Establishing the Non-Primordial Origin of Black Hole-Neutron Star Mergers

Posted by klaurent October 18, 2021Tokyo

Kavli Affiliate: Misao Sasaki | First 5 Authors: Misao Sasaki, Volodymyr Takhistov, Valeri Vardanyan, Ying-li Zhang, | Summary: Primordial black holes (PBHs) from the early Universe constitute an attractive dark matter candidate. First detections of black hole-neutron star (BH-NS) candidate gravitational wave events by the LIGO/Virgo collaboration, GW200105 and GW200115, already prompted speculations about non-astrophysical […]

Interplay of vibration- and environment-assisted energy transfer

Posted by October 16, 2021Berkeley

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Liwen Ko, Zhibo Yang, Mohan Sarovar, K. Birgitta Whaley | Summary: We study the interplay between two environmental influences on excited state energy transfer in photosynthetic light harvesting complexes, namely, vibrationally assisted energy transfer(VAET) and environment-assisted quantum transport (ENAQT), considering a dimeric chromophore donor-acceptor […]

Universal finite-size amplitude and anomalous entanglement entropy of $z=2$ quantum Lifshitz criticalities in topological chains

Posted by klaurent October 15, 2021Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, T. A. Sedrakyan, , , | Summary: We consider Lifshitz criticalities with dynamical exponent $z=2$ that emerge in a class of topological chains. There, such a criticality plays a fundamental role in describing transitions between symmetry-enriched conformal field theories (CFTs). We report that, at such […]

Charge order and superconductivity in a minimal two-band model for infinite-layer nickelates

Posted by klaurent October 14, 2021UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Hong-Chen Jiang, Brian Moritz, Thomas P. Devereaux, Chunjing Jia | Summary: The recent discovery of superconductivity in infinite-layer nickelates has drawn considerable attention; however, a consensus on the fundamental building blocks and common ingredients necessary to understand and describe their ground states and emergent properties […]

Self-Supervised Learning by Estimating Twin Class Distributions

Posted by klaurent October 14, 2021Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Tao Kong, Rufeng Zhang, Huaping Liu, Hang Li | Summary: We present TWIST, a simple and theoretically explainable self-supervised representation learning method by classifying large-scale unlabeled datasets in an end-to-end way. We employ a siamese network terminated by a softmax operation to produce twin class […]

A disturbing FABLE of mergers, feedback, turbulence, and mass biases in simulated galaxy clusters

Posted by klaurent October 14, 2021Cambridge

Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S. Bennett, Debora Sijacki, , , | Summary: The use of galaxy clusters as cosmological probes often relies on understanding the properties and evolution of the intracluster medium (ICM). However, the ICM is a complex plasma, regularly stirred by mergers and feedback, with non-negligible bulk and […]
