Coarse-grained entropy and stimulated emission in curved space-time.
We study the entropy generation and particle production in scalar quantum field theory in expanding spacetimes with many-particle mixed initial states. The recently proposed coarse-grained entropy approach by Brandenberger et al. is applied to systems which may have a non-zero initial entropy. We find that although the particle production is amplified as a result of boson statistics, the (coars...
متن کاملNoise-level estimation of time series using coarse-grained entropy.
We present a method of noise-level estimation that is valid even for high noise levels. The method makes use of the functional dependence of coarse-grained correlation entropy K2(epsilon ) on the threshold parameter epsilon. We show that the function K2(epsilon ) depends, in a characteristic way, on the noise standard deviation sigma. It follows that observing K2 (epsilon ) one can estimate the...
متن کاملHigh-Resolution Coarse-Grained Modeling Using Oriented Coarse-Grained Sites.
We introduce a method to bring nearly atomistic resolution to coarse-grained models, and we apply the method to proteins. Using a small number of coarse-grained sites (about one per eight atoms) but assigning an independent three-dimensional orientation to each site, we preferentially integrate out stiff degrees of freedom (bond lengths and angles, as well as dihedral angles in rings) that are ...
متن کاملAccelerating the Requirement Space Exploration through Coarse-Grained Parallel Execution
The design and analysis of complex systems need to determine suitable configurations for meeting requirement constraints. The Monotonic Indices Space (MIS) method is a useful approach for monotonic requirement space exploration. However, the method is highly time and memory-Consuming. Aiming to the problem of low efficiency of sequential MIS method, this paper introduces a coarse-grained parall...
متن کاملPath-space variational inference for non-equilibrium coarse-grained systems
In this paper, we discuss information-theoretic tools for obtaining optimized coarse-grained molecular models for both equilibrium and non-equilibrium molecular dynamics. The latter are ubiquitous in physicochemical and biological applications, where they are typically associated with coupling mechanisms, multi-physics and/or boundary conditions. In general the non-equilibrium steady states are...
