Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Chengying Bao, Myoung-Gyun Suh, Boqiang Shen, Kemal Şafak, Anan Dai | Summary: Coherently-pumped (Kerr) solitons in an ideal optical microcavity are expected to undergo random quantum motion that determines fundamental performance limits in applications of soliton microcombs. Here, this diffusive motion and its impact on Kerr […]
Kavli Affiliate: Richard Mittleman | First 5 Authors: Michael P. Ross, Krishna Venkateswara, Conor Mow-Lowry, Sam Cooper, Jim Warner | Summary: Modern gravitational-wave observatories require robust low-frequency active seismic isolation in order to keep the interferometer at its ideal operating conditions. Seismometers are used to measure both the motion of the ground and isolated platform. […]

Kavli Affiliate: Donald G. York | First 5 Authors: David V. Bowen, Todd M. Tripp, Edward B. Jenkins, Max Pettini, Doron Chelouche | Summary: We present an HST Cosmic Origins Spectrograph (COS) spectrum of the QSO SDSS J095109.12+330745.8 ($z_{em} = 0.645$) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ($M_B = -16.0$, $cz […]
Kavli Affiliate: Robert F. Goeke | First 5 Authors: Ian Wong, Avi Shporer, Tansu Daylan, Björn Benneke, Tara Fetherolf | Summary: We present a systematic phase curve analysis of known transiting systems observed by the Transiting Exoplanet Survey Satellite (TESS) during year one of the primary mission. Using theoretical predictions for the amplitude of the […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Rui Luo, Yunpeng Men, Kejia Lee, Weiyang Wang, D. R. Lorimer | Summary: The luminosity function of Fast Radio Bursts (FRBs), defined as the event rate per unit cosmic co-moving volume per unit luminosity, may help to reveal the possible origins of FRBs and design the optimal […]
Kavli Affiliate: David Spergel | First 5 Authors: Miles Cranmer, Sam Greydanus, Stephan Hoyer, Peter Battaglia, David Spergel | Summary: Accurate models of the world are built upon notions of its underlying symmetries. In physics, these symmetries correspond to conservation laws, such as for energy and momentum. Yet even though neural network models see increasing […]
Kavli Affiliate: Leonardo Dicarlo | First 5 Authors: Xiang Zou, Shavindra P. Premaratne, M. Adriaan Rol, Sonika Johri, Viacheslav Ostroukh | Summary: Quantum computers with tens to hundreds of noisy qubits are being developed today. To be useful for real-world applications, we believe that these near-term systems cannot simply be scaled-down non-error-corrected versions of future […]
Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Nathan Benjamin, Hirosi Ooguri, Shu-Heng Shao, Yifan Wang, | Summary: We show that every compact, unitary two-dimensional CFT with an abelian conserved current has vanishing twist gap for charged primary fields with respect to the $mathfrak{u}(1)times$Virasoro algebra. This means that either the chiral algebra is enhanced by […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Xiangrui Li, Xin Li, Deng Pan, Dongxiao Zhu, | Summary: Deep convolutional neural networks (CNNs) trained with logistic and softmax losses have made significant advancement in visual recognition tasks in computer vision. When training data exhibit class imbalances, the class-wise reweighted version of logistic and softmax […]
