Query: Simulating quantum transport with ultracold atoms and interaction
  effects   Quantum transport can be simulated with ultracold atoms by employing spin
superpositions of fermions interacting with spin-dependent potentials. Here we
first extend this scheme to an arbitrary number of spin components so as to
allow simulating transport through a multiterminal quantum dot and derive a
current formula in terms of a spin rotation matrix and potential phase shifts.
We then show that a Fano resonance manifests itself in measuring a linear
conductance at zero temperature in the case of two spin components. We also
study how a weak interparticle interaction in bulk affects quantum transport in
one dimension with the bosonization and renormalization techniques. In
particular, we find that the conductance vanishes for an attractive interaction
due to a bulk spin gap, while it is enhanced for a repulsive interaction by a
power law with lowering the temperature or the chemical potential difference.
