A bstract We determine the Tomita-Takesaki modular data for CFTs in double cone and light
cone regions in conformally flat spacetimes. This includes in particular the modular …

We compute the relative entropy between the vacuum and a coherent state for a massive
scalar field in de Sitter spacetime, using Tomita-Takesaki modular theory and the Araki …

The scaling of local quantum entropies is of utmost interest for characterizing quantum fields,
many-body systems, and gravity. Despite their importance, theoretically and experimentally …

Thermodynamics can be developed from a microscopic starting point in terms of entropy and
the maximum entropy principle. We investigate here to what extent one can replace entropy …

Entropic uncertainty is a well-known concept to formulate uncertainty relations for
continuous variable quantum systems with finitely many degrees of freedom. Typically, the …

Quantum uncertainty relations are formulated in terms of relative entropy between
distributions of measurement outcomes and suitable reference distributions with maximum …

Information geometry provides differential geometric concepts like a Riemannian metric,
connections and covariant derivatives on spaces of probability distributions. We discuss …

Relative entropy is a powerful measure of the dissimilarity between two statistical field
theories in the continuum. In this work, we study the relative entropy between Gaussian …

The one-and two-boson momentum spectra are derived in the quantum local-equilibrium
canonical ensemble of noninteracting bosons with a fixed particle number constraint. We …

We review the calculations of the kinetic coefficients (thermal conductivity, shear viscosity,
momentum transfer rates) of the neutron star core matter within the framework of the Landau …
