Authors: Bartolomei, M; Hernández, M. I.; Campos-Martínez, J.; Hernández-Lamoneda, R.; Giorgi, G. Journal: CARBON Publication date: 2021/02/24 DOI: 10.1016/j.carbon.2021.02.056 Abstract: The impermeability of defect-free graphene to all gases has been recently contested since experimental evidence (see Nature 579, 229–232 (2020)) of hydrogen transmission through a two-dimensional carbon layer has been obtained. By means of density [...]

Dissipative Josephson effect in coupled nanolasers

2021-06-17T13:39:41+02:00Tags: , |

Authors: Fernandez-Lorenzo, Samuel; Porras, Diego Journal: NEW JOURNAL OF PHYSICS Publication date: 2021/03/01 DOI: 10.1088/1367-2630/abe811 Abstract: Josephson effects are commonly studied in quantum systems in which dissipation or noise can be neglected or do not play a crucial role. In contrast, here we discuss a setup where dissipative interactions do amplify a photonic Josephson current, [...]
