Quantum Point Contact with Local Two-body Loss
Kensuke Kakimoto, Shun Uchino
Motivated by recent advances in ultracold atomic gas experiments, we investigate a two-terminal mesoscopic system in which two-body loss occurs locally at the center of a one-dimen…

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…
