Query: Harnessing synthetic gauge fields for maximally entangled state
  generation   We study the generation of entanglement between two species of neutral cold
atoms living on an optical ring lattice, where each group of particles can be
described by a $d$-dimensional Hilbert space (qu$d$it). Synthetic magnetic
fields are exploited to create an entangled state between the pair of qu$d$its.
Maximally entangled eigenstates are found for well defined values of the
Aharonov-Bohm phase, which are zero energy eigenstates of both the kinetic and
interacting parts of the Bose-Hubbard Hamiltonian, making them quite
exceptional and robust against certain non-perturbative fluctuations of the
Hamiltonian. We propose a protocol to reach the maximally entangled state (MES)
by starting from an initially prepared ground state. Also, an indirect method
to detect the MES by measuring the current of the particles is proposed.
