Discovery of Dynamical Heterogeneity in a Supercooled Magnetic Monopole Fluid

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Jahnatta Dasini, Chaia Carroll, Chun-Chih Hsu, Hiroto Takahashi, Jack Murphy | Summary: Dynamical heterogeneity, in which transitory local fluctuations occur in the conformation and dynamics of constituent particles, is widely hypothesized to be essential to evolution of supercooled liquids into the glass state. Yet its […]

Adsorption-controlled Growth of Homoepitaxial c-plane Sapphire Films

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Lena N. Majer, Tolga Acartürk, Peter A. van Aken, Wolfgang Braun, Luca Camuti | Summary: Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for adsorption-controlled homoepitaxial growth of c-plane sapphire. […]

Universal scaling solution for a rigidity transition: renormalization group flows near the upper critical dimension

Kavli Affiliate: Itai Cohen | First 5 Authors: Stephen J. Thornton, Danilo B. Liarte, Itai Cohen, James P. Sethna, | Summary: Rigidity transitions induced by the formation of system-spanning disordered rigid clusters, like the jamming transition, can be well-described in most physically relevant dimensions by mean-field theories. However, we lack a theoretical description of these […]
