The path integral technique is used to derive a possible expression for the density operator of the fermionic harmonic oscillator. In terms of the Grassmann variables, the fermionic density operator can be written as: 𝜌 𝐹 (𝛽) = 𝑐 βˆ— (𝛽)𝑐(𝛽) Β± 𝑐 βˆ— (𝛽)𝑐(𝛽) 𝑒 βˆ’π›½πœ” , where +(βˆ’) means that the sum over all antiperiodic (periodic) orbits. Our density operator is then used to obtain the usual fermionic partition function which describes the fermionic oscillator in thermal equilibrium. Also…

The practical specializations for quantum free and harmonic motions, along with the smearing justification for the Bohr’s quantum stability postulate, advocate for the reliability of assuming PI formalism of quantum mechanics as a versatile one, suited for analytically and/or computationally modeling of a variety of fundamental physical and chemical reactivity concepts characterizing the many-electronic systems.
