there will also be occasional Friday classes, usually to review homeworks.

This robust form of carbon (C60) remains intact when cooled into a crystal.

This nice molecule (Mo8C12) only exists in gas phase. It reacts to make other compounds in condensed phases

Tat-Sang Choy's Fermi surface
data base; periodic table of the
Fermi surfaces.

This Penrose tile is a 2-D example of a quasicrystal.  There is perfect long-range order and no periodicity in the normal sense.


Bulletin Description: This course concentrates on the basic notions of solid state physics, treated mostly within the single-particle approximation. Main topics include: crystal lattices and symmetries, reciprocal lattice and state counting, phonons, electron energy band theory, bonding and cohesion (semi-quantitatively), electron dynamics and electron transport in metals and semiconductors, screening, optical properties of solids, and an introduction to magnetism. Additional topics not mentioned in the bulletin description: superconductivity, a little nanophysics, and a tiny bit of surface physics.

Prerequisite:  It is assumed that students are familiar with quantum mechanics at the level of one semester of graduate quantum mechanics, or passage of the qualifying exam part I in physics, or a graduate level course in physical chemistry.  Similar knowledge of statistical mechanics and electromagnetism is expected.  A prior course in solid state physics is NOT a prerequisite, but students who have never studied this subject before should please buy a copy of Kittel's book "Introduction to Solid State Physics" and read the chapters in this book while PHY 555 covers the corresponding material at a more advanced level.

Syllabus for Fall 2003

I. Aims of the course:

II. Procedures and Requirements: There will be homework problems assigned (10 problem sets over the semester.)

III. Grading:

IV Required text: John M. Ziman, Principles of the Theory of Solids, Cambridge University Press, 2nd edition, 1979 paperback.

V. Academic Honesty:  Discussions with fellow students are strongly encouraged, but work which is submitted for grading must be in your own words.  You should review the definition of plagiarism.

VI.Americans with Disabilities Act: If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, ECC (Educational Communications Center) Building, room 128, (631) 632-6748.  They will determine with you what accommodations are necessary and appropriate. All information and documentation is confidential.
