Collisional and thermal ionization of sodium Rydberg atoms I. Experiment for nS and nD atoms with n=8-20
I. I. Ryabtsev, D. B. Tretyakov, I. I. Beterov +3
Collisional and thermal ionization of sodium nS and nD Rydberg atoms with n=8-20 has been studied. The experiments were performed using a two-step pulsed laser excitation in an eff…
Fokker-Planck equation for coupled anharmonic oscillators: symplectic integration and application to mean-field model of cooperative behavior
E. Klotins
Kinetics of systems specified by anharmonic, nonconservative and nonlocally coupled model Hamiltonians is reproduced in the Fokker-Planck and imaginary time Schrodinger equation te…
Reply to Comment on "Exact analytic solution for the generalized Lyapunov exponent of the 2-dimensional Anderson localization"
V. N. Kuzovkov, V. Kashcheyevs, W. von Niessen
We reply to comments by P.Marko, L.Schweitzer and M.Weyrauch [preceding paper] on our recent paper [J. Phys.: Condens. Matter 63, 13777 (2002)]. We demonstrate that our…
Coins Make Quantum Walks Faster
Andris Ambainis, Julia Kempe, Alexander Rivosh
We show how to search N items arranged on a grid in time , using a discrete time quantum walk. This result for the first time exhibits a…
A polynomial quantum query lower bound for the set equality problem
Gatis Midrijanis
The set equality problem is to tell whether two sets and are equal or disjoint under the promise that one of these is the case. This problem is related to the Graph Isomorp…
