It was found recently that tunneling probabilities over a barrier is roughly twice as large as that given by standard WKB formula. Here we explained how this come from and showed that WKB method does ...
Path Integrals and the WKB approximation in Loop Quantum Cosmology
Path Integrals WKB approximation Loop Quantum Cosmology
2010/12/20
We follow the Feynman procedure to obtain a path integral formulation of loop quantum cosmology starting from the Hilbert space framework. Quantum geometry effects modify the weight associated with ea...
Unruh radiation is the thermal flux seen by an accelerated observer moving through Minkowski spacetime. In this article we study Unruh radiation as tunneling through a barrier. We use a WKB-like metho...
Quantization of Reparametrized Systems Using the WKB Method
Singular Lagrangian Parametrized systems WKB Approximation
2010/4/12
The quantization of reparametrized systems is discussed using the WKB approximation. The Hamilton-Jacobi function, the equations of motion and the wave function---which the conditions constrain in the...
