The Bohmian trajectories for an electron going through the two-slit experiment. A similar pattern was also extrapolated from weak measurements of single photons. [3] The double-slit experiment is an illustration of wave–particle duality. In it, a beam of particles (such as electrons) travels through a barrier that has two slits.
In theoretical physics, the pilot wave theory, also known as Bohmian mechanics, was the first known example of a hidden-variable theory, presented by Louis de Broglie in 1927. Its more modern version, the de Broglie–Bohm theory , interprets quantum mechanics as a deterministic theory, and avoids issues such as wave function collapse , and the ...
The Bohmian trajectories for an electron going through the two-slit experiment. A similar pattern was also observed for single photons. [16] During his early period, Bohm made a number of significant contributions to physics, particularly quantum mechanics and relativity theory.
The quantum potential or quantum potentiality is a central concept of the de Broglie–Bohm formulation of quantum mechanics, introduced by David Bohm in 1952.. Initially presented under the name quantum-mechanical potential, subsequently quantum potential, it was later elaborated upon by Bohm and Basil Hiley in its interpretation as an information potential which acts on a quantum particle.
In 2005 Wyatt published his book Quantum dynamics with trajectories with contributions by Corey J. Trahan. Wyatt holds a W. T. Doherty professorship in chemistry at the Austin University of Texas. [2] An October 2007 edition of the Journal of Physical Chemistry A is a Festschrift dedicated to the work of Robert E. Wyatt and his group. Wyatt has ...
His publications on trajectory-based methods include: Eric R. Bittner, Donald J. Kouri, Sean Derrickson, and Jeremy B. Maddox: Variational Quantum Hydrodynamics , in: Xavier Oriols and Jordi Mompart (eds.), Applied Bohmian Dynamics (invited review chapter), 2010, [1]
So while a single particle will travel through one particular slit in the double-slit experiment, the so-called "pilot wave" that influences it will travel through both. The two slit de Broglie-Bohm trajectories were first calculated by Chris Dewdney while working with Chris Philippidis and Basil Hiley at Birkbeck College (London). [100]
Thus Bohmian mechanics restores the conventional view of the world and its past. The past is out there as an objective history unalterable retroactively by delayed choice. The quantum potential contains information about the boundary conditions defining the system, and hence any change of the experimental set up is reflected in changes in the ...
