openpathsampling.engines.toy.HarmonicOscillator

class openpathsampling.engines.toy.HarmonicOscillator(A, omega, x0)

Simple harmonic oscillator. Independent in each degree of freedom.

\(V(x) = \sum_i A_i * mass_i * omega_i^2 * (x_i - x0_i)^2\)

Parameters:

• A (list of float)

• omega (list of float)

• x0 (list of float)

__init__(A, omega, x0)
