The AGORA High-resolution Galaxy Simulations Comparison Project. III: Cosmological zoom-in simulation of a Milky Way-mass halo

Posted by klaurent June 17, 2021Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann, Kentaro Nagamine, Johnny W. Powell | Summary: We present a suite of high-resolution cosmological zoom-in simulations to $z=4$ of a $10^{12},{rm M}_{odot}$ halo at $z=0$, obtained using seven contemporary astrophysical simulation codes widely used in the numerical galaxy formation community. Physics […]

GRUMPY: a simple framework for realistic forward-modelling of dwarf galaxies

Posted by June 17, 2021Chicago

Kavli Affiliate: Andrey Kravtsov | First 5 Authors: Andrey Kravtsov, Viraj Manwadkar, , , | Summary: We present a simple regulator-type framework designed specifically for modelling formation of dwarf galaxies. We explore sensitivity of model predictions for the stellar mass–halo mass and stellar mass–metallicity relations to different modelling choices and parameter values. Despite its simplicity, […]

Divergences in gravitational-wave emission and absorption from extreme mass ratio binaries

Posted by klaurent June 17, 2021MIT

Kavli Affiliate: Scott A. Hughes | First 5 Authors: Enrico Barausse, Emanuele Berti, Vitor Cardoso, Scott A. Hughes, Gaurav Khanna | Summary: A powerful technique to calculate gravitational radiation from binary systems involves a perturbative expansion: if the masses of the two bodies are very different, the "small" body is treated as a point particle […]

Unveiling a critical stripy state in the triangular-lattice SU(4) spin-orbital model

Posted by klaurent June 17, 2021UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Hui-Ke Jin, Rong-Yang Sun, Hong-Hao Tu, Yi Zhou, | Summary: The simplest spin-orbital model can host a nematic spin-orbital liquid state on the triangular lattice. We provide clear evidence that the ground state of the SU(4) Kugel-Khomskii model on the triangular lattice can be well described by […]

The Gravitational-Wave Physics II: Progress

Posted by klaurent June 17, 2021Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Ligong Bian, Rong-Gen Cai, Shuo Cao, Zhoujian Cao, He Gao | Summary: It has been a half-decade since the first direct detection of gravitational waves, which signifies the coming of the era of the gravitational-wave astronomy and gravitational-wave cosmology. The increasing number of the detected gravitational-wave events […]

Phonon Screening of Excitons in Semiconductors: Halide Perovskites and Beyond

Posted by klaurent June 16, 2021Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Marina R. Filip, Jonah B. Haber, Jeffrey B. Neaton, , | Summary: The ab initio Bethe-Salpeter equation (BSE) approach, an established method for the study of excitons in materials, is typically solved in a limit where only static screening from electrons is captured. Here, we generalize […]

SENSEI: Characterization of Single-Electron Events Using a Skipper-CCD

Posted by June 15, 2021Chicago

Kavli Affiliate: Michael Crisler | First 5 Authors: Liron Barak, Itay M. Bloch, Ana Botti, Mariano Cababie, Gustavo Cancelo | Summary: We use a science-grade Skipper Charge Coupled Device (Skipper-CCD) operating in a low-radiation background environment to develop a semi-empirical model that characterizes the origin of single-electron events in CCDs. We identify, separate, and quantify […]

Large tunability of strain in WO3 single-crystal microresonators controlled by exposure to H2 gas

Posted by klaurent June 15, 2021Delft

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Nicola Manca, Giordano Mattoni, Marco Pelassa, Warner J. Venstra, Herre S. J. van der Zant | Summary: Strain engineering is one of the most effective approaches to manipulate the physical state of materials, control their electronic properties, and enable crucial functionalities. Because of their rich phase […]

Controlling Neural Networks with Rule Representations

Posted by klaurent June 14, 2021Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Sungyong Seo, Sercan O. Arik, Jinsung Yoon, Xiang Zhang, Kihyuk Sohn | Summary: We propose a novel training method that integrates rules into deep learning, in a way the strengths of the rules are controllable at inference. Deep Neural Networks with Controllable Rule Representations (DeepCTRL) incorporates a […]
