Fig. 1: Transmission coefficient of BECs in the tunneling problem.
a Schematic picture of the tunneling problem. The blue solid and green dashed curves represent the condensate density ∣ψ0∣2 and the Gaussian barrier. b Calculated transmission coefficient \(| {{{\mathcal{T}}}}{| }^{2}\) as a function of the energy of the incident wave ε for some barrier heights V0. We also show the halfwidths ΔεL and ΔεH for V0/μ = 0.7.
