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…
Double-slit experiment revisited
Siddhant Das, Dirk-André Deckert, Leopold Kellers +2
The double-slit experiment is one of the quintessential quantum experiments. However, it tends to be overlooked that a theoretical account of this experiment requires the specifica…
Real surreal trajectories in pilot-wave hydrodynamics
Valeri Frumkin, David Darrow, Ward Struyve +1
In certain instances, the particle paths predicted by Bohmian mechanics are thought to be at odds with classical intuition. A striking illustration arises in the interference exper…
Questioning the adequacy of certain quantum arrival-time distributions
Siddhant Das, Ward Struyve
It is shown that a class of exponentially decaying time-of-arrival probability distributions suggested by Włodarz, Marchewka and Schuss, and Jurman and Nikolić, as well as a semicl…
Comparison of the mean field and Bohmian semi-classical approximations to the Rabi model
Dirk-André Deckert, Leopold Kellers, Travis Norsen +1
Bohmian mechanics is an alternative to standard quantum mechanics that does not suffer from the measurement problem. While it agrees with standard quantum mechanics concerning its…
Typicality in the foundations of statistical physics and Born's rule
Detlef Dürr, Ward Struyve
Typicality has always been in the minds of the founding fathers of probability theory when probabilistic reasoning is applied to the real world. However, the role of typicality is…
Bohmian trajectories for the half-line barrier
Remy Dubertrand, Jeong-Bo Shim, Ward Struyve
Bohmian trajectories are considered for a particle that is free (i.e. the potential energy is zero), except for a half-line barrier. On the barrier, both Dirichlet and Neumann boun…
Chaotic Bohmian trajectories for stationary states
A. Cesa, J. Martin, W. Struyve
In Bohmian mechanics, the nodes of the wave function play an important role in the generation of chaos. However, so far, most of the attention has been on moving nodes; little is k…
Semi-classical approximations based on Bohmian mechanics
Ward Struyve
Semi-classical theories are approximations to quantum theory that treat some degrees of freedom classically and others quantum mechanically. In the usual approach, the quantum degr…
Bohmian Mechanics for a Degenerate Time Foliation
Ward Struyve, Roderich Tumulka
The version of Bohmian mechanics in relativistic space-time that works best, the hypersurface Bohm--Dirac model, assumes a preferred foliation of space-time into spacelike hypersur…
On quantum potential dynamics
Sheldon Goldstein, Ward Struyve
Non-relativistic de Broglie-Bohm theory describes particles moving under the guidance of the wave function. In de Broglie's original formulation, the particle dynamics is given by…
Bohmian Trajectories For a Time Foliation with Kinks
Ward Struyve, Roderich Tumulka
This paper concerns the hypersurface Bohm-Dirac model, i.e., the version of Bohmian mechanics in a relativistic space-time proposed by Dürr et al. [1], which assumes a preferred fo…
Can Bohmian mechanics be made relativistic?
Detlef Dürr, Sheldon Goldstein, Travis Norsen +2
In relativistic space-time, Bohmian theories can be formulated by introducing a privileged foliation of space-time. The introduction of such a foliation - as extra absolute space-t…
Weak Measurement and (Bohmian) Conditional Wave Functions
Travis Norsen, Ward Struyve
It was recently pointed out (and demonstrated experimentally) by Lundeen et al. that the wave function of a particle (more precisely, the wave function possessed by each member of…
On the zig-zag pilot-wave approach for fermions
Ward Struyve
We consider a pilot-wave approach for the Dirac theory that was recently proposed by Colin and Wiseman. In this approach, the particles perform a zig-zag motion, due to stochastic…
Pilot-wave approaches to quantum field theory
Ward Struyve
The purpose of this paper is to present an overview of recent work on pilot-wave approaches to quantum field theory. In such approaches, systems are not only described by their wav…
Quantum non-equilibrium and relaxation to equilibrium for a class of de Broglie-Bohm-type theories
Samuel Colin, Ward Struyve
The de Broglie-Bohm theory is about non-relativistic point-particles that move deterministically along trajectories. The theory reproduces the predictions of standard quantum theor…
On Epstein's trajectory model of non-relativistic quantum mechanics
Ward Struyve
In 1952 Bohm presented a theory about non-relativistic point-particles moving along deterministic trajectories and showed how it reproduces the predictions of standard quantum theo…
De Broglie-Bohm Guidance Equations for Arbitrary Hamiltonians
Ward Struyve, Antony Valentini
In a pilot-wave theory, an individual closed system is described by a wavefunction and configuration . The evolution of the wavefunction and configuration are respectivel…
Pilot-wave theory and quantum fields
Ward Struyve
Pilot-wave theories provide possible solutions to the measurement problem. In such theories, quantum systems are not only described by the state vector, but also by some additional…
A minimalist pilot-wave model for quantum electrodynamics
W. Struyve, H. Westman
We present a way to construct a pilot-wave model for quantum electrodynamics. The idea is to introduce beables corresponding only to the bosonic degrees of freedom and not to the f…
On the Uniqueness of Quantum Equilibrium in Bohmian Mechanics
S. Goldstein, W. Struyve
In Bohmian mechanics the distribution is regarded as the equilibrium distribution. We consider its uniqueness, finding that it is the unique equivariant distribution that i…
