In the study of open quantum systems, the polaron transformation has recently attracted a renewed interest as it offers the possibility to explore the strong system-bath coupling regime. Despite this ...
Stochastic theory of large-scale enzyme-reaction networks: Finite copy number corrections to rate equation models
Stochastic theory large-scale enzyme-reaction networks Finite copy number corrections
2011/8/18
Abstract: Chemical reactions inside cells occur in compartment volumes in the range of atto- to femtolitres. Physiological concentrations realized in such small volumes imply low copy numbers of inter...
