Kinetics of Vacancy-Assisted Reversible Phase Transition in Monolayer MoTe$_2$

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Fei Shuang, Fei Shuang, , , | Summary: We investigate the kinetics of phase transition between the 2H and 1T$^prime$ phases in monolayer MoTe$_2$ using atomistic simulations based on a machine learning interatomic potential trained on SCAN-DFT data, combined with mean field kinetic theory to interpret the […]

BASS LIII: The Eddington Ratio as the Primary Regulator of the Fraction of X-ray Emission in Active Galactic Nuclei

Posted by klaurent Peking

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kriti Kamal Gupta, Kriti Kamal Gupta, , , | Summary: Active galactic nuclei (AGN) emit radiation via accretion across the entire energy spectrum. While the standard disk and corona model can somewhat describe this emission, it fails to predict specific features such as the soft X-ray excess, […]

A model-agnostic likelihood for the reinterpretation of the $boldsymbolB^+to K^+ νbarν$ measurement at Belle II

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, Belle II Collaboration, , , | Summary: We recently measured the branching fraction of the $B^+rightarrow K^+nubarnu$ decay using 362 fb$^-1$ of on-resonance $e^+e^-$ collision data, under the assumption of Standard Model kinematics, providing the first evidence for this decay. To facilitate future reinterpretations […]

Do Cosmic String Segments Emit Gravitational Waves?

Posted by klaurent Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Akifumi Chitose, Akifumi Chitose, , , | Summary: Cosmic strings are predicted in various extensions of the Standard Model, including grand unified theories. Depending on the symmetry-breaking pattern, they can be either topologically stable or metastable. Intriguingly, metastable strings have been proposed as a possible origin of […]

Text-driven Multiplanar Visual Interaction for Semi-supervised Medical Image Segmentation

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Kaiwen Huang, Kaiwen Huang, , , | Summary: Semi-supervised medical image segmentation is a crucial technique for alleviating the high cost of data annotation. When labeled data is limited, textual information can provide additional context to enhance visual semantic understanding. However, research exploring the use of textual […]

First Constraints from Marked Angular Power Spectra with Subaru Hyper Suprime-Cam Survey First-Year Data

Posted by klaurent Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jessica A. Cowell, Jessica A. Cowell, , , | Summary: We present the first application of marked angular power spectra to weak lensing data, using maps from the Subaru Hyper Suprime-Cam Year 1 (HSC-Y1) survey. Marked convergence fields, constructed by weighting the convergence field with non-linear functions […]

Emergent Symmetry and Phase Transitions on the Domain Wall of $mathbbZ_2$ Topological Orders

Posted by klaurent UCAS

Kavli Affiliate: Long Zhang | First 5 Authors: Hong-Hao Song, Hong-Hao Song, , , | Summary: The one-dimensional (1D) domain wall of 2D $mathbbZ_2$ topological orders is studied theoretically. The Ising domain wall model is shown to have an emergent SU(2)$_1$ conformal symmetry because of a hidden nonsymmorphic octahedral symmetry. While a weak magnetic field […]

Measurement-Induced Phase Transition in a Disordered XX Spin Chain: A Real-Space Renormalization Group Study

Posted by klaurent Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Siddharth Tiwary, Siddharth Tiwary, , , | Summary: Spin chains with quenched disorder exhibit rich critical behavior, often captured by real-space renormalization group (RSRG) techniques. However, the physics of such systems in the presence of random measurements (i.e., non-Hermitian dephasing) remains largely unexplored. The interplay between […]
