Universal Vibrational Anharmonicity in Carbyne-like Materials

Autor: Lechner, Johannes M. A., Marabotti, Pietro, Shi, Lei, Pichler, Thomas, Casari, Carlo Spartaco, Heeg, Sebastian

Carbyne, an infinite linear chain of carbon atoms, is the truly one-dimensional allotrope of carbon. While ideal carbyne and its fundamental properties have remained elusive, carbyne-like materials like carbyne chains confined inside carbon nanotubes

Analysis of Thermal Grooving Effects on Vortex Penetration in Vapor-Diffused Nb3Sn

Autor: Lechner, Eric M., Trofimova, Olga, Angle, Jonathan W., DiGuilio, Madison C., Pudasaini, Uttar

While Nb3Sn theoretically offers better superconducting RF cavity performance (Q0 and Eacc) to Nb at any given temperature, peak RF magnetic fields consistently fall short of the 400 mT prediction. The relatively rough topography of vapor-diffused Nb
