Fert and P. Gr\\\"ungerg's discovery of the giant magnetoresistivity. Since, the spin-dependent electrical injection has found useful applications in storage devices, but fully operational spin-dependent semiconductor electronics remain a challenging task because of weak spin-orbit couplings and/or strong spin relaxations. These limitations are lifted considering atoms instead of electrons or holes as spin carriers. In this emerging field of atomtronics, we demonstrate the equivalent of a Datta-Das transistor using a degenerate fermi gas of strontium atoms as spin carriers in interaction with a tripod laser-beams scheme. We explore the dependence of spin rotation, and we identify two key control parameters which we interpret as equivalent to the gate-source and drain-source voltages of a field effect transistor. Our finding broadens the spectrum of atomtronics devices for implementation of operational spin-sensitive circuits.", "revisions": [ { "version": "v1", "updated": "2022-03-18T03:42:27.000Z" } ], "analyses": { "keywords": [ "artificial gauge fields", "datta-das transistor", "atomtronic circuits", "operational spin-dependent semiconductor electronics remain", "fully operational spin-dependent semiconductor electronics" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
