Spatiotemporal chaos: the microscopic perspective
Nicolas Garnier, Daniel K Wójcik
Extended nonequilibrium systems can be studied in the framework of field theory or from dynamical systems perspective. Here we report numerical evidence that the sum of a well-defi…
Current source density reconstruction from incomplete data
Daniel K. Wojcik, Szymon Leski
We propose two ways of estimating the current source density (CSD) from measurements of voltage on a Cartesian grid with missing recording points using the inverse CSD method. The…
Classical and Quantum Fluctuation Theorems for Heat Exchange
Christopher Jarzynski, Daniel K. Wojcik
The statistics of heat exchange between two classical or quantum finite systems initially prepared at different temperatures are shown to obey a fluctuation theorem.
Crossover from Diffusive to Ballistic Transport in Periodic Quantum Maps
Daniel K. Wojcik, J. Robert Dorfman
We derive an expression for the mean square displacement of a particle whose motion is governed by a uniform, periodic, quantum multi-baker map. The expression is a function of bot…
Diffusive-ballistic crossover in 1D quantum walks
Daniel K. Wojcik, J. R. Dorfman
We show that particle transport in a uniform, quantum multi-baker map, is generically ballistic in the long time limit, for any fixed value of Planck's constant. However, for fixed…
Quantum Multibaker Maps: Extreme Quantum Regime
Daniel K. Wojcik, J. R. Dorfman
We introduce a family of models for quantum mechanical, one-dimensional random walks, called quantum multibaker maps (QMB). These are Weyl quantizations of the classical multibaker…
Fractality of certain quantum states
Daniel Wojcik, Karol Zyczkowski
We prove the theorem announced in Phys. Rev. Lett. {\bf 85}:5022, 2001 concerning the existence and properties of fractal states for the Schrödinger equation in the infinite one-di…
