Marcelo Castellanos2025-04-28T11:14:08+02:00Tags: Multidisciplinary. , Physics|

Authors: Penas, Guillermo F.; Puebla, Ricardo; Garcia-Ripoll, Juan Jose Journal: PHYSICAL REVIEW RESEARCH Publication date: 2024/09/13 DOI: 10.1103/PhysRevResearch.6.033294 Abstract: In this article, we consider a realistic waveguide implementation of a quantum network that serves as a testbed to show how to maximize the storage and manipulation of quantum information in QED setups. We analyze two [...]

Scalable multiphoton generation from cavity-synchronized single-photon sources

Marcelo Castellanos2025-04-28T11:13:54+02:00Tags: Multidisciplinary. , Physics|

Authors: Li, Ming; Garcia-Ripoll, Juan Jose; Ramos, Tomas Journal: PHYSICAL REVIEW RESEARCH Publication date: 2024/09/13 DOI: 10.1103/PhysRevResearch.6.033295 Abstract: We propose an efficient, scalable, and deterministic scheme to generate multiple indistinguishable photons over independent channels, on demand. Our design relies on multiple single-photon sources, each coupled to a waveguide, all interacting with a common cavity mode. [...]

Sodium into ?-Graphyne Multilayers: An Intercalation Compound for Anodes in Metal-Ion Batteries

Marcelo Castellanos2025-04-28T11:13:01+02:00Tags: Materials Science, Multidisciplinary. |

Authors: Bartolomei, Massimiliano; Giorgi, Giacomo Journal: ACS MATERIALS LETTERS Publication date: 2024/09/12 DOI: 10.1021/acsmaterialslett.4c01119 Abstract: The bulk synthesis of gamma-graphyne has been recently achieved and evidenced a multilayered structure, which suggests its potential exploitation as a substitute of graphite-based anode materials for metals heavier than lithium (Li). In fact, each of its regular pores of [...]

Authors: Rojo-Francas, Abel; Isaule, Felipe; Santos, Alan C.; Julia-Diaz, Bruno; Zinner, Nikolaj Thomas Journal: PHYSICAL REVIEW A Publication date: 2024/09/06 DOI: 10.1103/PhysRevA.110.032205 Abstract: We propose a quantum battery realized with a few interacting particles in a three-well system with different on-site energies, which could be realized with ultracold-atom platforms. We prepare the initial state in [...]

Geometrical description and Faddeev-Jackiw quantization of electrical networks
