How do you derive Slater determinant from creation operator?

Click For Summary
SUMMARY

The derivation of the Slater determinant for N fermions can be achieved by starting with the vacuum state and employing creation operators that adhere to anticommutation relations. Gordon Baym's book, Lectures on Quantum Mechanics, provides a comprehensive explanation in the chapter dedicated to Second Quantization, although it contains minor typographical errors regarding the factor of ## \sqrt{n!} ##. This foundational concept is essential for understanding the behavior of fermionic systems in quantum mechanics.

PREREQUISITES
  • Understanding of vacuum states in quantum mechanics
  • Familiarity with creation and annihilation operators
  • Knowledge of anticommutation relations
  • Basic concepts of Slater determinants
NEXT STEPS
  • Study Gordon Baym's Lectures on Quantum Mechanics focusing on Second Quantization
  • Research the mathematical properties of Slater determinants in fermionic systems
  • Explore advanced topics in quantum mechanics related to fermions and bosons
  • Learn about the implications of anticommutation relations in quantum field theory
USEFUL FOR

Quantum physicists, graduate students in physics, and anyone studying the mathematical foundations of fermionic systems will benefit from this discussion.

Hello,

Could someone provide me with a good proof or explain me here how we can derive Slater determinant for N fermions by starting with the vacuum state and the creation operators with anticommutation equations. I see that the idea of both these structures is similar but I cannot work it out rigorously.

Thank you.

Gordon Baym's book Lectures on Quantum Mechanics covers this in the chapter on Second Quantization. His treatment of it is quite good, other than on occasion he does have a ## \sqrt{n!} ## that should be simply a ## \sqrt{n} ## or similar minor typo. I think the book is currently out of print but very good reading if you can get a copy of it.
 
Thank you, I will take a look at this chapter.
