iTHEMS Theoretical Physics Seminar by Kensuke Kakimoto on July 23, 2025

In this seminar, mesoscopic transport between a one-dimensional chain with two-body loss, which is realizable with ultracold atoms, is discussed. Based on the Keldysh Green’s function formalism in combination with a noise-field representation of Lindblad dynamics, the obtained particle current exhibits a weaker suppression compared with that under one-body loss, in agreement with a recent experimental
observation.
