Interaction and filling induced quantum phases of dual Mott insulators of bosons and fermions
Seiji Sugawa, Kensuke Inaba, Shintaro Taie +3
Many-body effects are at the very heart of diverse phenomena found in condensed-matter physics. One striking example is the Mott insulator phase where conductivity is suppressed as…
Realization of SU(2)*SU(6) Fermi System
Shintaro Taie, Yosuke Takasu, Seiji Sugawa +4
We report the realization of a novel degenerate Fermi mixture with an SU(2)*SU(6) symmetry in a cold atomic gas. We successfully cool the mixture of the two fermionic isotopes of y…
Nanometer-scale spatial modulation of an inter-atomic interaction in a Bose-Einstein condensate
Rekishu Yamazaki, Shintaro Taie, Seiji Sugawa +1
We demonstrate nanometer-scale spatial control of inter-atomic interactions in a Bose-Einstein condensate of ytterbium(Yb). A pulsed optical standing wave, tuned near an optical Fe…
Quantum gate using qubit states separated by terahertz
K. Toyoda, S. Haze, R. Yamazaki +1
A two-qubit quantum gate is realized using electronic excited states in a single ion with an energy separation on the order of a terahertz times the Planck constant as a qubit. Two…
