Algebra of Majorana Doubling    [PDF]

Jaehoon Lee, Frank Wilczek

Motivated by the problem of identifying Majorana mode operators at junctions, we analyze a basic algebraic structure leading to a doubled spectrum. In general the emergent mode creation operator is highly non-linear in the original effective mode operators, and therefore also in the underlying electron creation and destruction operators. We briefly compare and contrast related issues in the Pfaffian quantum Hall state.
