Query: Separation induced resonances in quasi-one-dimensional ultracold atomic
  gases   We study the effective one-dimensional (1D) scattering of two distinguishable
atoms confined individually by {\em separated} transverse harmonic traps. With
equal trapping frequency for two s-wave interacting atoms, we find that by
tuning the trap separations, the system can undergo {\em double} 1D scattering
resonance, named as the separation induced resonance(SIR), when the ratio
between the confinement length and s-wave scattering length is within
$(0.791,1.46]$. Near SIR, the scattering property shows unique dependence on
the resonance position. The universality of a many-body system on scattering
branch near SIR is demonstrated by studying the interaction effect of a
localized impurity coupled with a Fermi sea of light atoms in a quasi-1D trap.
