Kavli Affiliate: Archana Raja| Summary:Achieving ultra-low thermal conductivity under ambient conditions is a fundamental challenge constrained by classical heat transport limits and material design trade-offs. Here, we introduce a new class of nano-bubble wrap architectures that achieve exceptionally low thermal conductivity by integrating nanoscale gas confinement with atomically thin, weakly coupled van der Waals solids. […]

Vogelstein | Summary: Sex classification using neuroimaging data has the potential to revolutionize personalized diagnostics by revealing subtle structural brain differences that underlie sex-specific disease risks. Despite the promise of machine […]
Kavli Affiliate: James Analytis| Summary:The cobalt-intercalated transition metal dichalcogenide Co$_x$TaS$_2$ hosts a rich landscape of magnetic phases that depend sensitively on $x$. While the stoichiometric compound with $x=1/3$ exhibits a single magnetic transition, samples with $xleq 0.325$ display two transitions with an anomalous Hall effect (AHE) emerging in the lower temperature phase. Here, we resolve […]
Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:We recently measured the branching fraction of the $B^+rightarrow K^+νbarν$ decay using 362fb$^-1$ 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 and maximize the scientific impact of […]
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 […]
Kavli Affiliate: Satoshi Shirai | 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 the gravitational wave (GW) background observed by recent pulsar timing array […]
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 […]
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 […]
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 […]
Kavli Affiliate: J. S. Villasenor | Summary:We analyze from a geometric perspective the Hamiltonian formulation of a recent modification of the Husain-Kuchař model where, while preserving the connection as a dynamical variable, the other field is restricted to be the exterior covariant derivative of a Lie algebra-valued function. We prove that 3-dimensional diffeomorphisms can be […]
