Coherent-state path integral calculation of the Wigner function
We consider a set of operators x̂ = (x̂1, . . . , x̂N ) with diagonal representatives P (n) in the space of generalized coherent states |n〉 : x̂ = ∫ dμ(n)P (n)|n〉〈n|. We regularize the coherent-state path integral as a limit of a sequence of averages 〈 〉L over polygonal paths with L vertices n1...L. The distribution of the path centroid P̄ = 1 L ∑L l=1 P (nl) tends to the Wigner function W (x), the ...
متن کاملPath-integral calculation of the two-dimensional He phase diagram
Path-integral Monte Carlo simulations have been used to determine the phase diagram of a two-dimensional He film in a range of temperatures and coverages where it undergoes solidification, superfluidity, and a liquid-gas transition (0.25 K<T<1.5 K 0,s,0.094 Å). We determine the phase-transition densities and give the coefficients for a functional form of the free energy in the liquid, solid, an...
متن کاملPhase Space Path Integral for the Dirac Equation
A c-number path integral representation is constructed for the solution of the Dirac equation. The integration is over the real trajectories in the continuous three-space and other two canonical pairs of compact variables controlling the dynamics of the spin and the chirality flips. The problems to overcome in order to find a c-number path integral representation for the solution of the Dirac e...
متن کاملWigner function for discrete phase space: exorcising ghost images
We construct, using simple geometrical arguments, a Wigner function defined on a discrete phase space of arbitrary integer Hilbert-space dimension that is free of redundancies. “Ghost images” plaguing other Wigner functions for discrete phase spaces are thus revealed as artifacts. It allows to devise a corresponding phase-space propagator in an unambiguous manner. We apply our definitions to ei...
متن کاملPath Integral Quantization for a Toroidal Phase Space
A Wiener-regularized path integral is presented as an alternative way to formulate Berezin-Toeplitz quantization on a toroidal phase space. Essential to the result is that this quantization prescription for the torus can be constructed as an induced representation from anti-Wick quantization on its covering space, the plane. When this construction is expressed in the form of a Wiener-regularize...
