Can Quantum Field Theory be Recovered from Time-Symmetric Stochastic Mechanics? Part II: Prospects for a Trajectory Interpretation
Simon Friederich, Mritunjay Tyagi
In a companion paper we derived a unique time-reversal-invariant stochastic generalization of the Liouville equation and showed that it coincides with the evolution equation for th…
Can Quantum Field Theory be Recovered from Time-Symmetric Stochastic Mechanics? Part I: Generalizing the Liouville Equation
Simon Friederich, Mritunjay Tyagi
We explore whether quantum field theory can be understood as the statistical mechanics of a time-reversal-invariant stochastic generalization of Hamiltonian dynamics. The motivatio…
Kochen-Specker non-contextuality through the lens of quantization
Simon Friederich, Mritunjay Tyagi
The Kochen-Specker theorem shows that it is impossible to assign sharp values to all dynamical variables in quantum mechanics in such a way that the algebraic relations among the v…
Time evolution of the Husimi and Glauber-Sudarshan functions in terms of complementary Hamiltonian symbols
Mritunjay Tyagi, Simon Friederich
We present a compact, systematic formulation of the dynamics of the Husimi Q- and Glauber-Sudarshan P-phase space distribution functions expressed in terms of their \emph{complemen…
Origin of time and probability in quantum cosmology
Leonardo Chataignier, Claus Kiefer, Mritunjay Tyagi
We discuss how the classical notions of time and causal structure may emerge together with quantum-mechanical probabilities from a universal quantum state. For this, the process of…
