Spin-Orbit Torques in Transition Metal Dichalcogenide/Ferromagnet Heterostructures
Jan Hidding, Marcos H. D. Guimarães
In recent years, there has been a growing interest in spin-orbit torques (SOTs) for manipulating the magnetization in nonvolatile magnetic memory devices. SOTs rely on the spin-orb…
The role of device asymmetries and Schottky barriers on the helicity-dependent photoresponse of 2D phototransistors
Jorge Quereda, Jan Hidding, Talieh S. Ghiasi +3
Circular photocurrents (CPC), namely circular photogalvanic (CPGE) and photon drag effects, have recently been reported both in monolayer and multilayer transition metal dichalcoge…
The cosmic spiderweb: equivalence of cosmic, architectural, and origami tessellations
Mark C. Neyrinck, Johan Hidding, Marina Konstantatou +1
For over twenty years, the term 'cosmic web' has guided our understanding of the large-scale arrangement of matter in the cosmos, accurately evoking the concept of a network of gal…
Caustic Skeleton & Cosmic Web
Job Feldbrugge, Rien van de Weygaert, Johan Hidding +1
We present a general formalism for identifying the caustic structure of an evolving mass distribution in an arbitrary dimensional space. For the class of Hamiltonian fluids the ide…
The Zeldovich & Adhesion approximations, and applications to the local universe
Johan Hidding, Rien van de Weygaert, Sergei Shandarin
The Zeldovich approximation (ZA) predicts the formation of a web of singularities. While these singularities may only exist in the most formal interpretation of the ZA, they provid…
Statistics of Caustics in Large-Scale Structure Formation
Job Feldbrugge, Johan Hidding, Rien van de Weygaert
The cosmic web is a complex spatial pattern of walls, filaments, cluster nodes and underdense void regions. It emerged through gravitational amplification from the Gaussian primord…
The Zeldovich approximation: key to understanding Cosmic Web complexity
Johan Hidding, Sergei F. Shandarin, Rien van de Weygaert
We describe how the dynamics of cosmic structure formation defines the intricate geometric structure of the spine of the cosmic web. The Zeldovich approximation is used to model th…
Betti numbers of Gaussian fields
Changbom Park, Pratyush Pranav, Pravabati Chingangbam +6
We present the relation between the genus in cosmology and the Betti numbers for excursion sets of three- and two-dimensional smooth Gaussian random fields, and numerically investi…
Alpha, Betti and the Megaparsec Universe: on the Topology of the Cosmic Web
Rien van de Weygaert, Gert Vegter, Herbert Edelsbrunner +13
We study the topology of the Megaparsec Cosmic Web in terms of the scale-dependent Betti numbers, which formalize the topological information content of the cosmic mass distributio…
Adhesion and the Geometry of the Cosmic Web
Johan Hidding, Rien van de Weygaert, Gert Vegter +1
We present a new way to formulate the geometry of the Cosmic Web in terms of Lagrangian space. The Adhesion model has an ingenious geometric interpretation out of which the spine o…
The Sticky Geometry of the Cosmic Web
Johan Hidding, Rien van de Weygaert, Gert Vegter +2
In this video we highlight the application of Computational Geometry to our understanding of the formation and dynamics of the Cosmic Web. The emergence of this intricate and perva…
Probing Dark Energy with Alpha Shapes and Betti Numbers
Rien van de Weygaert, Pratyush Pranav, Bernard J. T. Jones +8
We introduce a new descriptor of the weblike pattern in the distribution of galaxies and matter: the scale dependent Betti numbers which formalize the topological information conte…
The Cosmically Depressed: Life, Sociology and Identity of Voids
Rien van de Weygaert, Erwin Platen, Esra Tigrak +5
We review and discuss aspects of Cosmic Voids that form the background for our Void Galaxy Survey (see accompanying paper by Stanonik et al.). Following a sketch of the general cha…
