On Stochastic Error and Computational Efficiency of the Markov Chains Monte Carlo Method
Monte Carlo simulation phase coexistence Gibbs ensemble molecular simulation multi-component system
2012/4/24
In Monte Carlo simulations, the thermal equilibria quantities are estimated by ensemble average over a sample set containing a large number of correlated samples. As the stochastic error of the simula...
Markov evolutions and hierarchical equations in the continuum: II. Multicomponent systems
Continuous system Markov generator Markov process Stochastic dynamics Configuration spaces Birth-and-death process
2011/7/26
Abstract: General birth-and-death as well as hopping stochastic dynamics of infinite multicomponent particle systems in the continuum are considered. We derive the corresponding evolution equations fo...
Markov property of determinantal processes with extended sine, Airy, and Bessel kernels
Determinantal processes Correlation kernels Random matrix theory Infinite particle systems Markov property
2011/7/28
Abstract: When the number of particles is finite, the noncolliding Brownian motion (the Dyson model) and the noncolliding squared Bessel process are determinantal diffusion processes for any determini...
Geometric Allocation Approach for Transition Kernel of Markov Chain
Markov chain, Transition kernel, Geometric allocation, Detailed balance, Reversibility
2011/9/14
We introduce a new geometric approach that constructs a transition kernel of Markov chain. Our method always minimizes the average rejection rate and even reduce it to zero in many relevant cases,whic...

Markov processes of infinitely many nonintersecting random walks
Markov processes nonintersecting random walk Probability
2011/7/27
Abstract: Consider an N-dimensional Markov chain obtained from N one-dimensional random walks by Doob h-transform with the q-Vandermonde determinant. We prove that as N becomes large, these Markov cha...
Finding and testing network communities by lumped Markov chains
networks communities Markov chains random walks
2011/8/29
Identifying communities (or clusters), namely groups of nodes with comparatively strong internal connectivity, is a fundamental task for deeply understanding the structure and function of a network. Y...
In a quantum Markov chain, the temporal succession of states is modeled by the repeated action of a ``bistochastic quantum operation" on the density matrix of a quantum system. Based on this conceptua...
Cyclic Markov chains with an application to an intermediate ENSO model
Cyclic Markov chains application intermediate ENSO model
2009/11/12
We develop the theory of cyclic Markov chains and apply it to the El Niño-Southern Oscillation (ENSO) predictability problem. At the core of Markov chain modelling is a partition of the state s...
Time series segmentation with shifting means hidden markov models
Time series segmentation shifting means markov models
2009/11/9
We present a new family of hidden Markov models and apply these to the segmentation of hydrological and environmental time series. The proposed hidden Markov models have a discrete state space and the...
The Algebraic Measure of a Hidden Markov Quantum Memory Channel
Algebraic a Hidden Markov Quantum Memory Channel
2010/4/8
This paper was presented in poster form at and in the proceedings of the QCMC 2008. It is a summary of a fuller paper to appear separately. The classical product state capacity of a noisy quantum chan...
布朗运动中的量子及非Markov效应
非Markov效应 量子 布朗运动
2008/12/2
本文采用路径积分方法,在谐振子相互作用模型下得到了密度矩阵ρ(x,x,t),计算了坐标二阶矩,并与经典结果进行了比较.在Markov近似下,我们得到了Fokker-Planck方程的量子修正,讨论系统的非Markov行为,我们建议采用具有量子关联条件的Langevin方程并给出了它的形式.
On Empty Essential Spectrum for Markov Processes in Dimension One
Markov generator Essential spectrum Compact embedding Hardy-type inequality
2007/12/12
This paper gives characterizations for diffusion processes on the line and birth--death processes whose generators admit the empty essential spectra. Some equivalent conditions for empty essential spe...
