A ug 1 99 5 Crossover of a nonequilibrium system studied by coherent anomaly method
نویسنده
چکیده
In the stochastic cellular automaton of rule 18 defined by S. Wolfram [Rev. Mod. Phys. 55, 601 (1983)] the crossover of the critical behaviour induced by nonlocal site exchange was investigated using the coherent anomaly method. The continuous variation of the critical β exponent was confirmed. 64.60.Fr, 05.40.+j Typeset using REVTEX

We have constructed the coherent state of U(N, 1) , which is an extension of the Barut-Girardello (BG) coherent state of SU(1, 1), in our previous paper. However there is a restriction that the eigenvalue of the Casimir operator is natural number. In this paper we construct the coherent state in the analytic representation to overcome this restriction. Next we show that the measure of the BG co...
متن کاملTuned transition from quantum to classical for macroscopic quantum states.
The boundary between the classical and quantum worlds has been intensely studied. It remains fascinating to explore how far the quantum concept can reach with use of specially fabricated elements. Here we employ a tunable flux qubit with basis states having persistent currents of 1 μA carried by a million pairs of electrons. By tuning the tunnel barrier between these states we see a crossover ...

Coherent resonance is the effect of resonant excitation of nonlinear coherent modes in trapped Bose condensates. This novel effect is shown to be feasible for Bose-condensed trapped gases. Conditions for realizing this effect are derived. A method of stabilizing Bose condensates with attractive interactions is advanced. The origin of dynamic critical phenomena is elucidated. Interference effect...
متن کاملCurrent characteristics of the single-electron transistor at the degeneracy point
The linear and nonlinear transport properties of the single-electron transistor at the degeneracy point are investigated for the case of weak single-mode tunnel junctions. Two opposing scenarios are considered, distinguished by whether or not electrons can propagate coherently between the two tunnel junctions. Each of these two scenarios corresponds to the realization of a different multichanne...

A novel realization is provided for the scattering states of the N -particle Calogero-Moser Hamiltonian. They are explicitly shown to be the coherent states of the singular oscillators of the Calogero-Sutherland model. Our algebraic treatment is straightforwardly extendable to a large number of few and many-body interacting systems in one and higher dimensions. PACS: 03.65.-w, 03.65.Ge Typeset ...
