Using the Sun to Measure the Primary Beam Response of the Canadian Hydrogen Intensity Mapping Experiment

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Anja Boskovic, Jean-François Cliche | Summary: We present a beam pattern measurement of the Canadian Hydrogen Intensity Mapping Experiment (CHIME) made using the Sun as a calibration source. As CHIME is a pure drift scan instrument, we rely on the seasonal […]

Stable pairs and Gopakumar-Vafa type invariants on holomorphic symplectic 4-folds

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yalong Cao, Georg Oberdieck, Yukinobu Toda, , | Summary: As an analogy to Gopakumar-Vafa conjecture on Calabi-Yau 3-folds, Klemm-Pandharipande defined Gopakumar-Vafa type invariants of a Calabi-Yau 4-fold $X$ using Gromov-Witten theory. When $X$ is holomorphic symplectic, Gromov-Witten invariants vanish and one can consider the corresponding reduced theory. […]

High throughput data-driven design of laser crystallized 2D MoS2 chemical sensors

Kavli Affiliate: Xiang Zhang | First 5 Authors: Drake Austin, Paige Miesle, Deanna Sessions, Michael Motala, David Moore | Summary: High throughput characterization and processing techniques are becoming increasingly necessary to navigate multivariable, data-driven design challenges for sensors and electronic devices. For two-dimensional materials, device performance is highly dependent upon a vast array of material […]

Broadband Squeezed Microwaves and Amplification with a Josephson Traveling-Wave Parametric Amplifier

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: Jack Y. Qiu, Arne Grimsmo, Kaidong Peng, Bharath Kannan, Benjamin Lienhard | Summary: Squeezing of the electromagnetic vacuum is an essential metrological technique that is used to reduce quantum noise in applications spanning gravitational wave detection, biological microscopy, and quantum information science. In circuit quantum electrodynamics, squeezed […]
