Density matrix of fermionic systems from coherent states via functional integrals
A complete system of states, closely related to the coherent states, and which incorporates the necessary algebra of fermion states, is used to derive an expression for the corresponding propagator via functional integrals. The calculation, based on a product expansion of the evolution operator, lea...

A complete system of states, closely related to the coherent states, and which incorporates the necessary algebra of fermion states, is used to derive an expression for the corresponding propagator via functional integrals. The calculation, based on a product expansion of the evolution operator, leads to an exact Feynman propagator from which the expectation value of the density matrix is obtained. © 1990. |
