Gaussian white noise as a resource for microscopic engines
Andreas Dechant, Adrian Baule, Shin-ichi Sasa
We show that uncorrelated Gaussian noise, despite its paradigmatic association with thermal equilibrium, can drive a system out of equilibrium and can serve as a resource from whic…
Heavy-tailed phase-space distributions beyond Boltzmann-Gibbs and equipartition: Statistics of confined cold atoms
Andreas Dechant, Shalom Tzvi Shafier, David A. Kessler +1
The Boltzmann-Gibbs density, a central result of equilibrium statistical mechanics, relates the energy of a system in contact with a thermal bath to its equilibrium statistics. Thi…
Aging Wiener-Khinchin Theorem and Critical Exponents of Noise
N. Leibovich, A. Dechant, E. Lutz +1
The power spectrum of a stationary process may be calculated in terms of the autocorrelation function using the Wiener-Khinchin theorem. We here generalize the Wiener-Khinchin theo…
Underdamped stochastic heat engine at maximum efficiency
Andreas Dechant, Nikolai Kiesel, Eric Lutz
We investigate the performance of an underdamped stochastic heat engine for a time-dependent harmonic oscillator. We analytically determine the optimal protocol that maximizes the…
Nonergodic Diffusion of Single Atoms in a Periodic Potential
Farina Kindermann, Andreas Dechant, Michael Hohmann +5
Diffusion is a central phenomenon in almost all fields of natural science revealing microscopic processes from the observation of macroscopic dynamics. Here, we consider the paradi…
