On the action principle as a guide to substantive general covariance
Ward Struyve
While Einstein was guided by the principle of general covariance in formulating general relativity, Kretschmann later argued that this principle lacks physical significance, since…
Absence of gravitationally induced entanglement in certain semi-classical theories of gravity
Ward Struyve
Bose et al. and Marletto and Vedral proposed an experiment to test whether gravity can induce entanglement between massive systems, arguing that the capacity to do so would imply t…
On substantive Lorentz invariance and quantum theory
Ward Struyve
Lorentz invariance is considered a fundamental property of relativistic quantum theory. However, in standard quantum theory this invariance is only partially realized: while relati…
Zig-zag dynamics in a Stern-Gerlach spin measurement
Simon Krekels, Christian Maes, Kasper Meerts +1
The one-century-old Stern-Gerlach setup is paradigmatic for a quantum measurement. We visualize the electron trajectories following the Bohmian zig-zag dynamics. This dynamics was…
Scope of the action principle
Ward Struyve
Laws of motion given in terms of differential equations can not always be derived from an action principle, at least not without introducing auxiliary variables. By allowing auxili…
The Bohmian solution to the problem of time
Ward Struyve
In canonical quantum gravity the wave function of the universe is static, leading to the so-called problem of time. We summarize here how Bohmian mechanics solves this problem.
