Interfaces between topologically distinct phases of matter reveal a remarkably rich phenomenology. We study the experimentally relevant interface between a Laughlin phase at filling factor ν = 1/3 and a Halperin 332 phase at filling factor ν = 2/5. Based on our recent construction of chiral topological interfaces (Nat. Commun. https://doi.org/10.1038/s41467-019-09168-z; 2019), we study a family of model wavefunctions that captures both the bulk and interface properties. These model… Expand

Variational Ansatz for an Abelian to Non-Abelian Topological Phase Transition in ν=1/2+1/2 Bilayers.
A one-parameter variational ansatz is proposed to describe the tunneling-driven Abelian to non-Abelian transition in bosonic ν= 1/2+1/2 fractional quantum Hall bilayers and to engineer the interlayer tunneling to create an interface trapping a neutral chiral Majorana fermion. Expand

Fractional quantum Hall phase transitions and four-flux states in graphene.
Local electronic compressibility measurements of ultraclean suspended graphene reveal a multitude of fractional quantum Hall states surrounding filling factors ν=-1/2 and -1/4, and several of these states exhibit phase transitions that indicate abrupt changes in the underlying order. Expand
