چکیده
Motivated by the existence of bi-Hamiltonian classical systems and the correspondence principle, in this paper we analyze the problem of finding Hermitian scalar products which turn a given flow on a Hilbert space into a unitary one. We show how different invariant Hermitian scalar products give rise to different descriptions of a quantum system in the Ehrenfest and Heisenberg picture.

Proposed Observations of Gravity Waves from the Early Universe via " Millikan Oil Drops " Received Day Month Year Revised Day Month Year Communicated by Managing Editor
Pairs of Planck-mass drops of superfluid helium coated by electrons (i.e., “Millikan oil drops”), when levitated in a superconducting magnetic trap, can be efficient quantum transducers between electromagnetic (EM) and gravitational (GR) radiation. This leads to the possibility of a Hertz-like experiment, in which EM waves are converted at the source into GR waves, and then back-converted at th...
متن کاملDiscrete Coherent States for N Qubits
Received Day Month Year Revised Day Month Year Discrete coherent states for a system of n qubits are introduced in terms of eigenstates of the finite Fourier transform. The properties of these states are pictured in phase space by resorting to the discrete Wigner function.

متن کاملPolynomial functions are re nable
Received (Day Month Year) Revised (Day Month Year) Communicated by (xxxxxxxxxx) The scope of renable functions in wavelet theory is focused to localized functions. In our paper we like to widen that scope, in particular we show that all polynomial functions are renable. This may yield an interesting notion of convolution of polynomials.
متن کاملAnalysis of Pulse Propagation Through an One-Dimensional Random Medium Using Complex Martingales
Received (Day Month Year) Revised (Day Month Year) We show that the propagation of pulses in an one-dimensional random medium can be characterized using a new complex martingale representation of the transmission coefficient. This representation holds in the frequency domain and in a certain asymptotic limit where diffusion approximations can be used.
