Stress tensor mesostructures for freeform shaping of thin substrates

Kavli Affiliate: Youwei Yao | First 5 Authors: Youwei Yao, Brandon Chalifoux, Ralf Heilmann, Mark Schattenburg, | Summary: Stress-induced shaping, which deforms thin substrates utilizing stressed surface coatings, has enabled and enhanced a host of applications in past decades. Owing to the touchless fabrication process compatible with modern planar technology, the method has been applied […]

Revised event rates for extreme and extremely large mass-ratio inspirals

Kavli Affiliate: Xian Chen | First 5 Authors: Verónica Vázquez-Aceves, Lorenz Zwick, Elisa Bortolas, Pedro R. Capelo, Pau Amaro-Seoane | Summary: One of the main targets of the Laser Interferometer Space Antenna (LISA) is the detection of extreme mass-ratio inspirals (EMRIs) and extremely large mass-ratio inspirals (X-MRIs). Their orbits are expected to be highly eccentric […]

Entropy-Conserving Scheme for Modeling Nonthermal Energies in Fluid Dynamics Simulations

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Vadim A. Semenov, Andrey V. Kravtsov, Benedikt Diemer, , | Summary: We compare the performance of energy-based and entropy-conservative schemes for modeling nonthermal energy components, such as unresolved turbulence and cosmic rays, using idealized fluid dynamics tests and isolated galaxy simulations. While both methods are aimed […]

Mechanical Cloak via Data-Driven Aperiodic Metamaterial Design

Kavli Affiliate: Chiara Daraio | First 5 Authors: Liwei Wang, Jagannadh Boddapati, Ke Liu, Ping Zhu, Chiara Daraio | Summary: Mechanical cloaks are materials engineered to manipulate the elastic response around objects to make them indistinguishable from their homogeneous surroundings. Typically, methods based on material-parameter transformations are used to design optical, thermal and electric cloaks. […]

A full spectral-timing model to map the accretion flow in black hole binaries: the low/hard state of MAXI J1820+070

Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Tenyo Kawamura, Magnus Axelsson, Chris Done, Tadayuki Takahashi, | Summary: The nature and geometry of the accretion flow in the low/hard state of black hole binaries is currently controversial. While most properties are generally explained in the truncated disc/hot inner flow model, the detection of a broad […]
