Exact Results for Tunneling Problems of Bogoliubov Excitations in the Critical Supercurrent State
Daisuke Takahashi, Yusuke Kato
We show the exact solution of Bogoliubov equations at zero-energy in the critical supercurrent state for arbitrary shape of potential barrier. With use of this solution, we prove t…

Exact Solution of Bogoliubov Equations for Bosons in One-Dimensional Piecewise Constant Potential
Daisuke Takahashi
We show that Bogoliubov equations in one-dimensional systems with piecewise constant potentials can be always solved. In particular, we analyze in detail the case where the condens…
