Path integral derivation of Bloch-Redfield equations for a qubit weakly coupled to a heat bath: Application to nonadiabatic transitions
Nicholas Wynn Watkins, David Waxman
Quantum information processing has greatly increased interest in the phenomenon of environmentally-induced decoherence. The spin boson model is widely used to study the interaction…
Scaling and Commonality in Anomalous Fluctuation Statistics in Models for Turbulence and Ferromagnetism
S. C. Chapman, G. Rowlands, N. W. Watkins
Recently, Portelli et al (2003) have semi-numerically obtained a functional form of the probability distribution of fluctuations in the total energy flow in a model for fluid turbu…
The application of computational mechanics to the analysis of geomagnetic data
Richard W. Clarke, Mervyn P. Freeman, Nicholas W. Watkins
We discuss how the ideal formalism of Computational Mechanics can be adapted to apply to a non-infinite series of corrupted and correlated data, that is typical of most observed na…
The relationship between extremum statistics and universal fluctuations
Sandra Chapman, George Rowlands, Nicholas Watkins
The normalized probability density function (PDF) of global measures of a large class of highly correlated systems has previously been demonstrated to fall on a single non-Gaussian…
Signatures of dual scaling regimes in a simple avalanche model for magnetospheric activity
S. C. Chapman, N. W. Watkins, G. Rowlands
Recently, the paradigm that the dynamic magnetosphere displays sandpile-type phenomenology has been advanced, in which energy dissipation is by means of avalanches which do not hav…
