Gravity models of networks: Integrating maximum-entropy and econometric approaches
Physical Review Research, 2022 The World Trade Web (WTW) is the network of international trade relationships among world countries. Characterizing both the local link weights (observed trade volumes) and the global network structure (large-scale topology) of the WTW via a single model

On the Nature of Information: How FAIR Digital Objects are Building-up Semantic Space [PDF]
Research Ideas and Outcomes, 2022 In this paper, we are concerned about the nature of information and how to gather and compose data with the help of so called FAIR digital objects (FDOs) in order to transform them to knowledge. FDOs are digital surrogates of real objects.

Characterizations of Chemical Networks Entropies by K-Banhatii Topological Indices
Symmetry, 2023 Entropy is a thermodynamic function in physics that measures the randomness and disorder of molecules in a particular system or process based on the diversity of configurations that molecules might take.

R\'enyi generalizations of quantum information measures [PDF]
, 2014 Quantum information measures such as the entropy and the mutual information find applications in physics, e.g., as correlation measures. Generalizing such measures based on the R\'enyi entropies is expected to enhance their scope in applications.

The measure of irregularities of nanosheets
Open Physics, 2020 Nanosheets are two-dimensional polymeric materials, which are among the most active areas of investigation of chemistry and physics. Many diverse physicochemical properties of compounds are closely related to their underlying molecular topological ...

Topological R\'enyi entropy after a quantum quench [PDF]
, 2013 We present an analytical study on the resilience of topological order after a quantum quench. The system is initially prepared in the ground state of the toric-code model, and then quenched by switching on an external magnetic field.

Topological insulators with arbitrarily tunable entanglement [PDF]
, 2014 We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to demonstrate that the area law contribution can be tuned to an arbitrarily ...
