Analytic Model for the Energy Spectrum of the Anharmonic Oscillator
Michel Caffarel
In a recent work we have proposed an original analytic expression for the partition function of the quartic oscillator. This partition function, which has a simple and compact form…

Path integral for the quartic oscillator: An accurate analytic formula for the partition function
Michel Caffarel
In this work an approximate analytic expression for the quantum partition function of the quartic oscillator described by the potential is pre…
