Title: Uncertainty principle for Gabor systems and the Zak transform

Abstract

We show that if g(set-membership sign)L{sup 2}(R) is a generator of a Gabor orthonormal basis with the lattice ZxZ, then its Zak transform Z(g) satisfies {nabla}Z(g)(negated-set-membership sign)L{sup 2}([0,1){sup 2}). This is a generalization and extension of the Balian-Low uncertainty principle.

  • Time-divergence in linear and nonlinear classical response functions can be removed by taking a phase-space average within the quantized uncertainty volume O(({Dirac_h}/2{pi}){sup n}) around the microcanonical energy surface. For a quasiperiodic system, the replacement of the microcanonical distribution density in the classical response function with the quantized uniform distribution density results in agreement of quantum and classical expressions through Heisenberg's correspondence principle: each matrix element <u|{alpha}(t)|v> corresponds to the (u-v)th Fourier component of {alpha}(t) evaluated along the classical trajectory with mean action (J{sub u}+J{sub v})/2. Numerical calculations for one- and two-dimensional systems show good agreement between quantum and classical results.more » The generalization to the case of N degrees of freedom is made. Thus, phase-space averaging within the quantized uncertainty volume provides a useful way to establish the classical-quantum correspondence for the linear and nonlinear response functions of a quasiperiodic system.« less
  • A method of calculation of electromagnetic transients in a multiconductor transmission systems using the superposition principle and Hartley transform is developed in the paper. The method takes into account all frequency dependent parameters of the transmission system. In the method, the impulse response of a transmission system are first obtained in the actual phase domain using a Hartley transform method. Then, the impulse responses are included in a transient calculation using the superposition principle. Up to now, Hartley transform has not been used in this field. Therefore, the properties and advantages of the transform are considered in comparison with moremore » usual approaches using the other transform methods. The new method is applied on different transmission systems (underground cables and overhead lines). The obtained results are compared with those calculated by using conventional methods and field tests. The accuracy of the method is found to be good. The method, therefore, can be used as a very efficient alternative to the existing approximate models implemented in the programs of the time domain when all frequency dependent parameters have to be taken into account.« less
  • Even though mutually unbiased bases and entropic uncertainty relations play an important role in quantum cryptographic protocols, they remain ill understood. Here, we construct special sets of up to 2n+1 mutually unbiased bases (MUBs) in dimension d=2{sup n}, which have particularly beautiful symmetry properties derived from the Clifford algebra. More precisely, we show that there exists a unitary transformation that cyclically permutes such bases. This unitary can be understood as a generalization of the Fourier transform, which exchanges two MUBs, to multiple complementary aspects. We proceed to prove a lower bound for min-entropic entropic uncertainty relations for any set ofmore » MUBs and show that symmetry plays a central role in obtaining tight bounds. For example, we obtain for the first time a tight bound for four MUBs in dimension d=4, which is attained by an eigenstate of our complementarity transform. Finally, we discuss the relation to other symmetries obtained by transformations in discrete phase space and note that the extrema of discrete Wigner functions are directly related to min-entropic uncertainty relations for MUBs.« less
