Matching Statistics of an Itô Process by a Process of Diffusion Type
Matching Statistics Process of Diffusion Type
2010/11/8
Suppose we are given a multi-dimensional It\^o process, which can be regarded as a model for an underlying asset price together with related stochastic processes, e.g., volatility. The drift and diff...
Excursion Sets and Non-Gaussian Void Statistics
Excursion Sets Non-Gaussian Void Statistics
2010/11/11
Primordial non-Gaussianity (NG) affects the large scale structure (LSS) of the universe by leaving an imprint on the distribution of matter at late times. Much attention has been focused on using the ...
Poisson Statistics in the High Temperature QCD Dirac Spectrum
Poisson Statistics High Temperature QCD Dirac Spectrum
2011/1/14
At low temperature in the epsilon regime of QCD the low-end of the Dirac spectrum is described
by random matrix theory. In contrast, there has been no similarly well established staistical descriptio...
Statistics of polymer extensions in turbulent channel flow
Statistics of polymer extensions turbulent channel flow
2010/11/17
We present direct numerical simulations~(DNSs) of turbulent channel flow with passive Lagrangian polymers. To understand the polymer behavior we investigate the behavior of infinitesimal line elements...
We study polytopes that are convex hulls of vectors of subgraph densities. Many graph theoretical questions can be expressed in terms of these polytopes, and statisticians use them to understand expon...
The effect of Coulombic friction on spatial displacement statistics
Coulombic friction spatial displacement statistics
2010/11/12
The phenomenon of Coulombic friction enters the stochastic description of dry friction between two solids and the statistic characterization of vibrating granular media. Here we analyze the correspon...
The Schrödinger equation for the evolution of isolated quantum systems determines the constants
of motion for the dynamical problem, which can be identified with the populations along the
princ...
Transformation & Uncertainty. Some Thoughts on Quantum Probability Theory, Quantum Statistics, and Natural Bundles
Quantum Probability Theory Quantum Statistics Natural Bundles
2010/11/19
This PHD thesis is concerned with uncertainty relations in quantum probability theory, state estimation in quantum stochastics, and natural bundles in differential geometry. After some comments on the...
Spectral statistics for random Schrödinger operators in the localized regime
Spectral statistics random Schrö dinger operators the localized regime
2010/11/15
We study various statistics related to the eigenvalues and eigenfunctions of random Hamiltonians in the localized regime. Consider a random Hamiltonian at an energy $E$ in the localized phase. Assume ...
From super-radiance to super-transmittance: An application of Full Counting Statistics to the Dicke model
Lindblad form stationary state dissipation heat transport
2010/11/8
The application of Full Counting Statistics to a Dicke super-radiant model allows us to obtain an accurate description of the number of radiated bosons in the transient regime. This includes for examp...
Majorana meets Coxeter: Non-Abelian Majorana Fermions and Novel Non-Abelian Statistics
Majorana meets Coxeter Non-Abelian Majorana Fermions Novel Non-Abelian Statistics
2010/11/11
Statistics of particles is one of the most fundamental aspects of quantum systems. Majorana fermions in vortices on a two-dimensional plane obey novel statistics called non-Abelian statistics. Non-Abe...
Quantum dynamics (e.g., the Schr\"odinger equation) and classical dynamics (e.g., Hamilton equations) can both be formulated in equal geometric terms: a Poisson bracket defined on a manifold. The diff...
RFI excision using a higher order statistics analysis of the power spectrum
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/24
A method of radio frequency interference (RFI) suppression in radio astronomy spectral observations is described based on the analysis of the probability distribution of an instantaneous spectrum.
Counting Statistics of Many-Particle Quantum Walks
Counting Statistics Many-Particle Quantum Walks
2010/10/21
We study quantum walks of many non-interacting particles on a beam splitter array. Single as well as multi-mode counting statistics are obtained for generic input states. Bosonic interference e ects a...

Full Counting Statistics Stationary Particle Beams
2010/10/18
We present a general scheme for treating particle beams, including stationary beams, as many
particle systems. This includes the full counting statistics and the requirements of Bose/Fermi
symmetry....
