An \(\mathbb R^d\)-valued stochastic process \((X(t))_{t\geq 0}\) is said to be a Levy process provided it has time homogeneous and independent increments. A detailed investigation of those processes may be found in the book of J. Bertoin [“Lévy processes” (1996; Zbl 0861.60003)]. Among Lévy processes the class of stable ones is of special interest and importance. Recall that they enjoy certain self-similarity properties. The aim of the present paper is to review a number of physical phenomena for which Lévy processes and, in particular, stable processes can be used as a reasonable model. The examples are from fluid mechanics, solid state physics, polymer chemistry and mathematical finance. For certain nonlinear problems, asymptotic and approximation schemes are discussed.
