Multiplicative white noise functionals and the Krylov-Veretennikov expansion for coalescing stochastic flows
Krylov-Veretennikov expansion coalescing stochastic flows Probability
2011/9/20
Abstract: In this article we consider multiplicative operator-valued white noise functionals related to a stochastic flow. A generalization of the Krylov-Veretennikov expansion is presented. An analog...
Offset frequency dynamics and phase noise properties of a self-referenced 10 GHz Ti:sapphire frequency comb
Offset frequency dynamics phase noise properties self-referenced 10 GHz sapphire frequency comb
2011/8/11
Abstract: This paper shows the experimental details of the stabilization scheme that allows full control of the repetition rate and the carrier-envelope offset frequency of a 10 GHz frequency comb bas...
Analysis of noise-induced bistability in Michaelis Menten single-step enzymatic cycle
noise-induced bistability Michaelis Menten single-step enzymatic cycle
2011/8/11
Abstract: In this paper we study noise-induced bistability in a specific circuit with many biological implications, namely a single-step enzymatic cycle described by Michaelis Menten equations with qu...
Negative Backaction Noise in Interferometric Detection of a Microlever
Negative Backaction Noise Interferometric Detection Microlever
2011/8/11
Abstract: Interferometric detection of mirror displacements is intrinsically limited by laser shot noise. In practice, however, it is often limited by thermal noise. Here we report on an experiment pe...
Photon noise limited radiation detection with lens-antenna coupled Microwave Kinetic Inductance Detectors
Photon noise limited radiation Microwave Kinetic Inductance Detectors
2011/10/13
Microwave Kinetic Inductance Detectors (MKIDs) have shown great potential for sub-mm instrumentation because of the high scalability of the technology. Here we demonstrate for the first time in the su...
We show how sign problems in simulations of many-body systems can manifest themselves in the form of heavy-tailed correlator distributions, similar to what is seen in electron propagation through diso...
Transport equations with fractal noise - existence, uniqueness and regularity of the solution
Stochastic partial differential equations Transport equation Nonsmooth coefficients Fractional Brownian noise
2011/9/15
Abstract: The main result of the present paper is a statement on existence, uniqueness and regularity for mild solutions to a parabolic transport diffusion type equation that involves a non-smooth coe...
Pulsar state switching, timing noise and free precession
dense matter – stars: neutron – stars: oscillations – stars: pulsars –stars: rotation
2011/10/10
Recent radio pulsar observations have shown that a number of pulsars display interesting long term periodicities in their spin-down rates. At least some of these pulsars also undergo sharp changes in ...
Noise as a Boolean algebra of sigma-fields. I. Completion
Noise Boolean algebra of sigma-fields Probability
2011/9/9
Abstract: Nonclassical noises over the plane (such as the black noise of percolation) consist of sigma-fields corresponding to some planar domains. One can treat less regular domains as limits of more...

Increased Brownian force noise from molecular impacts in a constrained volume
Brownian force noise molecular impacts constrained volume
2011/8/17
Abstract: We report on residual gas damping of the motion of a macroscopic test mass enclosed in a nearby housing in the molecular flow regime. The damping coefficient, and thus the associated thermal...
