Both stochastic and deterministic methods have been applied to solve the one-dimensional Wigner equation. However, only the Wigner Monte Carlo method, using the signed-particle technique [1], has made multi-dimensional Wigner simulations viable thus far [2]; a multidimensional approach is essential for the simulation of realistic semiconductor devices. The primary challenge lies in the fact tha...
The Wigner function shares several properties with classical distribution functions on phase space, but is not positive-definite. The integral of the Wigner function over a given region of phase space can therefore lie outside the interval [0, 1]. The problem of finding bestpossible upper and lower bounds for a given region is the problem of finding the greatest and least eigenvalues of an asso...
An analogue of the Livernet–Loday operad for two compatible brackets, which is a flat deformation of the bi-Hamiltonian operad is constructed. The Livernet–Loday operad can be used to define ⋆-products and deformation quantization for Poisson structures. The constructed operad is used in the same way, introducing a definition of operadic deformation quantization of compatible Poisson structures...
We give an explicit construction of a deformation quantization of the algebra of functions on a Poisson manifolds, based on Kontsevich’s local formula. The deformed algebra of functions is realized as the algebra of horizontal sections of a vector bundle with flat connection.
