Thermodynamics of quantum jump trajectories in systems driven by classical fluctuations
, 2010 The large-deviation method can be used to study the measurement trajectories of open quantum systems. For optical arrangements this formalism allows to describe the long time properties of the (non-equilibrium) photon counting statistics in the context ...

A convergent expansion of the Airy's integral with incomplete Gamma functions
, 2020 There are two main power series for the Airy functions, namely the Maclaurin and the asymptotic expansions. The former converges for all finite values of the complex variable, $z$, but it requires a large number of terms for large values of $|z|$, and ...
