We study the ground-state phase diagram of two-dimensional two-component (or pseudospin-1/2) Bose gases in a high synthetic magnetic field in the space of the total filling factor and the ratio of the intercomponent coupling $g_{\uparrow\downarrow}$ to the intracomponent one $g>0$. Using exact diagonalization, we find that when the intercomponent coupling is attractive ($g_{\uparrow\downarrow}<0$), the product states of a pair of nearly uncorrelated quantum Hall states are remarkably robust and… Expand

Variational Ansatz for an Abelian to Non-Abelian Topological Phase Transition in ν=1/2+1/2 Bilayers.
TLDR
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
