Lecture Notes in Physics,0075-8450 ;9653-030-34881-4 Introduction -- Theory of Adiabatic Evolution -- Conical Intersections in Molecular Physics -- Conical Intersections in Condensed Matter Physics -- Conical Intersections in Cold Atom Physics -- Conical Intersections in Other Physical Systems.This concise book introduces and discusses the basic theory of conical intersections with applications in atomic, molecular and condensed matter physics. Conical intersections are linked to the energy of quantum systems. They can occur in any physical system characterized by both slow and fast degrees of freedom - such as e.g. the fast electrons and slow nuclei of a vibrating and rotating molecule - and are important when studying the evolution of quantum systems controlled by classical parameters. Furthermore, they play a relevant role for understanding the topological properties of condensed matter systems. Conical intersections are associated with many interesting features, such as a breakdown of the Born-Oppenheimer approximation and the appearance of nontrivial artificial gauge structures, similar to the Aharonov-Bohm effect. Some applications presented in this book include - Molecular Systems: some molecules in nonlinear nuclear configurations undergo Jahn-Teller distortions under which the molecule lower their symmetry if the electronic states belong to a degenerate irreducible representation of the molecular point group. - Solid State Physics: different types of Berry phases associated with conical intersections can be used to detect topologically nontrivial states of matter, such as topological insulators, Weyl semi-metals, as well as Majorana fermions in superconductors. - Cold Atoms: the motion of cold atoms in slowly varying inhomogeneous laser fields is governed by artificial gauge fields that arise when averaging over the fast internal degrees of freedom of the atoms. These gauge fields can be Abelian or non-Abelian, which opens up the possibility to create analogs to various relativistic effects at low speed.Lecture Notes in Physics,0075-8450 ;965Quantum physicsSolid state physicsQuantum opticsChemistry, Physical and theoreticalQuantum Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P19080Solid State Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25013Quantum Opticshttps://scigraph.springernature.com/ontologies/product-market-codes/P24050Theoretical and Computational Chemistryhttps://scigraph.springernature.com/ontologies/product-market-codes/C25007Quantum physics.Solid state physics.Quantum optics.Chemistry, Physical and theoretical.Quantum Physics.Solid State Physics.Quantum Optics.Theoretical and Computational Chemistry.530.1435530.1435Larson Jonasauthttp://id.loc.gov/vocabulary/relators/aut890813Sjöqvist Erikauthttp://id.loc.gov/vocabulary/relators/autÖhberg Patrikauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910373955703321Conical Intersections in Physics1989907UNINA
