Ever since its first proposal in 1976,Jackiw-Rebbi zero-mode has been drawing extensive attention for its charming properties including charge fractionalization,topologically protected zero-energy and possible non-Abelian statistics.We investigate these properties through theJackiw-gebbi zero-modes in quantum spin Hall insulators.Though charge fractionalization is not manifested,Jackiw-Rebbi zero-mode’s zero-energy nature leads to a double-frequency Aharonov-Bohm effect,implying that it can be viewed as a special case of Majorana zero-mode without particle-hole symmetry.Such relation is strengthened for Jackiw-Rebbi zero-modes also exhibiting non-Abelian properties in the absence of superconductivity.Furthermore,in the condition that the degeneracy of Jackiw-Rebbi zero-modes is lifted,we demonstrate a novel non-Abelian braiding with continuously tunable fusion rule,which is a generalization of Majorana zero-modes’ braiding properties.
