Hysteretic response to different modes of ramping an external field in sparse and dense Ising spin glasses
Mahajabin Rahman, Stefan Boettcher
We consider the hysteretic behavior of Ising spin glasses at for various modes of driving. Previous studies mostly focused on an infinitely slow speed by which the…
Inferring Local Structure from Pairwise Correlations
Mahajabin Rahman, Ilya Nemenman
To construct models of large, multivariate complex systems, such as those in biology, one needs to constrain which variables are allowed to interact. This can be viewed as detectin…
Real-space model for activated processes in rejuvenation and memory behavior of glassy systems
Mahajabin Rahman, Stefan Boettcher
We offer an alternative real-space description, based purely on activated processes, for the understanding of relaxation dynamics in hierarchical landscapes. To this end, we use th…
Analysis of landscape hierarchy during coarsening and aging in Ising spin glasses
Stefan Boettcher, Mahajabin Rahman
We use record dynamics (RD), a coarse-grained description of the ubiquitous relaxation phenomenology known as "aging", as a diagnostic tool to find universal features that distingu…
Quantum Clustering and Gaussian Mixtures
Mahajabin Rahman, Davi Geiger
The mixture of Gaussian distributions, a soft version of k-means , is considered a state-of-the-art clustering algorithm. It is widely used in computer vision for selecting classes…
