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

Posted by dbos Peking

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, […]

Photometric Selection of Unobscured QSOs in the Ecliptic Poles: KMTNet in the South Field and Pan-STARRS in the North Field

Posted by klaurent Peking

Kavli Affiliate: Luis C. Ho | First 5 Authors: Woowon Byun, Minjin Kim, Yun-Kyeong Sheen, Dongseob Lee, Luis C. Ho | Summary: We search for quasi-stellar objects (QSOs) in a wide area of the south ecliptic pole (SEP) field, which has been and will continue to be intensively explored through various space missions. For this […]

Sub-second periodic radio oscillations in a microquasar

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Pengfu Tian, Ping Zhang, Wei Wang, Pei Wang, Xiaohui Sun | Summary: Powerful relativistic jets are one of the ubiquitous features of accreting black holes in all scales. GRS 1915+105 is a well-known fast-spinning black-hole X-ray binary with a relativistic jet, termed as a “microquasar”, as indicated […]

How Does Diffusion Influence Pretrained Language Models on Out-of-Distribution Data?

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Huazheng Wang, Daixuan Cheng, Haifeng Sun, Jingyu Wang, Qi Qi | Summary: Transformer-based pretrained language models (PLMs) have achieved great success in modern NLP. An important advantage of PLMs is good out-of-distribution (OOD) robustness. Recently, diffusion models have attracted a lot of work to apply diffusion to […]

Reinforcement Learning for Sequential Decoding of Generalized LDPC Codes

Posted by Chicago

Kavli Affiliate: Salman Habib | First 5 Authors: Salman Habib, David G. M. Mitchell, , , | Summary: In this work, we propose reinforcement learning (RL) for sequential decoding of moderate length generalized low-density parity-check (GLDPC) codes. Here, sequential decoding refers to scheduling all the generalized constraint nodes (GCNs) and single parity-check nodes (SPCNs) of […]

Flat-sky Angular Power Spectra Revisited

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Challinor | First 5 Authors: Zucheng Gao, Zvonimir Vlah, Anthony Challinor, , | Summary: We revisit the flat-sky approximation for evaluating the angular power spectra of projected random fields by retaining information about the correlations along the line of sight. With broad, overlapping radial window functions, these line-of-sight correlations are suppressed and […]
