چکیده
We are concerned with a phase-space probability distribution which is known as Husimi $Q$-function of density operator respect to set coherent states $\vert\widetilde{\kappa}_{z,B,R,m}\rangle$ attached an $m$th hyperbolic Landau level and labeled by points $z$ open disk radius $R$, where $B>0$ proportional magnetic field strength. For representing projector on Fock state $\left\vert j\right\rangle$ we obtain the $Q_{j}$ discuss some its basic properties such characteristic function main statistical parameters. achieve same program for thermal (mixed states) isotonic oscillator establish lower bound associated thermodynamical potential. recover most results Euclidean setting (flat case) parameter $R$ goes infinity making appeal asymptotic formulas involving orthogonal polynomials special functions. As tool, summation formula Kamp\'{e} de F\'{e}riet $\digamma _{2:0:0}^{1:2:2}$.

Generalised Husimi Functions: Analyticity and Information Content
The analytic properties of a class of Generalised Husimi Functions are discussed, with particular reference to the problem of state reconstruction. The class consists of the subset of Wódkiewicz's operational probability distributions for which the filter reference state is a squeezed vacuum state. The fact that the function is analytic means that perfectly precise knowledge of its values over ...
متن کاملSemiclassical Husimi functions for spin systems
Rigorous derivation of semiclassical approximations in phase space via path integrals [1] for systems with one degree of freedom have recently received considerable attention, both for continuous variables and spin systems. Baranger et al [2], for example, have discussed the canonical coherent state path integral and its semiclassical approximation in some detail, including an initial-value rep...
متن کاملZero-field magnetic response functions in Landau levels.
We present a fresh perspective on the Landau level quantization rule; that is, by successively including zero-field magnetic response functions at zero temperature, such as zero-field magnetization and susceptibility, the Onsager's rule can be corrected order by order. Such a perspective is further reinterpreted as a quantization of the semiclassical electron density in solids. Our theory not o...
متن کاملON THE SHEARLET TRANSFORM USING HYPERBOLIC FUNCTIONS
In this paper, we focus on the study of shearlet transform which isdened by using the hyperbolic functions. As a result we check an admissibilitycondition such that implies the reconstruction formula. To this end, we will usethe concept of the classical shearlet, which indicates the position and directionof a singularity.
متن کاملINTERPOLATION BY HYPERBOLIC B-SPLINE FUNCTIONS
In this paper we present a new kind of B-splines, called hyperbolic B-splines generated over the space spanned by hyperbolic functions and we use it to interpolate an arbitrary function on a set of points. Numerical tests for illustrating hyperbolic B-spline are presented.
