Query: Spontaneous Layer-Pseudospin Domain Walls in Bilayer Graphene   Bilayer graphene is susceptible to a family of unusual broken symmetry states
with spin and valley dependent layer polarization. We report on a microscopic
study of the domain walls in these systems, demonstrating that they have
interesting microscopic structures related to order-induced topological
characters. We use our results to estimate Ginzburg-Landau model parameters and
transition temperatures for the ordered states of bilayer graphene.
