Kavli Affiliate: Rainer Spurzem | First 5 Authors: Francesco Paolo Rizzuto, Thorsten Naab, Rainer Spurzem, Manuel Arca-Sedda, Mirek Giersz | Summary: We present direct N-body simulations, carried out with Nbody6++GPU, of young and compact low metallicity star clusters with $1.1times 10^5$ stars, a velocity dispersion of $sim$ 10 $mathrm{km,s^{-1}}$, a half mass radius $R_h=0.6$ pc, […]
Kavli Affiliate: Edward H. Morgan | First 5 Authors: Samuel H. C. Cabot, Aaron Bello-Arufe, João M. Mendonça, René Tronsgaard, Ian Wong | Summary: We present the discovery of TOI-1518b — an ultra-hot Jupiter orbiting a bright star $V = 8.95$. The transiting planet is confirmed using high-resolution optical transmission spectra from EXPRES. It is […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Nikita Blinov, Gordan Krnjaic, Shirley Weishi Li, , | Summary: It has recently been shown that a subdominant hidden sector of atomic dark matter in the early universe can resolve the Hubble tension while maintaining good agreement with most precision cosmological observables. However, such a solution requires […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Michael R. R. Good, Eric V Linder, Frank Wilczek, , | Summary: A new solution for an analytic spectrum of particle creation by an accelerating mirror (dynamical Casimir effect) is given. It is the first model to simultaneously radiate thermally and emit a finite number of particles. […]
Kavli Affiliate: David T. Limmer | First 5 Authors: Nathan Ng, David T. Limmer, Eran Rabani, , | Summary: When deriving exact generalized master equations for the evolution of a reduced set of degrees of freedom, one is free to choose what quantities are relevant by specifying projection operators. However, obtaining a reduced description does […]
Kavli Affiliate: Robert A. Simcoe | First 5 Authors: Karna A. Morey, Anna-Christina Eilers, Frederick B. Davies, Joseph F. Hennawi, Robert A. Simcoe | Summary: The lifetime of quasars can be estimated by means of their proximity zone sizes, which are regions of enhanced flux bluewards of the Lyman-$alpha$ emission line observed in the rest-frame […]
Kavli Affiliate: Wayne Hu | First 5 Authors: Jose Maria Ezquiaga, Wayne Hu, Macarena Lagos, Meng-Xiang Lin, | Summary: We study the cosmological propagation of gravitational waves (GWs) beyond general relativity (GR) across homogeneous and isotropic backgrounds. We consider scenarios in which GWs interact with an additional tensor field and use a parametrized phenomenological approach […]
Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Yosep Kim, Alexis Morvan, Long B. Nguyen, Ravi K. Naik, Christian Jünger | Summary: The development of noisy intermediate-scale quantum (NISQ) devices has extended the scope of executable quantum circuits with high-fidelity single- and two-qubit gates. Equipping NISQ devices with three-qubit gates will enable the realization of […]

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Dmitry Galakhov, Wei Li, Masahito Yamazaki, , | Summary: The quiver Yangian, an infinite-dimensional algebra introduced recently in arXiv:2003.08909, is the algebra underlying BPS state counting problems for toric Calabi-Yau three-folds. We introduce trigonometric and elliptic analogues of quiver Yangians, which we call toroidal quiver algebras and […]
