Unveiling the Cosmic Dance of Conical Intersections: How they Shape the Laws of Physics

: A Glimpse into the Quantum Realm

Step into the mesmerizing world of quantum mechanics, where particles behave in astonishing ways that defy our everyday understanding of reality. Among the countless mind-boggling phenomena, one concept stands out as a pivotal junction of quantum physics known as "conical intersections". Get ready to embark on a captivating journey through space and time as we unravel the mysteries surrounding these extraordinary intersections.

Understanding Conical Intersections: The Meeting Point of Energy Landscapes

At the heart of conical intersections lies the fascinating encounter of two or more electronic potential energy surfaces. These surfaces represent the energy landscapes that describe the possible states of a molecule or a system. When two different electronic states approach each other, they can intersect at a conical shape, resembling the tip of a cone. This intricate geometric arrangement influences the behavior and properties of the system, giving rise to profound consequences.

The Duality of Conical Intersections: Where Reality Blurs

Conical intersections introduce a fascinating aspect of quantum mechanics – the duality of particles. According to quantum theory, particles exhibit both wave-like and particle-like characteristics. When a system encounters a conical intersection, this duality becomes particularly pronounced. The system's wave-like nature allows it to traverse multiple paths simultaneously, leading to fascinating phenomena such as interference. At the same time, the particle-like behavior gives rise to intriguing effects like non-adiabatic transitions, where the system quickly switches from one state to another.

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.
