Anomalous scaling and phase transition in large deviations of dynamical observables of stationary Gaussian processes

Alexander Valov, Baruch Meerson

We study large deviations, over a long time window $T \to \infty$ , of the dynamical observables $A_{n} = \int_{0}^{T} x^{n} (t) d t$ , $n = 3, 4, \dots$ , where $x (t)$ is a centered stationary…

Dynamical large deviations of the fractional Ornstein-Uhlenbeck process

Alexander Valov, Baruch Meerson

The fractional Ornstein-Uhleneck (fOU) process is described by the overdamped Langevin equation $x ˙ (t) + γ x = 2 D ξ (t)$ , where $ξ (t)$ is the fractional Gaussian noise with t…

Thermally activated particle motion in biased correlated Gaussian disorder potentials

Alexander Valov, Netanel Levi, Baruch Meerson

Thermally activated particle motion in disorder potentials is controlled by the large- $Δ V$ tail of the distribution of height $Δ V$ of the potential barriers created by the disorder…

Large deviations and phase transitions in spectral linear statistics of Gaussian random matrices

Alexander Valov, Baruch Meerson, Pavel V. Sasorov

We evaluate, in the large- $N$ limit, the complete probability distribution $P (A, m)$ of the values $A$ of the sum $\sum_{i = 1}^{N} ∣ λ_{i} ∣^{m}$ , where $λ_{i}$ ( $i = 1, 2, \dots, N$ )…
