Ultra-high-resolution imaging of moiré lattices and superstructures using scanning microwave impedance microscopy under ambient conditions

Posted by klaurent Berkeley

Kavli Affiliate: Michael Crommie | First 5 Authors: Kyunghoon Lee, M. Iqbal Bakti Utama, Salman Kahn, Appalakondaiah Samudrala, Nicolas Leconte | Summary: Two-dimensional heterostructures with layers of slightly different lattice vectors exhibit a new periodic structure known as moire lattices. Moire lattice formation provides a powerful new way to engineer the electronic structure of two-dimensional […]

A model for the fragmentation kinetics of crumpled thin sheets

Posted by klaurent Harvard

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Jovana Andrejevic, Lisa M. Lee, Shmuel M. Rubinstein, Chris H. Rycroft, | Summary: As a confined thin sheet crumples, it spontaneously segments into flat facets delimited by a network of ridges. Despite the apparent disorder of this process, statistical properties of crumpled sheets exhibit striking reproducibility. […]

Josephson current via an isolated Majorana zero mode

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Bernard van Heck, Michael Wimmer, , | Summary: We study the equilibrium dc Josephson current in a junction between an $s$-wave and a topological superconductor. Cooper pairs from the $s$-wave superconducting lead can transfer to the topological side either via an unpaired Majorana zero mode […]

Spectral and spatial isolation of single WSe$_2$ quantum emitters using hexagonal boron nitride wrinkles

Posted by klaurent Cornell

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Raphaël S. Daveau, Tom Vandekerckhove, Arunabh Mukherjee, Zefang Wang, Jie Shan | Summary: Monolayer WSe$_2$ hosts bright single-photon emitters. Because of its compliance, monolayer WSe$_2$ conforms to patterned substrates without breaking, thus creating the potential for large local strain, which is one activation mechanism of its […]

Phase-Space Spectral Line De-confusion in Intensity Mapping

Posted by klaurent Caltech

Kavli Affiliate: James J. Bock | First 5 Authors: Yun-Ting Cheng, Tzu-Ching Chang, James J. Bock, , | Summary: Line intensity mapping (LIM) is a promising tool to efficiently probe the three-dimensional large-scale structure by mapping the aggregate emission of a spectral line from all sources that trace the matter density field. Spectral lines from […]
