Perfect transmission of Higgs modes via antibound states
Takeru Nakayama, Shunji Tsuchiya
We study tunneling properties of Higgs modes in superfluid Bose gases in optical lattices in the presence of a potential barrier introduced by local modulation of hopping amplitude…

Nodal topology in -wave superconducting monolayer FeSe
Takeru Nakayama, Tatsuya Shishidou, Daniel F. Agterberg
A nodeless -wave state is likely in superconducting monolayer FeSe on SrTiO. The lack of nodes is surprising but has been shown to be a natural consequence of the observed s…
