Effective continuum models for the buckling of non-periodic architected sheets that display quasi-mechanism behaviors

Posted by July 4, 2021Uncategorized

Kavli Affiliate: Chiara Daraio | First 5 Authors: Connor McMahan, Andrew Akerson, Paolo Celli, Basile Audoly, Chiara Daraio | Summary: In this work, we construct an effective continuum model for architected sheets that are composed of bulky tiles connected by slender elastic joints. Due to their mesostructure, these sheets feature quasi-mechanisms — low-energy local kinematic […]

A shock near the virial radius of the Perseus Cluster

Posted by klaurent July 4, 2021Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Zhenlin Zhu, Aurora Simionescu, Hiroki Akamatsu, Xiaoyuan Zhang, Jelle S. Kaastra | Summary: Previous X-ray studies of the Perseus Cluster, consisting of 85 Suzaku pointings along eight azimuthal directions, revealed a particularly steep decrease in the projected temperature profile near the virial radius (~r200) towards the […]

Investigating magnetically-induced distortions of neutron stars through gamma-ray burst X-ray plateaus

Posted by klaurent July 3, 2021Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Weihua Wang, Shujin Hou, Renxin Xu | Summary: Magnetic field may distort neutron stars (NSs), but its effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. Part of gamma-ray bursts (GRBs) are […]

Kavli Affiliate: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Renxin Xu, , | Summary: Magnetic field may distort neutron stars (NSs), but the effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. The central objects of Gamma-ray bursts (GRBs) could be […]

Tunable strong coupling of mechanical resonance between spatially separated FePS$_3$ nanodrums

Posted by klaurent July 2, 2021Delft

Kavli Affiliate: Herre S. J. Van Der Zant | First 5 Authors: Makars Šiškins, Ekaterina Sokolovskaya, Martin Lee, Samuel Mañas-Valero, Dejan Davidovikj | Summary: Coupled nanomechanical resonators made of two-dimensional materials are promising for processing information with mechanical modes. However, the challenge for these types of systems is to control the coupling. Here, we demonstrate […]

Lattice Renormalization of Quantum Simulations

Posted by klaurent July 2, 2021Chicago

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: With advances in quantum computing, new opportunities arise to tackle challenging calculations in quantum field theory. We show that trotterized time-evolution operators can be related by analytic continuation to the Euclidean transfer matrix on an anisotropic lattice. […]

Neutrino constraints on long-lived heavy dark sector particle decays in the Earth

Posted by klaurent July 2, 2021Chicago

Kavli Affiliate: Angela V. Olinto | First 5 Authors: Mary Hall Reno, Luis A. Anchordoqui, Atri Bhattacharya, Austin Cummings, Johannes Eser | Summary: Recent theoretical work has explored dark matter accumulation in the Earth and its drift towards the center of the Earth that, for the current age of the Earth, does not necessarily result […]

Posted by klaurent July 2, 2021Stanford

Kavli Affiliate: R. Morris | First 5 Authors: R. Abuter, A. Amorim, M. Bauböck, F. Baganoff, J. P. Berge | Summary: We report the time-resolved spectral analysis of a bright near-infrared and moderate X-ray flare of Sgr A*. We obtained light curves in the $M$-, $K$-, and $H$-bands in the mid- and near-infrared and in […]
