Bogoliubov analysis of Higgs mode in trapped Fermi superfluids with spatial inhomogeneity
Kensuke Kakimoto, Junichi Takahashi, Yoshiya Yamanaka
The Higgs mode is a key component in the spontaneous breaking of a continuous symmetry along with the Nambu-Goldstone mode, and has been studied extensively for homogeneous systems…

Bose-Einstein condensation of five clusters in Ne and supersolidity
S. Ohkubo, J. Takahashi, Y. Yamanaka
We show that the five cluster states recently observed in Ne, slightly above the five threshold energy, are Bose-Einstein condensates of five clusters. The st…

Quantum Reservoir Computing Using Bose-Einstein Condensate with Damping
Yuki Kurokawa, Junichi Takahashi, Yoshiya Yamanaka
Quantum reservoir computing is a type of machine learning in which the high-dimensional Hilbert space of quantum systems contributes to performance. In this study, we employ the Bo…
