Undergrad How do you derive Slater determinant from creation operator?

Click For Summary
To derive the Slater determinant for N fermions, one can start with the vacuum state and utilize creation operators that adhere to anticommutation relations. A recommended resource for this proof is Gordon Baym's book, "Lectures on Quantum Mechanics," particularly the chapter on Second Quantization, which provides a solid explanation despite minor typographical errors. The connection between the structures of the vacuum state and the Slater determinant is emphasized, highlighting their similarities. Engaging with this material can clarify the rigorous derivation process. Understanding these concepts is essential for grasping the behavior of fermionic systems in quantum mechanics.

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.
 
Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
