Inferring the parameters of a Markov process from snapshots of the steady state
Simon Lee Dettmer, Johannes Berg
We seek to infer the parameters of an ergodic Markov process from samples taken independently from the steady state. Our focus is on non-equilibrium processes, where the steady sta…
Network inference in the non-equilibrium steady state
Simon L. Dettmer, H. Chau Nguyen, Johannes Berg
Non-equilibrium systems lack an explicit characterisation of their steady state like the Boltzmann distribution for equilibrium systems. This has drastic consequences for the infer…
Testing the Edwards hypothesis in spin systems under tapping dynamics
Johannes Berg, Silvio Franz, Mauro Sellitto
The Edwards hypothesis of ergodicity of blocked configurations for gently tapped granular materials is tested for abstract models of spin systems on random graphs and spin chains w…
Statistical mechanics of asset markets with private information
Johannes Berg, Matteo Marsili, Aldo Rustichini +1
Traders in a market typically have widely different, private information on the return of an asset. The equilibrium price of the asset may reflect this information more accurately…
On random graphs and the statistical mechanics of granular matter
Johannes Berg, Anita Mehta
The dynamics of spins on a random graph with ferromagnetic three-spin interactions is used to model the compaction of granular matter under a series of taps. Taps are modelled as t…
