Decoherence models for discrete-time quantum walks and their application to neutral atom experiments [PDF]

open access: yesNew Journal of Physics, 2014
We discuss decoherence in discrete-time quantum walks in terms of a phenomenological model that distinguishes spin and spatial decoherence. We identify the dominating mechanisms that affect quantum-walk experiments realized with neutral atoms walking in ...

New formulation of discrete Wigner-Ville distribution

open access: closedElectronics Letters, 1991
A new formulation of the discrete Wigner-Ville distribution is presented which can be implemented directly using standard fast Fourier transform techniques. For a non-negative frequency resolution of N points, only an N point FFT is needed.

Microcanonical Rate Constants With Rice-Ramsperger-Kassel-Marcus in Eyringpy. [PDF]

open access: yesJ Comput Chem
The new implementation of the Rice‐Ramsperger‐Kassel‐Marcus theory in Eyringpy accurately calculates both the density of states (DOS) for reactants and transition states, as well as the microcanonical rate constants kE$$ k(E) $$ for unimolecular chemical reactions, incorporating tunneling corrections using the Eckart model.

Probability Representation of Quantum States

open access: yesEntropy, 2021
The review of new formulation of conventional quantum mechanics where the quantum states are identified with probability distributions is presented. The invertible map of density operators and wave functions onto the probability distributions describing ...

Quantum eigenstates from classical Gibbs distributions

open access: yesSciPost Physics, 2021
We discuss how the language of wave functions (state vectors) and associated non-commuting Hermitian operators naturally emerges from classical mechanics by applying the inverse Wigner-Weyl transform to the phase space probability distribution and ...

Distribution of the delay time and the dwell time for wave reflection from a long random potential [PDF]

open access: yes, 2001
We re-examine and correct an earlier derivation of the distribution of the Wigner phase delay time for wave reflection from a long one-dimensional disordered conductor treated in the continuum limit.

Spectra of phase point operators in odd prime dimensions and the extended Clifford group [PDF]

open access: yes, 2007
We analyse the role of the Extended Clifford group in classifying the spectra of phase point operators within the framework laid out by Gibbons et al for setting up Wigner distributions on discrete phase spaces based on finite fields.
