Time separation as a hidden variable to the Copenhagen school of quantum mechanics
hidden variable Copenhagen school
2010/12/27
The Bohr radius is a space-like separation between the proton and electron in the hydrogen atom. According to the Copenhagen school of quantum mechanics, the proton is sitting in the absolute Lorentz ...
Fast Converging Path Integrals for Time-Dependent Potentials II: Generalization to Many-body Systems and Real-Time Formalism
Fast Converging Path Integrals Time-Dependent Potentials II
2010/12/27
Based on a previously developed recursive approach for calculating the short-time expansion of the propagator for systems with time-independent potentials and its time-dependent generalization for sim...
Dynamical Implications of Adjustments to Proper Time Caused by Higher Dimensions: A Note
Dynamical Implications Higher Dimensions
2010/11/16
When the proper time of general relativity is adjusted to reflect the possible existence of higher dimensions, small dynamical effects appear in spacetime of the sort usually associated with the cosmo...
Employing combination procedures to short-time EOP prediction
combination procedures short-time EOP prediction
2010/11/16
A well known problem with Earth Orientation Parameters (EOP) prediction is that a prediction strategy proved to be the best for some testing time span and prediction length may not remain the same for...
Relativistic Constraints for a Naturalistic Metaphysics of Time
Relativistic Constraints Naturalistic Metaphysics of Time
2010/11/16
The traditional metaphysical debate between static and dynamic views in the philosophy of time is examined in light of considerations concerning the nature of time in physical theory. Adapting the fo...
Time evolution of Wigner functions governed by bipartite Hamiltonian system with kinetic coupling
entangled Wigner operator Wigner function evolution entangled state representation
2010/6/30
For the bipartite Hamiltonian system with kinetic coupling, we derive time evolution equation of Wigner functions by virtue of the bipartite entangled state representation and entangled Wigner operato...
Chaotic instantons and enhancement of tunneling in kicked double-well system with time-reversal symmetry
time-reversal symmetry Chaotic instantons dynamical tunneling
2010/4/2
Chaotic instanton approach is used to describe dynamical tunneling in kicked double well system. Effective Hamiltonian for the kicked system is obtained using matrix expansion formula for operator exp...
A model-insensitive determination of First-hitting-time densities with Application to Equity default-swaps
First-hitting-time densities Equity default-swaps
2010/4/27
Equity default-swaps pay the holder a fixed amount of money when the underlying spot level touches a (far-down) barrier during the life of the instrument. While most pricing models give reasonable res...
Time Dependent Entropy of Constant Force Motion
Path integral joint entropy constant force motion
2010/4/9
Time dependent entropy of constant force motion is investigated. Obtained is the joint entropy, also known as the Leipnik entropy. The main purpose of this work is to calculate the Leipnik entropy via...
Continuous Time Stochastic Models for Vehicular Traffic on Highways
Continuous Time Stochastic Models Vehicular Traffic Highways
2010/10/19
We have simulated a continuous time version of the Nagel-Schreckenberger model of vehicular traffic on highways and calculated the flux as a function of vehicle density. In the low density regime the ...
