Topological quantum interference in a pumped Su-Schrieffer-Heeger lattice

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Juan Atalaya, K. Birgitta Whaley, , | Summary: Topological quantum interference emerges from the interplay between quantum mechanics and topology. We present evidence for two types of such interference phenomenon that can result from the quantum dynamics of initial topological states. We realize both […]

Computing the viscous effect in early-time drop impact dynamics

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Shruti Mishra, Shmuel M. Rubinstein, Chris H. Rycroft, , | Summary: The impact of a liquid drop on a solid surface involves many intertwined physical effects, and is influenced by drop velocity, surface tension, ambient pressure and liquid viscosity, among others. Experiments by Kolinski et al. […]

TOI-1518b: A Misaligned Ultra-hot Jupiter with Iron in its Atmosphere

Kavli Affiliate: Edward Morgan | 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 inflated, with $R_p = 1.875pm0.053,R_rm J$, and exhibits several interesting properties, including a misaligned orbit ($240.34^+0.93_-0.98$ degrees) and nearly […]

Towards a Realistic Model of Dark Atoms to Resolve the Hubble Tension

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 […]

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 […]

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 […]

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, […]
