Anomalous tunneling of phonon excitations between two bose-einstein condensates
<p style="text-align:justify;"> We discuss the tunneling of phonon excitations across a potential barrier separating two condensates. It is shown that a strong barrier proves to be transparent for the excitations at low energy ε. Moreover, the transmission is reduced with increasing...
