Magnetic-field control of interactions in alkaline-earth Rydberg atoms and applications to {\it XXZ} models
Masaya Kunimi, Takafumi Tomita
The paper analyzes how magnetic fields modify the interactions between alkaline‑earth Rydberg atoms (Sr and Yb), showing that the resulting effective Hamiltonian is an XXZ spin mod…
Square-root Time Atom Reconfiguration Plan for Lattice-shaped Mobile Tweezers
Koki Aoyama, Takafumi Tomita, Fumihiko Ino
This paper proposes a scalable planning algorithm for creating defect-free atom arrays in neutral-atom systems. The algorithm generates a time plan for a…
Optimization-based hologram design for fine optical tweezer arrays and extension of super-resolution criteria
Keisuke Nishimura, Hiroto Sakai, Takafumi Tomita +2
Aligning light spots into arbitrary shapes is a fundamental challenge in holography, leading to various applications across diverse fields in science and engineering. However, as t…
Proposal for realizing Heisenberg-type quantum-spin models in Rydberg-atom quantum simulators
Masaya Kunimi, Takafumi Tomita
We investigate the magnetic-field dependence of the interaction between two Rydberg atoms, and . In this setting, the effective s…
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…
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…
