Estimating the effective lifetime of the $zsim6$ quasar population from the composite proximity zone profile

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 […]

Gravitational wave propagation beyond general relativity: waveform distortions and echoes

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 […]

High-fidelity three-qubit iToffoli gate for fixed-frequency superconducting qubits

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 […]

Toroidal and Elliptic Quiver BPS Algebras and Beyond

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 […]

Event Extraction by Associating Event Types and Argument Roles

Kavli Affiliate: Lihong Wang | First 5 Authors: Qian Li, Shu Guo, Jia Wu, Jianxin Li, Jiawei Sheng | Summary: Event extraction (EE), which acquires structural event knowledge from texts, can be divided into two sub-tasks: event type classification and element extraction (namely identifying triggers and arguments under different role patterns). As different event types […]

Anarchic Federated Learning

Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Xin Zhang, Prashant Khanduri, Jia Liu, | Summary: Present-day federated learning (FL) systems deployed over edge networks consists of a large number of workers with high degrees of heterogeneity in data and/or computing capabilities, which call for flexible worker participation in terms of timing, effort, […]

Cosmic birefringence tomography and calibration-independence with reionization signals in the CMB

Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Blake D. Sherwin, Toshiya Namikawa, , , | Summary: The search for cosmic polarization rotation or birefringence in the CMB is well-motivated because it can provide powerful constraints on parity-violating new physics, such as axion-like particles. In this paper we point out that since the CMB polarization […]

Tilted spin current generated by the collinear antiferromagnet RuO2

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Arnab Bose, Nathaniel J. Schreiber, Rakshit Jain, Ding-Fu Shao, Hari P. Nair | Summary: We report measurements demonstrating that when the Neel vector of the collinear antiferromagnet RuO2 is appropriately canted relative to the sample plane, the antiferromagnet generates a substantial out of plane damping-like torque. […]

A 20-Second Cadence View of Solar-Type Stars and Their Planets with TESS: Asteroseismology of Solar Analogs and a Re-characterization of pi Men c

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Daniel Huber, Timothy R. White, Travis S. Metcalfe, Ashley Chontos, Michael M. Fausnaugh | Summary: We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second data compared to […]
