Asymmetric quantum transport in a double-stranded Kronig-Penney model
Taksu Cheon, Sergey S. Poghosyan
We introduce a double-stranded Kronig-Penney model and analyze its transport properties. The asymmetric fluxes between two strands with suddenly alternating localization patterns a…

Bloch vector, disclination and exotic quantum holonomy
Atushi Tanaka, Taksu Cheon
A topological formulation of the eigenspace anholonomy, where eigenspaces are interchanged by adiabatic cycles, is introduced. The anholonomy in two-level systems is identified wit…

Exotic quantum holonomy and higher-order exceptional points in quantum kicked tops
Atushi Tanaka, Sang Wook Kim, Taksu Cheon
The correspondence between exotic quantum holonomy that occurs in families of Hermitian cycles, and exceptional points (EPs) for non-Hermitian quantum theory is examined in quantum…
