A simple closed formula is proposed for the short-time density matrix of a one-dimensional anharmonic oscihator in thermal equilibrium. The formula can be used in an iterative numerical calculation of the equilibrium density matrix at a given temperature starting from the density matrix at a higher
A thorough analysis on the integrability of the anharmonic oscillator with variable damping coefficients is carried out. Using PainlevΓ© analysis we find the most general form of the damping that allows for integrability of the oscillator. We present a novel method that yields exact and explicit solu
