Electrons on edge
(Department of Physics, University of Maryland)
Abstract: First, a simple theory of an electron state
localized at the end of a one-dimensional system inside an energy gap is
presented. Then, the results are applied to describe the following
Various experiments are proposed to detect the edge electron states.
Chiral edge states in the quantum Hall regime of the quasi-one-dimensional
organic conductors (TMTSF)2X
Midgap Andreev bound states in the triplet superconducting state of
Chiral edge states and spin quantum Hall effect in the triplet superconductor
are briefly discussed.
Solitons in polyacetylene
Midgap Andreev bound states in d-wave cuprate superconductors
Edge states in graphite and carbon nanotubes
