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

Posted by dbos Cornell

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 Delft

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 Cornell

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 […]

Comprehensive Bayesian Exploration of Froggatt-Nielsen Mechanism

Posted by dbos Tokyo

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 […]

Gravitational Waves from Post-Collision of Fuzzy Dark Matter Solitons

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Chen Tan, Jing-Kang Bin, Ke Wang, , | Summary: According to the Schr"odinger-Poisson (SP) equations, fuzzy dark matter (FDM) can form a stable equilibrium configuration, the so-called FDM soliton. The SP system can also determine the evolution of FDM solitons, such as head-on collision. In this paper, […]
