Avoiding Loopholes with Hybrid Bell-Leggett-Garg Inequalities [PDF]
, 2014 By combining the postulates of macrorealism with Bell locality, we derive a qualitatively different hybrid inequality that avoids two loopholes that commonly appear in Leggett-Garg and Bell inequalities.

Bell inequality and CP violation in the neutral kaon system [PDF]
, 2001 For the entangled neutral kaon system we formulate a Bell inequality sensitive to CP violation in mixing. Via this Bell inequality we obtain a bound on the leptonic CP asymmetry which is violated by experimental data.

Maximal violation of a broad class of Bell inequalities and its implication on self-testing
Physical Review Research, 2019 In quantum information, lifting is a systematic procedure that can be used to derive—when provided with a seed Bell inequality—other Bell inequalities applicable in more complicated Bell scenarios.

Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs
Journal of High Energy Physics, 2023 In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I 2), we show that, starting from an appropriate initial non-product state, the

Functional Bell inequalities can serve as a stronger entanglement witness [PDF]
, 2002 We consider a Bell inequality for a continuous range of settings of the apparatus at each site. This "functional" Bell inequality gives a better range of violation for generalized GHZ states.

Using complete measurement statistics for optimal device-independent randomness evaluation
New Journal of Physics, 2014 The majority of recent works investigating the link between non-locality and randomness, e.g. in the context of device-independent cryptography, do so with respect to some specific Bell inequality, usually the CHSH inequality.

Better Bell Inequality Violation by Collective Measurements [PDF]

Quantum analog of the original Bell inequality for two-qudit states with perfect correlations/anticorrelations [PDF]
, 2019 For an even qudit dimension $d\geq 2,$ we introduce a class of two-qudit states exhibiting perfect correlations/anticorrelations and prove via the generalized Gell-Mann representation that, for each two-qudit state from this class, the maximal violation ...

Bounds on Quantum Correlations in Bell Inequality Experiments [PDF]
, 2007 Bell inequality violation is one of the most widely known manifestations of entanglement in quantum mechanics; indicating that experiments on physically separated quantum mechanical systems cannot be given a local realistic description.
