Energetics and performance of a microscopic heat engine based on exact calculations of work and heat distributions

We investigate a microscopic motor based on an externally controlled two-level system. We give the exact solution of the underlying dynamical equation and discuss in detail the emerging thermodynamics. We also calculate the probability densi...

Probability estimates of extreme temperature events: stochastic modelling approach vs. extreme value distributions.

The paper deals with probability estimates of temperature extremes (annual temperature maxima and heat waves) in the Czech Republic. Two statistical methods of the probability estimations are compared; one based on the stoc...
