Waiting time distribution for continuous stochastic systems (2014)
Journal Article
Gernert, R., Emary, C., & Klapp, S. H. (2014). Waiting time distribution for continuous stochastic systems. Physical review. E, Statistical, nonlinear, and soft matter physics, 90(6), Article 062115. https://doi.org/10.1103/PhysRevE.90.062115

The waiting time distribution (WTD) is a common tool for analyzing discrete stochastic processes in classical and quantum systems. However, there are many physical examples where the dynamics is continuous and only approximately discrete, or where it...

Testing macroscopic realism through high-mass interferometry (2014)
Journal Article
Emary, C., Cotter, J. P., & Arndt, M. (2014). Testing macroscopic realism through high-mass interferometry. Physical review. A, 90(4), Article 042114. https://doi.org/10.1103/PhysRevA.90.042114

We define a quantum witness for high-mass matter-wave interferometers that allows us to test fundamental assumptions of macroscopic realism. We propose an experimental realization using absorptive laser gratings and show that such systems can strongl... Read More about Testing macroscopic realism through high-mass interferometry.

Temporal quantum correlations and Leggett-Garg inequalities in multilevel systems (2014)
Journal Article
Budroni, C., & Emary, C. (2014). Temporal quantum correlations and Leggett-Garg inequalities in multilevel systems. Physical review letters, 113(5), Article 050401. https://doi.org/10.1103/PhysRevLett.113.050401

We show that the quantum bound for temporal correlations in a Leggett-Garg test, analogous to the Tsirelson bound for spatial correlations in a Bell test, strongly depends on the number of levels N that can be accessed by the measurement apparatus vi...
