--- _id: '10401' abstract: - lang: eng text: Theoretical and experimental studies of the interaction between spins and temperature are vital for the development of spin caloritronics, as they dictate the design of future devices. In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect. acknowledgement: The authors acknowledge support from the European QuantERA ERA-NET Cofund in Quantum Technologies (Project QTFLAG Grant Agreement No. 731473) (R.E.B), CNPq (Conselho Nacional de Desenvolvimento Científico e Tecnológico) Brazil (A.F.), the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 754411 (A.G.V.), the Independent Research Fund Denmark, the Carlsberg Foundation, and Aarhus University Research Foundation under the Jens Christian Skou fellowship program (N.T.Z). article_number: '252' article_processing_charge: No article_type: original author: - first_name: Rafael E. full_name: Barfknecht, Rafael E. last_name: Barfknecht - first_name: Angela full_name: Foerster, Angela last_name: Foerster - first_name: Nikolaj T. full_name: Zinner, Nikolaj T. last_name: Zinner - first_name: Artem full_name: Volosniev, Artem id: 37D278BC-F248-11E8-B48F-1D18A9856A87 last_name: Volosniev orcid: 0000-0003-0393-5525 citation: ama: Barfknecht RE, Foerster A, Zinner NT, Volosniev A.
