Continuous gravitational waves from trapped magnetar ejecta and the connection to glitches and antiglitches

Kavli Affiliate: Lijing Shao | First 5 Authors: Garvin Yim, Yong Gao, Yacheng Kang, Lijing Shao, Renxin Xu | Summary: Gravitational waves from isolated sources have eluded detection so far. The upper limit of long-lasting continuous gravitational wave emission is now at the stage of probing physically-motivated models with the most optimistic being strongly constrained. […]

Poly-MOT: A Polyhedral Framework For 3D Multi-Object Tracking

Kavli Affiliate: Ke Wang | First 5 Authors: Xiaoyu Li, Tao Xie, Dedong Liu, Jinghan Gao, Kun Dai | Summary: 3D Multi-object tracking (MOT) empowers mobile robots to accomplish well-informed motion planning and navigation tasks by providing motion trajectories of surrounding objects. However, existing 3D MOT methods typically employ a single similarity metric and physical […]

Selective Manipulation and Tunneling Spectroscopy of Broken-Symmetry Quantum Hall States in a Hybrid-edge Quantum Point Contact

Kavli Affiliate: Ke Wang | First 5 Authors: , , , , | Summary: We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of each broken-symmetry compressible strip in graphene. Via low-temperature magneto-transport measurement, we demonstrate selective manipulation over the evolution, […]
