Universal singularities of anomalous diffusion in the Richardson class
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Inhomogeneous environments are rather ubiquitous in nature, often implying anomalies resulting in deviation from Gaussianity of diffusion processes. While sub- and superdiffusion a…
Anomalous dynamical scaling determines universal critical singularities
Attilio L. Stella, Aleksei Chechkin, Gianluca Teza
Anomalous diffusion phenomena occur on length scales spanning from intracellular to astrophysical ranges. A specific form of decay at large argument of the probability density func…
Eigenvalue crossing as a phase transition in relaxation dynamics
Gianluca Teza, Ran Yaacoby, Oren Raz
When a system's parameter is abruptly changed, a relaxation towards the new equilibrium of the system follows. We show that a crossing between the second and third eigenvalues of t…
Far from equilibrium relaxation in the weak coupling limit
Ran Yaacoby, Oren Raz, Gianluca Teza
It is commonly assumed that a large system, weakly coupled to a thermal environment through its boundaries, relaxes quasistatically towards the new equilibrium even when the temper…
