WebTopology and Chirality Claudia Felser Max Planck Institute Chemical Physics of Solids, Dresden, Germany Email: [email protected] Abstract Topology, a mathematical concept, recently became a hot and truly transdisciplinary topic in condensed matter physics, solid state chemistry and materials science. All 200 000 inorganic WebJun 5, 2012 · Summary. Stereochemistry is the study of the three-dimensional structure of molecules, and topology is the study of those properties of geometric objects that are invariant under continuous transformations. It is not obvious that these two fields have anything in common. In fact, not long ago there was little communication between …

WebJul 31, 2000 · The applications of topological techniques for understanding molecular structures have become increasingly important over the past thirty years. In this topology text, the reader will learn about knot theory, 3-dimensional manifolds, and the topology of embedded graphs, while learning the role these play in understanding molecular structures. WebMay 12, 2024 · Topology, a well-established concept in mathematics, has nowadays become essential to describe condensed matter. At its core are chiral electron states on the bulk, surfaces and edges of the condensed matter systems, in which spin and momentum of the electrons are locked parallel or anti-parallel to each other. Magnetic and non …
WebApr 8, 2024 · We also show that spherical topology necessitates regions of the material with the “wrong” handedness—if the material is naturally right handed, some parts are nonetheless left handed—which represent a novel localized chiral structure. Our work provides a new framework for analyzing chiral materials and their defects. WebWhen Topology Meets Chemistry: A Topological Look At Molecular Chirality is a book in chemical graph theory on the graph-theoretic analysis of chirality in molecular structures. It was written by Erica Flapan, based on a series of lectures she gave in 1996 at the Institut Henri Poincaré, and was published in 2000 by the Cambridge University Press and …
