Description
The zero magneto resistance (ZMR) observed in polyacetylene
nanofibers in high electric field is explained with the de-confined
conduction of spinless charged solitons akin to a Majorana fermion state
as 1-D topological insulator. Similar ZMR is also observed in MoS2 which
is understood as due to the sliding charge density wave (CDW) in high
electric field. The results are the evidences of zero magnetic moment of
the sliding collective excitations in low dimensional systems.
