How to use Unimodular Quantum Cosmology for the Prediction of a late-time Classical Universe?
Natascha Riahi
Unimodular quantum cosmology admits wavepacket solutions that evolve according to a kind of Schrödinger equation. Though this theory is equivalent to general relativity on the clas…
Wavepacket evolution in unimodular quantum cosmology
Natascha Riahi
The unimodular theory of gravity admits a canonical quantization of minisuperspace models without the problem of time. We derive instead a kind of Schrödinger equation. We have fou…
Analysis of wavepacket tunneling with the method of Laplace transformation
Natascha Riahi
We use the method of Laplace transformation to determine the dynamics of a wave packet that passes a barrier by tunneling. We investigate the transmitted wave packet and find that…
Solving the time-dependent Schrödinger equation via Laplace transform
Natascha Riahi
We show how the Laplace transform can be used to give a solution of the time-dependent Schrödinger equation for an arbitrary initial wave packet if the solution of the stationary e…
The evolution of quantal uncertainties in at most quadratic potentials
Natascha Riahi
We investigate the time evolution of momentum and position uncertainties for wave packets of arbitrary shape in at most quadratic potentials. We consider all possible cases of pote…
