Identifying essential genes in E. coli from a metabolic optimization principle
C. Martelli, A. De Martino, E. Marinari +2
Understanding the organization of reaction fluxes in cellular metabolism from the stoichiometry and the topology of the underlying biochemical network is a central issue in systems…
Cavity approach to the spectral density of non-Hermitian sparse matrices
Tim Rogers, Isaac Perez Castillo
The spectral densities of ensembles of non-Hermitian sparse random matrices are analysed using the cavity method. We present a set of equations from which the spectral density of a…
The two-spinon transverse structure factor of the gapped Heisenberg antiferromagnetic chain
J. -S. Caux, J. Mossel, I. Pérez Castillo
We consider the transverse dynamical structure factor of the anisotropic Heisenberg spin-1/2 chain (XXZ model) in the gapped antiferromagnetic regime (). Specializing to the…
Cavity Approach to the Spectral Density of Sparse Symmetric Random Matrices
Tim Rogers, Koujin Takeda, Isaac Pérez Castillo +1
The spectral density of various ensembles of sparse symmetric random matrices is analyzed using the cavity method. We consider two cases: matrices whose associated graphs are local…
Von Neumann's expanding model on random graphs
A De Martino, C Martelli, R Monasson +1
Within the framework of Von Neumann's expanding model, we study the maximum growth rate r achievable by an autocatalytic reaction network in which reactions involve a finite (fixed…
On the strategy frequency problem in batch Minority Games
A. De Martino, I. Perez Castillo, D. Sherrington
Ergodic stationary states of Minority Games with S strategies per agent can be characterised in terms of the asymptotic probabilities with which an agent uses of his stra…
