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: Michael F. Crommie | First 5 Authors: Canxun Zhang, Tiancong Zhu, Salman Kahn, Shaowei Li, Birui Yang | Summary: The discovery of interaction-driven insulating and superconducting phases in moir’e van der Waals heterostructures has sparked considerable interest in understanding the novel correlated physics of these systems. While a significant number of studies have […]
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 […]
Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: We covariantize calculations over the manifold of phase space, establishing Stokes’ theorem for differential cross sections and providing new definitions of familiar observable properties like infrared and collinear safety. Through the introduction of explicit coordinates and a metric […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Daniel Carney, Gordan Krnjaic, David C. Moore, Cindy A. Regal, Gadi Afek | Summary: Numerous astrophysical and cosmological observations are best explained by the existence of dark matter, a mass density which interacts only very weakly with visible, baryonic matter. Searching for the extremely weak signals […]
Kavli Affiliate: Scott A. Hughes | First 5 Authors: Alvin J. K. Chua, Michael L. Katz, Niels Warburton, Scott A. Hughes, | Summary: The future space mission LISA will observe a wealth of gravitational-wave sources at millihertz frequencies. Of these, the extreme-mass-ratio inspirals of compact objects into massive black holes are the only sources that […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The LHCb Collaboration has reported resonant activity in the channel $D^+ K^-$, identifying two components: $X_0(2900)$ with $J^P = 0^+$ at $2866 {pm} 7$ MeV, $Gamma_0=57{pm} 13$ MeV and $X_1(2900)$ with $J^P = 1^-$ at $2904 {pm} […]
Kavli Affiliate: Rainer Spurzem | First 5 Authors: Peter Berczik, Manuel Arca Sedda, Margaryta Sobolenko, Marina Ishchenko, Olexander Sobodar | Summary: In this work we study the stellar-dynamical hardening of unequal mass supermassive black hole (SMBH) binaries in the central regions of galactic nuclei. We present a comprehensive set of direct N-body simulations of the […]
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Kevin Langhoff, Yasunori Nomura, , , | Summary: In understanding the quantum physics of a black hole, nonperturbative aspects of gravity play important roles. In particular, huge gauge redundancies of a gravitational theory at the nonperturbative level, which are much larger than the standard diffeomorphism and relate […]
