| Abstract: | We shown that the Hamiltonian of the harmonic oscillator with time-dependent frequency and boundary conditions is related to the effective Harmiltonian of a particle in an infinite potential well with a moving wall by a time-dependent gauge transformation. Furthermore, we calculated the non-adiabatic Berry phase of wave function of the harmonic oscillator with time-dependent frequency and boundary conditions by using the geometric concepts such as the geometric distance and geometric length of the curve. |
