The ontology of Bohmian mechanics
Bohmian mechanics dispositionalism Humeanism law of motion non-locality primitive ontology wave-function
2016/5/30
The paper points out that the modern formulation of Bohm’s quantum theory known as Bohmian mechanics is committed only to particles’ positions and a law of motion. We explain how this view can avoid t...
Statistical VS Wave Realism in the Foundations of Quantum Mechanics
quantum realism quantum states wavefunction
2016/5/30
Different realistic attitudes towards wavefunctions and quantum states are as old as quantum theory itself. Recently Pusey, Barret and Rudolph (PBR) on the one hand, and Auletta and Tarozzi (AT) on th...
Non-equilibrium in Stochastic Mechanics
stochastic mechanics non-equilibrium non-linear Schroedinger equations non-locality pilot-wave theory
2016/5/27
The notion of non-equilibrium, in the sense of a particle distribution other than
rho equal psi squared, is imported into Nelson’s stochastic mechanics, and described in terms of effective wavefunct...
On the Metaphysics of Quantum Mechanics
quantum mechanics Bohmian mechanics Everettian quantum mechanics GWR theory primitive ontology wave function ontology
2016/5/27
What is quantum mechanics about? The most natural way to interpret quantum mechanics realistically as a theory about the world might seem to be what is called wave function ontology: the view accordin...
The Montevideo interpretation of quantum mechanics: frequently asked questions
Measurement problem interpretation of quantum mechanics
2009/11/20
In a series of recent papers we have introduced a new interpretation of quantum mechanics, whichfor brevity we will call the Montevideo interpretation. In it, the quantum to classical transition isach...
Classical Mechanics Is Lagrangian; It Is Not Hamiltonian; The Semantics of Physical Theory Is Not Semantical
classical mechanics Lagrangian mechanics Hamiltonian mechanics
2009/11/18
One can (for the most part) formulate a model of a classical system
in either the Lagrangian or the Hamiltonian framework. Though it is
often thought that those two formulations are equivalent in al...
Can (quantum) information be sorted out from quantum mechanics?
Quantum Information Laws of physics Observers and objects
2009/11/18
We shall draw an affirmative answer to the question posed in the title. The key point will be a quantum description of physical reality. Once fixed at ontic level two basic elements, namely the laws o...
Entanglement, Upper Probabilities and Decoherence in Quantum Mechanics
Decoherence upper probabilities Bell states
2009/9/16
Computation of decay time for entangled quantum systems is an important aspect of decoherence theories. Here we explore this topic from the standpoint of computing the decay time to the existence of a...
Coexistence of several interpretations of quantum mechanics and the fruitfulness of scientific works
Fruitfulness of works re-using works quantum mechanics coexistence of interpretations
2009/6/24
The coexistence of several interpretations of one theory is considered through the example of non-relativistic quantum mechanics. The problem considered is whether physicists manage to work properly i...
Quantum Mechanics on Spacetime I: Spacetime State Realism
spacetime state realism wave-function realism quantum ontology non-separability narratability
2009/6/19
What ontology does realism about the quantum state suggest? The main extant view in contemporary philosophy of physics is wave-function realism. We elaborate the sense in which wave-function realism d...
Structural Correspondence, Indirect Reference, and Partial Truth: Phlogiston Theory and Newtonian Mechanics
correspondence principle reference theoretical terms scientific realism
2009/6/18
This paper elaborates on the following correspondence theorem (which has been defended and formally proved elsewhere): if theory T has been empirically successful in a domain of applications A, but wa...
The Consistent Histories Interpretation of Quantum Mechanics
quantum mechanics physics interpretation consistent histories
2009/6/11
The consistent histories reformulation of quantum mechanics was developed by Robert Griffiths, given a formal logical systematization by Roland Omn\`{e}s, and under the label `decoherent histories', w...
This paper analyses the phenomenon of entanglement exchange in Bohm's pilot wave interpretation of quantum mechanics. The interesting feature of the phenomenon is that systems become entangled without...
Typicality and the Approach to Equilibrium in Boltzmannian Statistical Mechanics
Typicality probability Boltzmann approach to equilibrium non-equilibrium
2009/3/27
Systems prepared in a non-equilibrium state approach, and eventually reach, equilibrium. Why do they do so? An important contemporary version of the Boltzmannian approach to statistical mechanics answ...
Counterfactuals and non-locality of quantum mechanics
qyantum mechanics non-locality realism
2008/4/22
In the paper the proof of the non-locality of quantum mechanics, given recently by H. Stapp and D. Bedford, and appealing to the GHZ example, is analyzed. The proof does not contain any explicit assum...
