Tunneling Times

ABSTRACT: The tunneling time problem was a very popular problem at the end of the 20th century.In Quantum Mechanics only observables can be measured, i.e. these observables are real quantities. From mathematics it is well known that only hermitian operators have real eigenvalues, therefore we associate observables as eigenvalues of Hermitian operators. Until now no Hermitian operator for the time was not found. Therefore many approaches in order to determine the time a particle spends in a region or needs to travel across a region are developed. Based on this the Bohmian Dwell Time, the Buttiker Landauer Time, the Larmor Clock, and the minimal tunneling time are presented and discussed in this thesis. Keywords: Quantum Mechanics, Traversal Time, Tunneling Time, Larmor Clock, Dwell Time. ……………………………………………………………………………………………………………………………………………………………………………………………………………………
