Phase Transitions and Order Parameters in Correlation Matrices: A Wishart-Ensemble Perspective on the Largest Eigenvalue
Roberto da Silva, Antonio Mihara, Henrique Tramontina +1
We investigate the properties of the largest eigenvalue of correlation matrices within the framework of Wishart ensembles. In this work, we propose the largest eigenvalue as an eff…

Crossover effects on the phase transitions phenomena translated by arborecences and spectral properties
Roberto da Silva
This study investigates how visibility graphs constructed from Monte Carlo Markov Chain time series of spin models capture the critical behavior of the system. More precisely, we s…
