Small fluctuations in epitaxial growth via conservative noise
Small fluctuations epitaxial growth conservative noise
2015/10/16
We study the combined effect of growth (material deposition from above) and nearest-neighbor entropic and force-dipole interactions in a stochastically perturbed system of N line defects (steps) on a ...
Mechanism of Hollow Nanoparticle Formation Due to Shape Fluctuations
Hollow Nanoparticle Formation Shape Fluctuations
2015/10/16
Shape fluctuations in nanoparticles strongly influence their stability. Here, we introduce a quantitative model of such shape fluctuations and apply this model to the important case of Pt-shell/transi...
Bose-Einstein condensation, fluctuations, and recurrence relations in statistical mechanics
Gas bose Einstein condensation partition function condensation
2014/12/20
We calculate certain features of Bose–Einstein condensation in the ideal gas by using recurrence relations for the partition function. The grand canonical ensemble gives inaccurate results for certain...

Energy fluctuations, hydrodynamics and local correlations in harmonic systems with bulk noises
Energy fluctuations hydrodynamics local correlations harmonic systems Mathematical Physics
2012/6/12
In this note, I summarise and comment on joint work with C. Bernardin, V. Kannan and J. L. Lebowitz concerning two harmonic systems with bulk noises whose nonequilibrium steady states (NESS) are nearl...
Explanation of quantum interference: Classical trajectories plus ballistic diffusion caused by zero-point fluctuations
quantum mechanics, ballistic di usion, nonequilibrium thermodynamics, zero-point
2011/9/29
A purely classical explanation of quantum mechanical interference is given. We claim that for every single \particle" a thermal context can be de ned, which re ects its embedding within boundary condi...
Sharp asymptotics for Toeplitz determinants, fluctuations and the gaussian free field on a Riemann surface
Sharp asymptotics fluctuations the gaussian free Riemann surface
2011/7/26
Abstract: We consider canonical determinantal point processes with N particles on a compact Riemann surface X defined with respect to the constant curvature metric and show that in the large N-limit t...

2011/7/26
Abstract: These lecture notes provide an elementary introduction, within the framework of finite quantum systems, to recent developments in the theory of entropic fluctuations.
Fluctuations of Matrix Entries of Regular Functions of Sample Covariance Random Matrices
Matrix Entries Sample Covariance Random Matrices Probability
2011/7/27
Abstract: We extend the results about the fluctuations of the matrix entries of regular functions of Wigner matrices to the case of sample covariance random matrices.
Particle number fluctuations and correlations in transfer reactions obtained using the Balian-Veneroni variational principle
Particle number fluctuations correlations transfer reactions obtained Balian-Veneroni variational principle
2011/1/6
The Balian-V´en´eroni (BV) variational principle, which optimizes the evolution of the state ac-cording to the relevant observable in a given variational space, is used at the mean-field l...
A Note on Non-equilibrium Work Fluctuations and Equilibrium Free Energies
Classical Statistical Mechanics Thermodynamics Non-equilibrium and Irreversible Thermodynamics
2010/11/24
We consider in this paper, a few important issues in non-equilibrium work fluctuations and
their relations to equilibrium free energies. First we show that Jarzynski identity can be viewed as a cumul...
Nonequilibrium Fluctuations in a Gaussian Galton Board (or Periodic Lorentz Gas) Using Long Periodic Orbits
Galton Board Lyapunov Spectrum Fluctuations Nonequilibrium
2010/11/19
Predicting nonequilibrium fluctuations requires a knowledge of nonequilibrium distribution functions.Despite the distributions’ fractal character some theoretical results, “Fluctuation Theorems”,remin...
Statistical and dynamical fluctuations in the ratios of higher cumulants in relativistic heavy ion collisions
Statistical and dynamical fluctuations ratios of higher cumulants relativistic heavy ion collisions
2011/1/6
With the help of transport and statistical models, we find that the ratios of higher net-proton
cumulants measured at RHIC are dominated by the statistical fluctuations. Future measurements
should f...
Structures of nonequilibrium fluctuations: dissipation and activity
Structures of nonequilibrium fluctuations dissipation activity
2010/11/24
We discuss research done in two important areas of nonequilibrium statistical mechanics: fluctuation dissipation relations and dynamical fluctuations. The work discussed here was reported before in [2...
Quantum fluctuations can promote or inhibit glass formation
Quantum fluctuations can glass formation
2010/11/17
The very nature of glass is somewhat mysterious: while relaxation times in glasses are of
sufficient magnitude that large-scale motion on the atomic level is essentially as slow as it is in the cryst...
