Wigner function for damped systems
Both classical and quantum damped systems give rise to complex spectra and corresponding resonant states. We investigate how resonant states, which do not belong to the Hilbert space, fit the phase space formulation of quantum mechanics. It turns out that one may construct out of a pair of resonant states an analog of the stationary Wigner function.
متن کاملWigner Function and Decoherence
I briefly review the role of the Wigner function in the study of the quantum-to-classical transition through interaction with the environment (decoherence). My contribution to the Fifth Wigner Symposium in Vienna touches upon two of Wigner’s fields of interest: His work on the interpretation of quantum theory [1] and his discussion of quasi-probability functions as encoded in the famous Wigner ...
متن کاملWigner function for nonparaxial wave fields.
The generalized optical transfer function and the spectral correlation function are investigated for nonparaxial two-dimensional wave fields. The angle-impact marginal of the four-dimensional Wigner function is derived directly. For focused wave fields of semiangle greater than 90 degrees, the spectral correlation function exhibits overlapping and interference. For focused wave fields for which...
متن کاملWigner function for a driven anharmonic oscillator
We consider the quantum model of a driven anharmonic oscillator, in the presence of dissipation, and present an exact analytic solution for the corresponding Wigner function in the steady-state regime. This provides explicit phase-space images of the resulting state of the cavity mode, and allows us to understand how the quantum interference is built up into it. The photon number probability di...
متن کاملWigner function and ambiguity function for non-paraxial wavefields
The connection between the Wigner function and the generalized OTF, and between the ambiguity function and the generalized OTF is investigated for non-paraxial scalar wavefields. The treatment is based on two-dimensional (2-D) wavefields for simplicity, but can be extended to the three-dimensional case.
