in a magnetic field gradient. We give…
Microwave Control of Atomic Motion in Optical Lattices
Leonid Förster, Michał Karski, Jai-Min Choi +8
We control the quantum mechanical motion of neutral atoms in an optical lattice by driving microwave transitions between spin states whose trapping potentials are spatially offset.…
Quantum Walk in Position Space with Single Optically Trapped Atoms
Michał Karski, Leonid Förster, Jai-Min Choi +4
The quantum walk is the quantum analogue of the well-known random walk, which forms the basis for models and applications in many realms of science. Its properties are markedly dif…
