Geometric Quantum mechanics -- Worked examples?

In summary, the conversation is about the geometric formulation of quantum mechanics as a Hamiltonian flow in a Kahler manifold and its application to concrete examples such as the Hydrogen atom, the harmonic oscillator, spin precession, and magnetic resonance. The speaker is looking for worked examples in this formalism and is recommended to look at a survey on coherent states by Zhang, Feng, and Gilmore.

I recently found that formulation of quantum mechanics as a hamiltonian flow in a Kahler manifold, where there is a classical hamiltonian, hamilton equations, poisson brackets and etc. And while the mathematics in terms of differential geometry is all fine and good, I'm having problem finding application of the formalism to concrete examples.

So does anyone know worked examples in stuff likes the Hydrogen atom, the harmonic oscillator, spin precession, magnetic resonance or stuff like that?, you know, the classical problems of QM but solved in the formalism of the geometric formulation?

There is a survey on coherent states by Zhang, Feng, and Gilmore that contains many examples, including their Kaehler description.

Gotcha. I will take a look at it
 

FAQ: Geometric Quantum mechanics -- Worked examples?

1. What is Geometric Quantum Mechanics?

Geometric Quantum Mechanics is a theoretical framework that combines the principles of quantum mechanics with the mathematical tools of differential geometry. It provides a geometric description of quantum systems and allows for the study of their properties and dynamics.

2. How is Geometric Quantum Mechanics different from traditional quantum mechanics?

In traditional quantum mechanics, the state of a quantum system is represented by a wave function in a complex vector space. In geometric quantum mechanics, the state is described by a point in a manifold, with the dynamics of the system governed by geometric structures such as curvature and connection.

3. What are some examples of applications of Geometric Quantum Mechanics?

Geometric Quantum Mechanics has been applied to various fields, including quantum computation, quantum information theory, and quantum field theory. It has also been used to study the properties of quantum systems in curved spacetime and to investigate the relationship between quantum mechanics and general relativity.

4. Can you provide a simple worked example of Geometric Quantum Mechanics?

One example is the study of a two-level quantum system, such as a spin-1/2 particle. In traditional quantum mechanics, the state of the particle is described by a wave function in a complex vector space. In geometric quantum mechanics, the state is represented by a point on a Bloch sphere, with the dynamics of the system described by the curvature of the sphere.

5. What are the advantages of using Geometric Quantum Mechanics?

One advantage is that it provides a more intuitive and geometric interpretation of quantum mechanics, making it easier to visualize and understand complex quantum systems. It also allows for the development of new mathematical tools and techniques for studying quantum systems, leading to potential advancements in quantum technology and research.
