Liquid Crystals as Multifunctional Interfaces for Trapping and Characterizing Microplastics

Kavli Affiliate: Nicholas L. Abbott | First 5 Authors: Fiona Mukherjee, Anye Shi, Xin Wang, Fengqi You, Nicholas L. Abbott | Summary: Identifying and removing microplastics (MPs) from the environment is a global challenge. This study explores how the colloidal fraction of common MPs behave at aqueous interfaces of liquid crystal (LC) films. We observed […]

Superfluid response of an atomically thin, gate-tuned van der Waals superconductor

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Alexander Jarjour, G. M. Ferguson, Brian T. Schaefer, Menyoung Lee, Yen Lee Loh | Summary: A growing number of two-dimensional superconductors are being discovered in the family of layered van der Waals (vdW) materials. Due to small sample volume, their characterization has been largely limited to […]

Detection of a Pair Density Wave State in UTe$_2$

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Qiangqiang Gu, Joseph P. Carroll, Shuqiu Wang, Sheng Ran, Christopher Broyles | Summary: Although UTe$_2$ is a very promising candidate material to embody bulk topological superconductivity, its superconductive order-parameter $Delta(mathbf{k})$ remains unknown. Many diverse forms for $Delta(mathbf{k})$ are physically possible because, in uranium-based heavy fermion […]

Theory of Nb-Zr Alloy Superconductivity and First Experimental Demonstration for Superconducting Radio-Frequency Cavity Applications

Kavli Affiliate: David A. Muller | First 5 Authors: Nathan S. Sitaraman, Zeming Sun, Ben Francis, Ajinkya C. Hire, Thomas Oseroff | Summary: Niobium-zirconium (Nb-Zr) alloy is an old superconductor that is a promising new candidate for superconducting radio-frequency (SRF) cavity applications. Using density-functional and Eliashberg theories, we show that addition of Zr to a […]

Atomic-scale mapping and quantification of local Ruddlesden-Popper phase variations

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: The Ruddlesden-Popper ($A_{n+1}B_{n}text{O}_{3n+1}$) compounds are a highly tunable class of materials whose functional properties can be dramatically impacted by their structural phase $n$. The negligible energetic differences associated with forming a sample with a single value of $n$ versus […]
