Note: On your HW write: “PHYS 416 HW, Grader Marius Radu” http://www.physics.purdue.edu/academic_programs/courses/phys416/ Instructor: Prof. Sergei Savikhin Office: PHYS 64 Office Hour: By appointment Telephone: 4943017 Email: [email protected] Grader: Marius Radu Office: PHYS 261 Office Hour: TBA Telephone: ? Email: [email protected] Syllabus on the course website: Today Stationary Quantum State (“state”) observables do not change Atom in a Box at www.daugerresearch.com Degeneracy = multiplicity # of states at the same energy Fundamental assumption of statistical mechanics: Ising model (Binary or twostate model) Multiplicity Function A closed system is equally likely to be in any accessible state Changing? Look at the table. Which properties are changing? Which are not changing? Changing Not Changing Statistical Mechanics  properties of many particles. Probabilities will matter. Statistical Physics How to connect the microscopic properties (lots of changes) to the macroscopic properties (not changing much) We will care about: N = # atoms T = temperature V = volume U = total energy Deep philosophical issue: Microscopic: physical laws are reversible in time Macroscopic: They’re not always reversible!...
