**Title:**

Physics 798S: Superconductivity: An
introduction to the phenomenology and theory of superconductivity. This is a 3 credit course. There are three hours of lecture per week.

**Prerequisite:**

Graduate quantum mechanics. An undergraduate or (preferably) graduate
course in solid-state or condensed matter physics will also be helpful.

**Instructor:**

Prof.

**Required
Text:**

J. R. Waldram,
*Superconductivity of Metals and Cuprates*,

Other useful books are:

1)
M. Tinkham, *Introduction to
Superconductivity*, Second Edition, McGraw-Hill. This book is currently out of print, but will
be republished by

2)
Terry P. Orlando and Kevin A. Delin, *Foundations of Applied Superconductivity*,
Addison-Wesley,

See the class web site for a bibliography
of books on superconductivity.

**Homework:**

Homework will be assigned at least every
other week. It is imperative that you do
the homework and keep up with the material being covered in lecture. I may assign two students to write up
solutions to each of the homework assignments.
You may work together on the homework assignments, but what you submit
for grading should be in your own hand

**Class
Web Site**:

A class web site will announce all
homework assignments, and have general class information available. The web site can be found under “Physics
798S” at: http://www.physics.umd.edu/courses/Phys798S/anlage/index.html. Please check the web site periodically.

**Final
Grade:**

Based approximately on homework (~50%),
and semester paper on a topic in superconductivity (~50%). Active class and
office hour participation (i.e. asking questions!) will improve your chances of
obtaining a high letter grade.

**Tentative
Course Outline**:

1) Introduction – Basic
phenomena, perfect conductivity, perfect diamagnetism, critical temperature,
fields, and currents, type-I and type-II, high-temperature superconductors,
applications.

2) Simplest theory: perfect
conductivity, the

3) Microscopic theory: Second
quantization and BCS theory. Cooper
pairing instability, quasiparticles, the energy gap.

4) Ginzburg-Landau (GL) theory:
general Landau and GL theories, application to superconductors.

5) GL theory and type-II
superconductors (conventional and high-temperature.) Critical currents and fields, vortices, flux
flow, flux creep, the critical state model.

6) Fluctuation effects in low
and high-T_{c} superconductors: GL theory, Kosterlitz-Thouless
transition, scaling, vortex phase transitions.

7) Josephson effect:
Basic equations, shunted junction models, SQUIDs.

8) Electrodynamics, complex
conductivity, surface impedance.

9) Other topics, as time permits
(e.g. unconventional superconductivity, pseudogap in
high-T_{c} superconductors, etc.)
