Authors: Paulisch, V; Perarnau-Llobet, M.; Gonzalez-Tudela, A.; Cirac, J., I Contribution: Article Journal: PHYSICAL REVIEW A Publication date: 2019/04/08 DOI: 10.1103/PhysRevA.99.043807 Abstract: Photonic states with large and fixed photon numbers, such as Fock states, enable quantum-enhanced metrology but remain an experimentally elusive resource. A potentially simple, deterministic, and scalable way to generate these states consists of [...]

Graphene multi-protonation: A cooperative mechanism for proton permeation

2020-01-16T12:54:25+01:00Tags: , , |

Authors: Bartolomei, Massimiliano; Hernandez, Marta, I; Campos-Martinez, Jose; Hernandez-Lamoneda, Ramon Contribution: Article Journal: CARBON Publication date: 2019/04/07 DOI: 10.1016/j.carbon.2018.12.086 Abstract: The interaction between protons and graphene is attracting a large interest due to recent experiments showing that these charged species permeate through the 2D material following a low barrier (similar to 0.8 eV) activated process. A [...]
