Tunable vortex Majorana modes controlled by strain in homogeneous LiFeAs

Posted by dbos UCAS

Kavli Affiliate: Fuchun Zhang | First 5 Authors: Wenyao Liu, Quanxin Hu, Xiancheng Wang, Yigui Zhong, Fazhi Yang | Summary: The iron-based superconductors (FeSCs) have recently emerged as a promising single-material Majorana platform by hosting isolated Majorana zero modes (MZMs) at relatively high temperatures. To further verify its Majorana nature and move forward to build […]

MuA-Ori: Multimodal Actuated Origami

Posted by klaurent Harvard

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Antonio Elia Forte, David Melancon, Leon M. Kamp, Benjamin Gorissen, Katia Bertoldi | Summary: Recently, inflatable elements integrated in robotics systems have enabled complex motions as a result of simple inputs. However, these fluidic actuators typically exhibit unimodal deformation upon inflation. Here, we present a new design […]

The deepest $Chandra$ view of RBS 797: evidence for two pairs of equidistant X-ray cavities

Posted by klaurent MIT

Kavli Affiliate: Michael McDonald | First 5 Authors: Francesco Ubertosi, Myriam Gitti, Fabrizio Brighenti, Gianfranco Brunetti, Michael McDonald | Summary: We present the first results of a deep $Chandra$ observation of the galaxy cluster RBS 797, whose previous X-ray studies revealed two pronounced X-ray cavities in the east-west (E-W) direction. Follow-up VLA radio observations of […]

An Edge-On Orbit for the Eccentric Long-Period Planet HR 5183 b

Posted by klaurent MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Alexander Venner, Logan A. Pearce, Andrew Vanderburg, , | Summary: The long-period giant planet HR 5183 b has one of the most extreme orbits among exoplanets known to date. In this work we use Hipparcos-Gaia astrometry to measure the orbital inclination of this planet for the first […]

Ultrafast optical excitation of magnetic dynamics in van der Waals magnets: Coherent magnons and BKT dynamics in NiPS$_3$

Posted by klaurent UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Urban F. P. Seifert, Mengxing Ye, Leon Balents, , | Summary: Optical pump-probe experiments carried out in the time domain reveal both the intrinsic low energy dynamics and its connections to higher energy excitations in correlated electron systems. In this work, we propose two microscopic mechanisms for […]

Bridging the Gap: Categorizing Gravitational-Wave Events at the Transition Between Neutron Stars and Black Holes

Posted by klaurent Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Maya Fishbach, Reed Essick, Daniel E. Holz, Shanika Galaudage | Summary: We search for features in the mass distribution of detected compact binary coalescences which signify the transition between neutron stars and black holes. We analyze all gravitational wave detections by LIGO-Virgo made […]
