Query: Unified description of $^6$Li structure and deuterium-$^4$He dynamics
  with chiral two- and three-nucleon forces   Prototype for the study of weakly bound projectiles colliding on stable
targets, the scattering of deuterium ($d$) on $^4$He ($\alpha$) is an important
milestone in the search for a fundamental understanding of low-energy
reactions. At the same time, it is also important for its role in the Big-bang
nucleosynthesis of $^6$Li and applications in the characterization of deuterium
impurities in materials. We present the first unified {\em ab initio} study of
the $^6$Li ground state and $d$-$^4$He elastic scattering using two- and
three-nucleon forces derived within the framework of chiral effective field
theory. The six-nucleon bound-state and scattering observables are calculated
by means of the no-core shell model with continuum. %and are compared to
available experimental data. We analyze the influence of the dynamic
polarization of the deuterium and of the chiral three-nucleon force, and
examine the role of the continuum degrees of freedom in shaping the low-lying
spectrum of $^6$Li. We find that the adopted Hamiltonian correctly predicts the
binding energy of $^6$Li, yielding an asymptotic $D$- to $S$-state ratio of the
$^6$Li wave function in $d+\alpha$ configuration of $-0.027$ in agreement with
the value determined from a phase shift analysis of $^6$Li+$^4$He elastic
scattering, but overestimates the excitation energy of the first $3^+$ state by
$350$ keV. The bulk of the computed differential cross section is in good
agreement with data.
