Spatial and topological organization of DNA chains induced by gene co-localization
Ivan Junier, Olivier Martin, François Képès
Transcriptional activity has been shown to relate to the organization of chromosomes in the eukaryotic nucleus and in the bacterial nucleoid. In particular, highly transcribed gene…
Magnetic exponents of two-dimensional Ising spin glasses
F. Liers, O. C. Martin
The magnetic critical properties of two-dimensional Ising spin glasses are controversial. Using exact ground state determination, we extract the properties of clusters flipped when…
The Statistics of the Number of Minima in a Random Energy Landscape
Satya N. Majumdar, Olivier C. Martin
We consider random energy landscapes constructed from d-dimensional lattices or trees. The distribution of the number of local minima in such landscapes follows a large deviation p…
Temperature Chaos in Two-Dimensional Ising Spin Glasses with Binary Couplings: a Further Case for Universality
Jovanka Lukic, Enzo Marinari, Olivier C. Martin +1
We study temperature chaos in a two-dimensional Ising spin glass with random quenched bimodal couplings, by an exact computation of the partition functions on large systems. We stu…
Finite size scaling in Villain's fully frustrated model and singular effects of plaquette disorder
J. Lukic, E. Marinari, O. C. Martin
The ground state and low T behavior of two-dimensional spin systems with discrete binary couplings are subtle but can be analyzed using exact computations of finite volume partitio…
Probing spin glasses with heuristic optimization algorithms
Olivier C. Martin
A sketch of the chapter appearing under the same heading in the book ``New Optimization Algorithms in Physics'' (A.K. Hartmann and H. Rieger, Eds.) is given. After a general introd…
