We theoretically study the dynamics of EP following a coherent split of a one-dimensional harmonic potential in which two interacting bosons are confined. This problem is equivalent to that of an interaction quench between two harmonic oscillators. We show that this simple model captures the bare essentials of EP; that is, each subsystem relaxes to an approx","authors_text":"Eriko Kaminishi, Masahito Ueda, Takashi Mori, Tatsuhiko N.
