Non-linear susceptibilities of spherical models
Leticia F. Cugliandolo, David S. Dean, Hajime Yoshino
The static and dynamic susceptibilities for a general class of mean field random orthogonal spherical spin glass models are studied. We show how the static and dynamical properties…
Hysteresis behavior of the random-field Ising model with 2-spin-flip dynamics: Exact results on a Bethe lattice
Xavier Illa, Martin-Luc Rosinberg, Gilles Tarjus
We present an exact treatment of the hysteresis behavior of the zero-temperature random-field Ising model on a Bethe lattice when it is driven by an external field and evolved acco…
The magnetization-driven random field Ising model at T=0
Xavier Illa, Martin-Luc Rosinberg, Prabodh Shukla +1
We study the hysteretic evolution of the random field Ising model (RFIM) at T=0 when the magnetization M is controlled externally and the magnetic field H becomes the output variab…
Influence of the driving mechanism on the response of systems with athermal dynamics: the example of the random-field Ising model
Xavier Illa, Martin-Luc Rosinberg, Eduard Vives
We investigate the influence of the driving mechanism on the hysteretic response of systems with athermal dynamics. In the framework of local-mean field theory at finite temperatur…
Rigidity and intermediate phases in glasses driven by speciation
Matthieu Micoulaut
The rigid to floppy transitions and the associated intermediate phase in glasses are studied in the case where the local structure is not fully determined from the macroscopic conc…
Non-perturbative phenomena in the three-dimensional random field Ising model
Victor Dotsenko
The systematic approach for the calculations of the non-perturbative contributions to the free energy in the ferromagnetic phase of the random field Ising model is developed. It is…
