Entanglement entropy production in gravitational collapse: covariant regularization and solvable models
Eugenio Bianchi, Tommaso De Lorenzo, Matteo Smerlak
We study the dynamics of vacuum entanglement in the process of gravitational collapse and subsequent black hole evaporation. In the first part of the paper, we introduce a covarian…
Thermodynamics of inequalities: from precariousness to economic stratification
Matteo Smerlak
Growing economic inequalities are observed in several countries throughout the world. Following Pareto, the power-law structure of these inequalities has been the subject of much t…
Last gasp of a black hole: unitary evaporation implies non-monotonic mass loss
Eugenio Bianchi, Matteo Smerlak
We show within the usual two-dimensional approximation that unitarity and the restoration of Minkowski vacuum correlations at the end of black hole evaporation impose unexpected co…
Entanglement entropy and negative energy in two dimensions
Eugenio Bianchi, Matteo Smerlak
It is well known that quantum effects can produce negative energy densities, though for limited times. Here we show in the context of two-dimensional CFT that such negative energy…
Mapping systemic risk: critical degree and failures distribution in financial networks
Matteo Smerlak, Brady Stoll, Agam Gupta +1
The 2008 financial crisis illustrated the need for a thorough, functional understanding of systemic risk in strongly interconnected financial structures. Dynamic processes on compl…
