A non-technical introduction to the renormalization of quantum field theories.

An overview of Noether's theorem

InterStellar Technologies is engaged in the research and development of technologies with applications to energy production and propulsion.

Several files in LaTeX format cover selected topics in Quantum Field Theory and Integrable Systems

Zero-point fluctuations in quantum fields give rise to observable forces between material bodies, the so-called Casimir forces.These lectures present the theory of the Casimir effect, primarily formulated in terms of Green's functions.

A simple introduction into the renormalization group (RG) in quantum field theory and an overview of the renormalization group method. The third section is devoted to essential topics of the renorm-group use in the QFT.

What is the Casimir Effect? From the Usenet FAQ.

These lectures present an elementary introduction to quantum gauge fields.

These postscript lectures deal with selected aspects of quantum field theory in curved spacetime

These notes review the effective lagrangian treatment of Goldstone and pseudo-Goldstone bosons, taking examples from high-energy/nuclear and condensed-matter physics.
