Statistical  Mechanics

Fall 2023

Overview:

Motion of atoms/molecules in a gas. Classical statistics to describe thermal properties. Macroscopic properties of systems in a phenomenological manner (without being concerned about the microscopic properties). A system as a collection of large number of elementary particles. Connection between the bulk properties and the (statistical) behaviour of elementary particles using quantum mechanics.
