Observation of -symmetry ultralong-range Rydberg molecules
Matthew T. Eiles, Aleksandr Zaitsev, Dominik Dorer +5
We observe weakly-bound -symmetry electronic states in the spectroscopy of Rb+Rb() ultralong-range Rydberg molecules. We detect these molecul…
Precision probing of ionic-core transitions in alkaline-earth Rydberg atoms
Mitsuki Odahara, Shinsuke Haze
We report precision spectroscopy of ionic-core transitions in alkaline-earth Rydberg atoms. We demonstrate high-resolution measurements of isotope shifts and hyperfine splitting of…
Steering reaction flux by coupling product channels
Dominik Dorer, Shinsuke Haze, Jing-Lun Li +5
We demonstrate a method for controlling the outcome of an ultracold chemical few-body reaction by redirecting a tunable fraction of reaction flux from one selected product channel…
Controlling few-body reaction pathways using a Feshbach resonance
Shinsuke Haze, Jinglun Li, Dominik Dorer +5
Gaining control over chemical reactions on the quantum level is a central goal of the modern field of cold and ultracold chemistry. Here, we demonstrate a novel method to coherentl…
Hollow-core fiber for single-mode, low loss transmission of broadband UV light
D. Dorer, M. H. Frosz, S. Haze +3
We report on an anti-resonant hollow-core fiber (AR-HCF) designed for stable transmission of laser light in a broad wavelength range of 250 nm to 450 nm. We tested for wavelengths…
Energy-scaling of the product state distribution for three-body recombination of ultracold atoms
Shinsuke Haze, José P. D'Incao, Dominik Dorer +5
Three-body recombination is a chemical reaction where the collision of three atoms leads to the formation of a diatomic molecule. In the ultracold regime it is expected that the pr…
Spin-conservation propensity rule for three-body recombination of ultracold Rb atoms
Shinsuke Haze, José P. D'Incao, Dominik Dorer +4
We explore the physical origin and the general validity of a propensity rule for the conservation of the hyperfine spin state in three-body recombination. This rule was recently di…
Long-range atom-ion Rydberg molecule: A novel molecular binding mechanism
Markus Deiß, Shinsuke Haze, Johannes Hecker Denschlag
We present a novel binding mechanism where a neutral Rydberg atom and an atomic ion form a molecular bound state at large internuclear distance. The binding mechanism is based on S…
Stark spectroscopy of Rydberg atoms in an atom-ion hybrid trap
Shinsuke Haze, Joschka Wolf, Markus Deiß +3
We report on Rydberg spectroscopy of ultracold atoms in an atom-ion hybrid trap for probing the electric fields in a mixture of atoms and ions. We obtain spectra which exhibit exci…
Observation of spin-orbit-dependent electron scattering using long-range Rydberg molecules
Markus Deiß, Shinsuke Haze, Joschka Wolf +6
We present experimental evidence for spin-orbit interaction of an electron as it scatters from a neutral atom. The scattering process takes place within a Rb ultralong-range Ry…
Cooling dynamics of a single trapped ion via elastic collisions with small-mass atoms
Shinsuke Haze, Mizuki Sasakawa, Ryoichi Saito +2
We demonstrated sympathetic cooling of a single ion in a buffer gas of ultracold atoms with small mass. Efficient collisional cooling was realized by suppressing collision-induced…
Charge-exchange collisions between ultracold fermionic lithium atoms and calcium ions
Shinsuke Haze, Ryoichi Saito, Munekazu Fujinaga +1
Charge exchange collisions between ultracold fermionic 6Li atoms and 40Ca+ ions are observed in the mK temperature range. The reaction product of the charge exchange collision is i…
Experimental realization of a quantum phase transition of polaritonic excitations
Kenji Toyoda, Yuta Matsuno, Atsushi Noguchi +2
We report an experimental realization of the Jaynes-Cummings-Hubbard (JCH) model using the internal and radial phonon states of two trapped ions. An adiabatic transfer correspondin…
Observation of elastic collisions between lithium atoms and calcium ions
Shinsuke Haze, Sousuke Hata, Munekazu Fujinaga +1
We observed elastic collisions between laser-cooled fermionic lithium atoms and calcium ions at the energy range from 100 mK to 3 K. Lithium atoms in an optical-dipole trap were tr…
Generation of a decoherence-free entangled state using a radio frequency dressed state
Atsushi Noguchi, Shinsuke Haze, Kenji Toyoda +1
We propose the generation of entangled states with trapped calcium ions using a combination of an rf dressed state and a spin dependent force. Using this method, a decoherence-free…
