Development of a bipolar 50 V output digital-to-analog converter system for ion-shuttling operations

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: T. Oshio, R. Nishimoto, T. Higuchi, K. Hayasaka, K. Koike | Summary: The quantum charge-coupled device (QCCD) is one of the notable architectures to achieve large-scale trapped-ion quantum computers. To realize QCCD architecture, ions must be transported quickly while minimizing motional excitation. High-voltage sources are necessary to […]

Relativistic Mott transition in strongly correlated artificial graphene

Posted by dbos Cornell

Kavli Affiliate: Jie Shan | First 5 Authors: Liguo Ma, Raghav Chaturvedi, Phuong X. Nguyen, Kenji Watanabe, Takashi Taniguchi | Summary: The realization of graphene has provided a bench-top laboratory for quantum electrodynamics. The low-energy excitations of graphene are two-dimensional massless Dirac fermions with opposite chiralities at the $pm$K valleys of the graphene Brillouin zone. […]

Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Posted by dbos Columbia

Kavli Affiliate: Liam Paninski | Authors: Stefano Fusi and Liam Paninski | Summary: The brain is highly structured both at anatomical and functional levels. However, within individual brain areas, neurons often exhibit very diverse and seemingly disorganized responses. A more careful analysis shows that these neurons can sometimes be grouped together into specialized subpopulations (categorical […]

How do uncertainties in galaxy formation physics impact field-level galaxy bias?

Posted by dbos Stanford

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Mahlet Shiferaw, Nickolas Kokron, Risa H. Wechsler, , | Summary: Our ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy-dark matter halo relationship for a given galaxy population, which are governed by the intricacies of galaxy formation. To quantify these […]

A comprehensive study of type I (thermonuclear) bursts in the new transient SRGA J144459.2$-$604207

Posted by dbos Peking

Kavli Affiliate: Renxin Xu | First 5 Authors: Tao Fu, Zhaosheng Li, Yuanyue Pan, Long Ji, Yupeng Chen | Summary: We report an analysis of Insight-HXMT observations of the newly discovered accreting millisecond pulsar SRGA J144459.2$-$604207. During the outburst, detected in 2024 February by SRG/ART-XC, the broadband persistent spectrum was well fitted by an absorbed […]
