Nonequilibrium thermodynamic analysis of squeezing
Abstract
We consider the thermodynamic properties of the squeezed vacuum state of a frequency-modulated quantum harmonic oscillator. We analytically relate the squeezing parameter to the irreversible work and the degree of nonadiabaticity of the frequency transformation. We furthermore determine the optimal modulation that leads to maximal squeezing, and discuss its implementation as well as the detection of squeezing in single cold ion traps.
