Marked random graphs with given degree sequence: large deviations on the local topology

Rangel Baldasso, Alan Pereira, Guilherme Reis

We investigate the behavior of the empirical neighborhood distribution of marked graphs in the framework of local weak convergence. Here we extend known results by considering unif…

Large deviations for marked sparse random graphs with applications to interacting diffusions

Rangel Baldasso, Roberto I Oliveira, Alan Pereira +1

We consider the empirical neighborhood distribution of marked sparse Erdős-Rényi random graphs, obtained by decorating edges and vertices of a sparse Erdős-Rényi random graph w…

Distinguishing Ordered Phases using Machine Learning and Classical Shadows

Leandro Morais, Tiago Pernambuco, Rodrigo G. Pereira +3

Classifying phase transitions is a fundamental and complex challenge in condensed matter physics. This work proposes a framework for identifying quantum phase transitions by combin…

Photo-Assisted Pd-Nb2O5/Carbon Nanocomposites for Enhanced Ethanol Electro-Oxidation Kinetics and CO Tolerance in Alkaline Media

João V. T. Neves, Stephanie S. Aristides-Barros, Aline B. Trench +4

Pd-based anodes for alcohol oxidation suffer from surface poisoning and sluggish kinetics. Here, we developed Pd-Nb2O5/C nanocomposites to improve ethanol electrooxidation kinetics…
