چکیده

Relations between classical phase-space distributions and Wigner functions for multiparticle production processes. Abstract The effects of interpreting classical phase space distributions as Wigner functions, which is common in models of multiparticle production , are discussed. The temperature for the classical description is always higher than that for its Wigner function interpretation. A rough estimate shows that the corresponding correction is proportional to R −2 , where R is the radius of the interaction region, and that it is negligible for heavy ion scattering, but at the few percent level for e + e − annihilations.

The Adler sum rule states that the integral over energy of a difference of neutrino-nucleon and antineutrino-nucleon structure functions is a constant, independent of the four-momentum transfer squared. This constancy is a consequence of the local commutation relations of the time components of the hadronic weak current, which follow from the underlying quark structure of the standard model.

The quantum state of a system of n qubits can be represented by a Wigner function on a discrete phase space, each axis of the phase space taking values in the finite field F 2 n. Within this framework, we show that one can make sense of the notion of a " rotationally invariant state " of any collection of qubits, and that any such state is, in a well defined sense, a state of minimum uncertainty.

We present a systematic semiclassical procedure to compute the partition function for scalar field theories at finite temperature. The central objects in our scheme are the solutions of the classical equations of motion in imaginary time, with spatially independent boundary conditions. Field fluctuations – both field deviations around these classical solutions, and fluctuations of the boundary ...
