We have investigated the quantum dynamics of two ultracold bosons inside anatomic waveguide for two different confinement geometries (cigar-shaped andtoroidal waveguides) by quantum Monte Carlo methods. For quasi-1D gases, theconfining potential of the waveguide leads to the so-called confinement inducedresonance (CIR), results in the phase transition of the gas to the impenetrablebosonic regime (known as TG gas). In this regime the bosons repel each otherstrongly and behave like fermions. We reproduce CIR for a cigar-shapedwaveguide and analyze the behavior of the system for different conditions.Moreover, our analysis demonstrates appearance of CIR for a toroidal waveguide.Particularly, we show that the resonance position is dependent on the size ofthe waveguide, which is in contrast to the cigar shaped waveguides for which itis universal.
