Excitations in the Yang-Gaudin Bose gas
Neil J. Robinson, Robert M. Konik
We study the excitation spectrum of two-component delta-function interacting bosons confined to a single spatial dimension, the Yang-Gaudin Bose gas. We show that there are pronoun…

Motion of a distinguishable impurity in the Bose gas: Arrested expansion without a lattice and impurity snaking
Neil J. Robinson, Jean-Sébastien Caux, Robert M. Konik
We consider the real time dynamics of an initially localized distinguishable impurity injected into the ground state of the Lieb-Liniger model. Focusing on the case where integrabi…
