Jamming, freezing and metastability in one-dimensional spin systems
G. De Smedt, C. Godreche, J. M. Luck
We consider in parallel three one-dimensional spin models with kinetic constraints: the paramagnetic constrained Ising chain, the ferromagnetic Ising chain with constrained Glauber…

Statistics of the occupation time for a class of Gaussian Markov processes
G. De Smedt, C. Godreche, J. M. Luck
We revisit the work of Dhar and Majumdar [Phys. Rev. E 59, 6413 (1999)] on the limiting distribution of the temporal mean $M_{t}=t^{-1}\int_{0}^{t}du \sign y_{u}$, for a Gaussian M…

Partial survival and inelastic collapse for a randomly accelerated particle
G. De Smedt, C. Godreche, J. M. Luck
We present an exact derivation of the survival probability of a randomly accelerated particle subject to partial absorption at the origin. We determine the persistence exponent and…
