Edge modes and boundary impurities in the anisotropic Heisenberg spin chain
Pradip Kattel, Parameshwar R. Pasnoori, J. H. Pixley +1
We present a comprehensive analysis of boundary phenomena in a spin- anisotropic Heisenberg chain (XXZ-) in the gapped antiferromagnetic phase, with a par…
Compatibility of Quantum Measurements and the Emergence of Classical Objectivity
Emery Doucet, Sebastian Deffner
The study of measurements in quantum mechanics exposes many of the ways in which the quantum world is different. For example, one of the hallmarks of quantum mechanics is that obse…
Euclid preparation: Determining the weak lensing mass accuracy and precision for galaxy clusters
Euclid Collaboration, L. Ingoglia, M. Sereno +279
We investigate the level of accuracy and precision of cluster weak-lensing (WL) masses measured with the \Euclid data processing pipeline. We use the DEMNUni-Cov -body simulatio…
Ultrabroadband Coherent Perfect Absorption with Composite Graphene Metasurfaces
Wei Zou, Tianjing Guo, Christos Argyropoulos
We investigate the design and performance of a new multilayer graphene metasurface for achieving ultrabroadband coherent perfect absorption (CPA) in the THz regime. The proposed st…
Classifying two-body Hamiltonians for Quantum Darwinism
Emery Doucet, Sebastian Deffner
Quantum Darwinism is a paradigm to understand how classically objective reality emerges from within a fundamentally quantum universe. Despite the growing attention that this field…
Toward a 2D Local Implementation of Quantum LDPC Codes
Noah Berthusen, Dhruv Devulapalli, Eddie Schoute +4
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes which affects code performance and ease of physical realizati…
