We investigate Leggett-Garg inequalities for neutrino oscillations in the quantum field
theoretical setting. We derive an exact flavor-mass uncertainty relation and prove that this …

We introduce a framework unifying the mathematical characterisation of different measures
of general quantum resources and allowing for a systematic way to define a variety of faithful …

We report on a systematic study on the entanglement between helicity degrees of freedom
generated at tree level in quantum electrodynamics two-particle scattering processes. We …

Flavor oscillations in elementary particle physics are related to multimode entanglement of
single-particle states. We show that mode entanglement can be expressed in terms of flavor …

It was shown that the particle distribution detected by a uniformly accelerated observer in the
inertial vacuum (Unruh effect) deviates from the pure Planckian spectrum when considering …

We investigate sharing of bipartite entanglement in a scenario where half of an entangled
pair is possessed and projectively measured by one observer, called Alice, while the other …

An exactly solvable Kitaev model in a two-dimensional square lattice exhibits a topological
quantum phase transition which is different from the symmetry-breaking transition at zero …

In this paper, we propose the geometric mean of bipartite concurrences as a genuine
multipartite entanglement measure. This measure achieves the maximum value for …

We consider two necessary and sufficient conditions for macrorealism recently appeared in
the literature, known as no-signaling-in-time and arrow-of-time conditions, respectively, and …

Many-body quantum systems can be characterized using the notions of k-separability and
entanglement depth. A quantum state is k-separable if it can be expressed as a mixture of k …
