Abstract
Within the framework of the discipline "Quantum mechanics for mathematicians", it is planned to present, in particular, the following topics in a form accessible to mathematics students: the algebra of observables in classical mechanics, states in classical statistical mechanics, physical bases of quantum mechanics, states in quantum mechanics, the Schrödinger equation, the Heisenberg commutation relations, coordinate and momentum representations, the interconnection between quantum and classical mechanics, the harmonic oscillator, the hydrogen atom, scattering of a one-dimensional particle by a potential barrier. Knowledge of classical mechanics is welcome.
Learning Objectives
- Formation and generalization of knowledge on quantum mechanics at the level of fundamental physical theory; mastering the mathematical apparatus of quantum mechanics; formation of the ability to apply theoretical knowledge in solving problems of quantum mechanics; the development of physical thinking; mastery of theoretical methods of cognition.
Expected Learning Outcomes
- To have a concept of the algebra of observables and states in classical mechanics. To know Liouville’s theorem, and two pictures of motion in classical mechanics. To understand the physical bases of quantum mechanics.
- To have a concept of the observables and states in quantum mechanics. To know Heisenberg uncertainty relations. Physical meaning of the eigenvalues and eigenvectors of observables. To understand two pictures of motion in quantum mechanics. To be able to write and solve Schrödinger equation. To be able to find stationary states.
