Kavli Affiliate: Emil J. Martinec | First 5 Authors: Jeffrey A. Harvey, Emil J. Martinec, Rafael I. Nepomechie, , | Summary: This is a preface to A Passion for Theoretical Physics, a special issue collection of articles published in J. Phys. A in memory of Peter G. O. Freund. | Search Query: ArXiv Query: search_query=au:”Emil […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Weixiang Sun, Yang Huang, Haifeng Wang, Chun Wang, Meng Zhang | Summary: Using a sample of nearly 140,000 primary red clump stars selected from the LAMOST and $Gaia$ surveys, we have identified a large sample of "young" [$alpha$/Fe]-enhanced stars with stellar ages younger than 6.0 Gyr and […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Nezhla Aghaei, M. K. Pawelkiewicz, Masahito Yamazaki, , | Summary: The quantization of the Teichm"uller theory has led to the formulation of the so-called Teichm"uller TQFT for 3-manifolds. In this paper we initiate the study of "supersymmetrization" of the Teichm"uller TQFT, which we call the super Teichm"uller […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Mirek Giersz, J. P. Ostriker | Summary: Young dense massive star clusters are a promising environment for the formation of intermediate mass black holes (IMBHs) through collisions. We present a set of 80 simulations carried out with Nbody6++GPU of 10 […]
Kavli Affiliate: Anthony Lasenby | First 5 Authors: Michael Hobson, Anthony Lasenby, , , | Summary: We consider the construction of gauge theories of gravity that are invariant under local conformal transformations. We first clarify the geometric nature of global conformal transformations, in both their infinitesimal and finite forms, and the consequences of global conformal […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Sinéad M. Griffin, Yonit Hochberg, Katherine Inzani, Noah Kurinsky, Tongyan Lin | Summary: We propose the use of silicon carbide (SiC) for direct detection of sub-GeV dark matter. SiC has properties similar to both silicon and diamond, but has two key advantages: (i) it is a polar […]
Kavli Affiliate: Lee McCuller | First 5 Authors: Kentaro Komori, Dhruva Ganapathy, Chris Whittle, Lee McCuller, Lisa Barsotti | Summary: Quantum vacuum fluctuations fundamentally limit the precision of optical measurements, such as those in gravitational-wave detectors. Injection of conventional squeezed vacuum can be used to reduce quantum noise in the readout quadrature, but this reduction […]
Kavli Affiliate: Lisa Barsotti | First 5 Authors: Chris Whittle, Kentaro Komori, Dhruva Ganapathy, Lee McCuller, Lisa Barsotti | Summary: Vacuum quantum fluctuations impose a fundamental limit on the sensitivity of gravitational-wave interferometers, which rank among the most sensitive precision measurement devices ever built. The injection of conventional squeezed vacuum reduces quantum noise in one […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Masahito Yamazaki, , , | Summary: The statistical model of crystal melting represents BPS configurations of D-branes on a toric Calabi-Yau three-fold. Recently it has been noticed that an infinite-dimensional algebra, the quiver Yangian, acts consistently on the crystal-melting configurations. We physically derive the algebra […]
Kavli Affiliate: Naoki Yasuda | First 5 Authors: Ichiro Takahashi, Nao Suzuki, Naoki Yasuda, Akisato Kimura, Naonori Ueda | Summary: The advancement of technology has resulted in a rapid increase in supernova (SN) discoveries. The Subaru/Hyper Suprime-Cam (HSC) transient survey, conducted from fall 2016 through spring 2017, yielded 1824 SN candidates. This gave rise to […]
