Topological order versus many-body localization in periodically modulated spin chains
Takahiro Orito, Yoshihito Kuno, Ikuo Ichinose
In this paper, we study periodically modulated spin chain in a linear gradient potential (LP) that is generated by an external magnetic field. In the absence of the LP, the…

Flat-band many-body localization and ergodicity breaking in the Creutz ladder
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
We study disorder-free many-body localization in the flat-band Creutz ladder, which was recently realized in cold-atoms in an optical lattice. In a non-interacting case, the flat-b…

Extended stream functions for dynamics of Bose-Einstein condensations: Snake instability of dark soliton in ultra-cold atoms as an example
Takahiro Orito, Ikuo Ichinose
In this paper, we formulate extended stream functions (ESFs) to describe the dynamics of Bose-Einstein condensations in the two-dimensional space. The ordinary stream function is a…
