Query: Microscopic Study of the Halperin - Laughlin Interface through Matrix
  Product States   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 $\nu=1/3$ and a Halperin 332 phase
at filling factor $\nu=2/5$. Based on our recent construction of chiral
topological interfaces in [Nat. Commun. 10, 1860 (2019)], we study a family of
model wavefunctions that captures both the bulk and interface properties. These
model wavefunctions are built within the matrix product state framework. The
validity of our approach is substantiated through extensive comparisons with
exact diagonalization studies. We probe previously unreachable features of the
low energy physics of the transition. We provide, amongst other things, the
characterization of the interface gapless mode and the identification of the
spin and charge excitations in the many-body spectrum. The methods and tools
presented are applicable to a broad range of topological interfaces.
