Generation of Motional Squeezed States for Neutral Atoms in Optical Tweezers
Vincent Lienhard, Romain Martin, Yuki Torii Chew +3
Optical tweezers are a powerful tool for the precise positioning of a variety of small objects, including single neutral atoms. Once trapped, atoms can be cooled to the motional gr…
Measurement and feed-forward correction of the fast phase noise of lasers
Tom Denecker, Yukii Torii Chew, Oscar Guillemant +4
Lasers are the workhorse of quantum engineering in the atomic-molecular-optic community. However, phase noise of the laser, which can be especially large in popular semiconductor-b…
Atom Camera: Super-resolution scanning microscope of a light pattern with a single ultracold atom
Takafumi Tomita, Yuki Torii Chew, Rene Villela +6
Sub-micrometer scale light patterns play a pivotal role in various fields, including biology, biophysics, and AMO physics. High-resolution, in situ observation of light profiles is…
Generation of 480 nm picosecond pulses for ultrafast excitation of Rydberg atoms
Tirumalasetty Panduranga Mahesh, Takuya Matsubara, Yuki Torii Chew +3
Atoms in Rydberg states are an important building block for emerging quantum technologies. While the excitation to the Rydberg orbitals are typically achieved in more than tens of…
Ultra-precise holographic optical tweezers array
Yuki Torii Chew, Martin Poitrinal, Takafumi Tomita +4
Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technica…
Strong Spin-Motion Coupling in the Ultrafast Dynamics of Rydberg Atoms
Vineet Bharti, Seiji Sugawa, Masaya Kunimi +7
Rydberg atoms in optical lattices and tweezers is now a well established platform for simulating quantum spin systems. However, the role of the atoms' spatial wavefunction has not…
Ultrafast energy exchange between two single Rydberg atoms on the nanosecond timescale
Yeelai Chew, Takafumi Tomita, Tirumalasetty Panduranga Mahesh +3
Rydberg atoms, with their giant electronic orbitals, exhibit dipole-dipole interaction reaching the GHz range at a distance of a micron, making them a prominent contender for reali…
Ultrafast creation of overlapping Rydberg electrons in an atomic BEC and Mott-insulator lattice
Michiteru Mizoguchi, Yichi Zhang, Masaya Kunimi +13
An array of ultracold atoms in an optical lattice (Mott insulator) excited to a state where single electron wave-functions spatially overlap would represent a new and ideal platfor…
