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 […]

Evidence for magnetic activity at starbirth: a powerful X-ray flare from the Class 0 protostar HOPS 383

Posted by klaurent MIT

Kavli Affiliate: David Principe | First 5 Authors: Nicolas Grosso, Kenji Hamaguchi, David Principe, Joel Kastner, | Summary: Context. Class 0 protostars represent the earliest evolutionary stage of solar-type stars, during which the majority of the system mass resides in an infalling envelope of gas and dust and is not yet in the central, nascent […]

Posted by klaurent Stanford

Kavli Affiliate: C. M. Ignarra | First 5 Authors: D. S. Akerib, C. W. Akerlof, D. Yu. Akimov, A. Alquahtani, S. K. Alsum | Summary: LUX-ZEPLIN (LZ) is a second-generation direct dark matter experiment with spin-independent WIMP-nucleon scattering sensitivity above $1.4 times 10^{-48}$ cm$^{2}$ for a WIMP mass of 40 GeV/c$^{2}$ and a 1000 d […]

Mass loss from massive globular clusters in tidal fields

Posted by klaurent Peking

Kavli Affiliate: Rainer Spurzem | First 5 Authors: Yohai Meiron, Jeremy J. Webb, Jongsuk Hong, Peter Berczik, Rainer Spurzem | Summary: Massive globular clusters lose stars via internal and external processes. Internal processes include mainly two-body relaxation, while external processes include interactions with the Galactic tidal field. We perform a suite of N-body simulations of […]

High-throughput search for magnetic and topological order in transition metal oxides

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Nathan C. Frey, Matthew K. Horton, Jason M. Munro, Sinéad M. Griffin, Kristin A. Persson | Summary: The discovery of intrinsic magnetic topological order in $rm MnBi_2Te_4$ has invigorated the search for materials with coexisting magnetic and topological phases. These multi-order quantum materials are expected to […]

Will LISA Detect Harmonic Gravitational Waves from Galactic Cosmic String Loops?

Posted by klaurent Chicago

Kavli Affiliate: Craig J. Hogan | First 5 Authors: Zimu Khakhaleva-Li, Craig J. Hogan, , , | Summary: Rapid advancement in the observation of cosmic strings has been made in recent years placing increasingly stringent constraints on their properties, with $Gmulesssim 10^{-11}$ from Pulsar Timing Array (PTA). Cosmic string loops with low string tension clump […]

New bounds on macroscopic scalar-field topological defects from non-transient signatures due to environmental dependence and spatial variations of the fundamental constants

Posted by klaurent Tokyo

Kavli Affiliate: Yevgeny V. Stadnik | First 5 Authors: Yevgeny V. Stadnik, , , , | Summary: We point out that in models of macroscopic topological defects composed of one or more scalar fields that interact with standard-model fields via scalar-type couplings, the back-action of ambient matter on the scalar field(s) produces an environmental dependence […]

Automated Measurements of Key Morphological Features of Human Embryos for IVF

Posted by klaurent Harvard

Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D. Leahy, Won-Dong Jang, Helen Y. Yang, Robbert Struyven, Donglai Wei | Summary: A major challenge in clinical In-Vitro Fertilization (IVF) is selecting the highest quality embryo to transfer to the patient in the hopes of achieving a pregnancy. Time-lapse microscopy provides clinicians with a wealth […]
