Forced coupled oscillator wigner function
WebAug 31, 2012 · The starting point of the results presented here is a harmonic oscillator coupled to a reservoir, where the latter is a continuum of oscillators of all positive frequencies. The use of a continuum reservoir from the outset gives a much richer dynamical system compared to the use of a discrete reservoir. WebJun 21, 2024 · The Schrödinger equation in phase space is used to calculate the Wigner function for oscillator systems. The first is two oscillators including dissipative effects. In this case, the non-classicality of the states is studied by the non-classicality indicator of the Wigner function, which is calculated as a function of the dissipation parameter.

WebCoupled oscillators 1 Two masses To get to waves from oscillators, we have to start coupling them together. In the limit of a large number of coupled oscillators, we will find solutions while look like waves. Certain features of waves, such as resonance and normal modes, can be understood with a finite number of oscilla-tors.
