QFT, QED for condensed matter physics

[xmavidis]

I don't have the time now to study QFT in depth but I need some basic knowledge about QED and quantum forces (like casimir). I want to study the role of casimir force to solid state devices (photonic and plasmonic devices).

Which part of QFT is needed to study for now and which books are going to help me for this purpose?

I am an undergraduate (advanced courses taken: quantum mechanics, electrodynamics, statistical mechanics and solid state physics). I work on plasmonics and photonic crystals.

Can't you enroll in a QFT class or just sit in the lectures? You could try Gauge Theories in Particle Physics by Aitchison. That book is more elementary than the standard Peskin text in QFT. You might want to find text specifically for solid states physics though.

My suggestion is to just go the the library and search for QFT texts. There are bound to be some that fits your needs.

The study of QFT and QED is essential for understanding the behavior of particles and forces in condensed matter physics. In particular, the Casimir force, which arises from the quantum fluctuations of the electromagnetic field between two closely spaced objects, plays a crucial role in the behavior of solid state devices.

To begin studying QFT for condensed matter physics, I would recommend focusing on the basics of quantum field theory, such as the quantization of fields and Feynman diagrams. A good introductory book for this purpose is "Quantum Field Theory for the Gifted Amateur" by Tom Lancaster and Stephen J. Blundell.

To understand QED, I would suggest reading "Quantum Electrodynamics" by Richard Feynman. This classic text provides a clear and intuitive explanation of the theory, and also includes discussions on the Casimir force.

For a more in-depth understanding of the Casimir force in solid state devices, I would recommend "Casimir Physics" by V. M. Mostepanenko and N. N. Trunov. This book covers both theoretical and experimental aspects of the Casimir force, with a focus on its applications in condensed matter systems.

As an undergraduate, it is also important to continue building a strong foundation in quantum mechanics, electrodynamics, statistical mechanics, and solid state physics. These subjects are the building blocks for understanding QFT and QED, and will be essential for your future studies in plasmonics and photonic crystals.

Overall, studying QFT and QED for condensed matter physics can be a challenging but rewarding endeavor. I encourage you to continue your studies and seek guidance from your professors and colleagues as you delve into these fascinating topics. Best of luck in your research!
