Large-scale quantum effects have always played an important role in the foundations of
quantum theory. With recent experimental progress and the aspiration for quantum …

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 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 …

The search for empirical schemes to evidence the nonclassicality of large masses is a
central quest of current research. However, practical schemes to witness the irreducible …

Macroscopic realism, the classical world view that macroscopic objects exist independently
of and are not influenced by measurements, is usually tested using Leggett-Garg …

The present work is devoted to the characterization of the Leggett-Garg inequality (LGI) for
three flavored neutrino oscillations in the presence of both matter and charge-conjugation …

Can the most “classical-like” of all quantum states, namely the Schrödinger coherent state of
a harmonic oscillator, exhibit nonclassical behavior? We find that for an oscillating object …

Macrorealism (MR) is the worldview that certain quantities may take definite values at all
times irrespective of past or future measurements and may be experimentally falsified via the …

We show unambiguous violations of the different macrorealist inequalities, like the Leggett-
Garg inequality (LGI) and its variant called Wigner's form of the Leggett-Garg inequality …

We consider two different types of conditions which were proposed to test macrorealism in
the context of a system described by a single dichotomic variable Q. This is the view that a …
