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 klaurent 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 […]

A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors

Posted by dbos Delft

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]
