Symmetry-protected topological order identified via Gutzwiller-guided density-matrix-renormalization-group: $mathrmSO(n)$ spin chains

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: , , , , | Summary: We present a comprehensive study of topological phases in the SO($n$) spin chains using a combination of analytical parton construction and numerical techniques. For even $n=2l$, we identify a novel SPT$^2$ phase characterized by two distinct topological sectors, exhibiting exact degeneracy […]

Massive Black Hole Seed Formation in Strong X-ray Environments at High Redshift

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kazutaka Kimura, Kazutaka Kimura, , , | Summary: Direct collapse of pristine gas in early galaxies is a promissing pathway for forming supermassive black holes (BHs) powering active galactic nuclei (AGNs) at the epoch of reionization (EoR). This seeding mechanism requires suppression of molecular hydrogen (H$_2$) cooling […]

Cosmogenic Neutrino Point Source and KM3-230213A

Posted by klaurent Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Qinyuan Zhang, Qinyuan Zhang, , , | Summary: Cosmogenic neutrinos (CNs) are produced by ultra-high energy cosmic rays (UHECRs) interacting with cosmic background radiation. We investigated the properties of CN point/extended sources, i.e, the neutrino spectrum, and angular profile as functions of time, by assuming that UHECR […]

GenEDA: Towards Generative Netlist Functional Reasoning via Cross-Modal Circuit Encoder-Decoder Alignment

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Wenji Fang, Wenji Fang, , , | Summary: The success of foundation AI has motivated the research of circuit foundation models, which are customized to assist the integrated circuit (IC) design process. However, existing pre-trained circuit foundation models are typically limited to standalone encoders for predictive tasks […]

Error-In-Variables Methods for Efficient System Identification with Finite-Sample Guarantees

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Yuyang Zhang, Yuyang Zhang, , , | Summary: This paper addresses the problem of learning linear dynamical systems from noisy observations. In this setting, existing algorithms either yield biased parameter estimates or have large sample complexities. We resolve these issues by adapting the instrumental variable method and […]

Towards a Digital Twin of Noisy Quantum Computers: Calibration-Driven Emulation of Transmon Qubits

Posted by klaurent Chicago

Kavli Affiliate: Elise Jennings | First 5 Authors: Ronny Müller, Ronny Müller, , , | Summary: We develop a parametric error model to construct a digital twin of a superconducting transmon qubit device. The model parameters are extracted from hardware calibration data and supplementary benchmarking circuits, providing a dynamic, system-specific representation of noise and gate […]

Disk-jet coupling across the spectral transition in supermassive black holes

Posted by klaurent Tokyo

Kavli Affiliate: John D. Silverman | First 5 Authors: Jia-Lai Kang, Jia-Lai Kang, , , | Summary: Accretion flows in both stellar and supermassive black holes show a distinct spectral transition. This is seen directly in binaries and changing look AGN, and also in a recent sample of eROSITA X-ray selected, unobscured AGN where the […]
