Emittance Minimization for Aberration Correction I: Aberration correction of an electron microscope without knowing the aberration coefficients

Posted by dbos December 29, 2024January 13, 2025Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Steven E. Zeltmann, Chenyu Zhang, Zhaslan Baraissov, Yu-Tsun Shao | Summary: Precise alignment of the electron beam is critical for successful application of scanning transmission electron microscopes (STEM) to understanding materials at atomic level. Despite the success of aberration correctors, aberration correction is still […]

Emittance Minimization for Aberration Correction II: Physics-informed Bayesian Optimization of an Electron Microscope

Posted by dbos December 29, 2024January 13, 2025Cornell

Kavli Affiliate: David A. Muller | First 5 Authors: Desheng Ma, Steven E. Zeltmann, Chenyu Zhang, Zhaslan Baraissov, Yu-Tsun Shao | Summary: Aberration-corrected Scanning Transmission Electron Microscopy (STEM) has become an essential tool in understanding materials at the atomic scale. However, tuning the aberration corrector to produce a sub-{AA}ngstr"om probe is a complex and time-costly […]

The quantum Kibble-Zurek mechanism: the role of boundary conditions, endpoints and kink types

Posted by dbos December 28, 2024Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Jose Soto Garcia, Natalia Chepiga, , , | Summary: Quantum phase transitions are characterised by the universal scaling laws in the critical region surrounding the transitions. This universality is also manifested in the critical real-time dynamics through the quantum Kibble-Zurek mechanism. In recent experiments on a Rydberg […]

Direct Comparison of Magnetic Penetration Depth in Kagome Superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb)

Posted by dbos December 27, 2024January 13, 2025Cornell

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Austin Kaczmarek, Andrea Capa Salinas, Stephen D. Wilson, Katja C. Nowack, | Summary: We report measurements of the local temperature-dependent penetration depth, $lambda(T)$, in the Kagome superconductors AV$_3$Sb$_5$ (A = Cs, K, Rb) using scanning superconducting quantum interference device (SQUID) microscopy. Our results suggest that the […]

Measurement of the branching fraction, polarization, and time-dependent $CP$ asymmetry in $B^0 to ρ^+ρ^-$ decays and constraint on the CKM angle $φ_2$

Posted by dbos Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, I. Adachi, L. Aggarwal, H. Ahmed, N. Akopov | Summary: We present a measurement of the branching fraction and fraction of longitudinal polarization of $B^0 to rho^+ rho^-$ decays, which have two $pi^0$’s in the final state. We also measure time-dependent $CP$ violation parameters […]

Comprehensive Bayesian Exploration of Froggatt-Nielsen Mechanism

Posted by dbos December 27, 2024Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Satoshi Shirai, Keiichi Watanabe, , | Summary: The Froggatt-Nielsen (FN) mechanism successfully explains the hierarchical structure of fermion Yukawa couplings by introducing a U(1) flavor symmetry with distinct charge assignments for different fermion generations. While some FN charge assignments have been proposed, their evaluation has […]
